Vernier Calliper (Product Code: SCL202/01) is a stainless-steel sliding measuring instrument used to measure the length and diameter of small objects more precisely than a ruler in school and college physics practicals. This IME-type calliper is 15 cm long, has a listed least count of 0.01 mm and a thumb movement that slides the jaws smoothly. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for schools sourcing a Vernier caliper in India for class sets.

Specifications

What Is the Vernier Calliper Used For?

A vernier calliper lets students read a measurement that falls between two graduation marks on the main scale. The sliding vernier scale performs a mechanical interpolation, which increases resolution and reduces the guesswork of estimating by eye – the student simply looks for the vernier line that lines up most closely with a main-scale line. It is a routine item of physics practical equipment for CBSE and state-board laboratories, used to find the diameter of a small sphere or cylinder and the dimensions of a regular block, and from these its volume.

Before measuring, close the jaws and check whether the vernier zero sits exactly on the main-scale zero; note any zero error with its sign. Grip the object gently between the jaws using the thumb movement, read the main scale just before the vernier zero, add the coinciding vernier division multiplied by the least count, and correct for zero error. Repeat at different positions and average the readings.

What to Specify When Ordering

• The number of callipers – usually one per student pair or practical group.
• Confirm that a 15 cm length and the listed 0.01 mm least count match your practical syllabus.
• Whether screw gauges, spheres or blocks for the same experiments should be quoted with them.

Bob/Metallic Sphere (Small) With Hooks (Product Code: SCL205/02) is a small brass pendulum bob with a hook, used as the swinging mass in simple pendulum experiments in school and college physics labs. The 18 mm polished brass sphere hangs from a thread by its hook, so students can study time period, effective length and simple harmonic motion with a simple pendulum apparatus in India’s school labs. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Pendulum Bob Used For?

In the classic practical, a thread is tied to the bob’s hook and clamped between the halves of a split cork held in a stand. Students measure the bob’s diameter with a vernier calliper, add the radius to the thread length to get the effective length, displace the bob through a small angle and time 20 oscillations with a stop clock. Repeating this for several lengths and plotting length against the square of the time period gives a straight line from which g can be found using g = 4π²L/T².

Used with a full pendulum set-up, the bob makes the physics of pendulum motion visible and hands-on, which is why it belongs in any SHM experiment kit in India. Keep the amplitude small, start counting as the bob passes its mean position, and shield the set-up from fans or draughts. The polished, anti-corrosive brass can simply be wiped clean and stored dry.

What to Specify When Ordering

• The number of bobs – one per pendulum set-up, plus spares for a practical examination.
• Whether stands, clamps, split corks or stop clocks should be quoted with the bobs.
• The delivery location for your laboratory or dealer stock.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of this brass pendulum bob. It is made at the company’s own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader, and is sent factory-direct to schools, colleges, laboratories, dealers and importers. Repeat orders and replacement bobs are handled by the manufacturer itself – just ask us. Read more on our company profile.

Wooden Block Small Size (Product Code: SCL207/03) is a rectangular wooden block fitted with a hook, used to study sliding friction and pulling force in school physics practicals. It measures 100 x 75 x 15 mm and has smooth faces with no splinters or cracks, so young students can handle it safely and drag it across different surfaces. This piece of mechanics lab equipment is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Wooden Block Used For?

In a typical friction experiment, a spring balance is attached to the hook and the block is pulled slowly across a table, a glass sheet or sandpaper. Students note the reading just as the block starts to move (limiting friction) and again while it slides steadily, then repeat on other surfaces to compare them.

Because the block has three different faces — 100 x 75 mm, 100 x 15 mm and 75 x 15 mm — the same test can be run on the broad face and on the narrow edges to show that friction depends on the surfaces and the load, not on the contact area. Placing known masses on top raises the normal force, and resting the block on an inclined plane lets a class find the angle at which it just begins to slide.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of the Wooden Block Small Size. The blocks are made at the company's own licensed factory at Saha, Ambala, Haryana, India, not bought in from a trader, and are supplied factory-direct to schools, colleges, lab dealers and importers.

Because the maker handles the order itself, top-up quantities for new class sections or replacement blocks can be requested straight from the factory team — just ask us. More about the company is on the ScienceLab company profile.

Beaker (Glass) (Product Code: SCL209/04) is a 250 ml graduated borosilicate glass beaker used to hold, heat and roughly measure water and other liquids in physics and general science practicals. Its clear, heat-resistant and chemical-resistant glass lets students watch what happens inside while the contents are warmed or mixed. This lab glassware is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Glass Beaker Used For?

In the physics lab a 250 ml beaker is the everyday vessel for hot-water work: warming water for cooling-curve and heat experiments, holding water into which a solid is lowered from a spring balance to show Archimedes' principle, and collecting liquids for density readings. Because borosilicate glass tolerates heat, the beaker can be placed on a wire gauze over a burner.

The graduations give a quick approximate volume; for exact volumes, pour into a measuring cylinder. Heat the beaker gradually, never put it hot onto a cold or wet surface, and lift it with tongs. Stocking enough beakers for every bench is a basic part of physics lab equipment for schools, since the same vessel serves heat, fluid and mixing activities.

What to Specify When Ordering

• Capacity — this listing is the 250 ml graduated beaker; name any other volumes you need separately.
• Quantity — how many beakers per bench or student group.
• Handling items — whether tongs or a stand should be quoted with the beakers.

Screw Gauge (Product Code: SCL211/05) is a micrometer screw gauge used to measure small outside dimensions, such as the diameter of a wire or the thickness of a sheet, in physics practicals. It covers 0–25 mm with a precision of 0.01 mm, using an accurately machined stainless steel rod in a nickel-plated brass frame with a ratchet top and lock. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Screw Gauge Used For?

School and college students use the screw gauge to find the diameter of a resistance wire before calculating its resistivity, the thickness of a metal or glass sheet, and the diameter of a small ball. The object is placed between the fixed stud and the moving rod, and the reading is taken from the main scale plus the circular scale on the thimble.

Good practice: close the gauge with the ratchet until it slips rather than turning the thimble directly, check and record any zero error before starting, lock the rod before lifting the gauge to read it, and take readings at several points along a wire. As a screw gauge for school physics labs, it pairs naturally with a vernier calliper for larger objects.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this Screw Gauge. It is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and packed in its plastic case there before dispatch to schools, colleges, dealers and importers.

Buying from the maker means one point of contact for bulk quantities, repeat orders and questions about replacement cases or parts — just ask us. See the company profile for more about ScienceLab.

• Steel Ball — a small sphere whose diameter can be measured.

Browse the Physics Lab category for other measuring instruments.

Frequently Asked Questions

What is the range and precision of the Screw Gauge?
The Screw Gauge measures outside dimensions from 0 to 25 mm with a precision of 0.01 mm (1/100 mm). That makes it suitable for wire diameters, sheet thicknesses and small spheres in school and college practicals.

What is the Screw Gauge made of?
The Screw Gauge has a nickel-plated brass frame with a ratchet top and an accurately machined stainless steel measuring rod. It is a lock type gauge, so the reading can be held while the gauge is removed from the object.

How do I check the zero error of the Screw Gauge?
To check the Screw Gauge for zero error, close it gently using the ratchet with nothing between the faces. If the circular-scale zero does not line up with the reference line, note how many divisions it is above or below and correct every reading.

Does the Screw Gauge come with a case?
Yes. The Screw Gauge is supplied in a plastic case, which protects the measuring faces and ratchet between lessons. Wipe the gauge clean and return it to the case after each use to keep dust off the thread.

Metal/Steel Sheet (Rectangular) (Product Code: SCL213/06) is a plain rectangular steel sheet used for measurement and surface experiments in school physics practicals. At 12 cm x 8 cm it is a handy piece for students to measure with a scale, vernier calliper and screw gauge, work out area, volume and density, and compare sliding friction on a metal surface. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Steel Sheet Used For?

A common physics practical is to find the density of a regular solid. Students measure the length and breadth of the sheet with a metre rule or vernier calliper, read its thickness at several points with a screw gauge, multiply to get the volume, then weigh the sheet and divide mass by volume. The plain, flat surface makes repeat readings consistent.

The same sheet also serves as a smooth metal surface in friction activities — a wooden block pulled across it gives a different spring-balance reading from wood on wood or on sandpaper. As one of the simpler physics practical equipment items, it is worth keeping one per bench so each group can measure independently. Handle the edges with care and wipe the sheet dry after use.

OEM Manufacturer

This steel sheet is manufactured by Jain Scientific Equipments Private Limited — the company behind the ScienceLab brand — as the OEM (original equipment manufacturer). Production is at its own licensed factory at Saha, Ambala, Haryana, India, and the sheets go out factory-direct to schools, colleges, dealers and importers.

It has a board of about 65 x 50 cm, two 50 mm aluminium pulleys that clamp anywhere on the board, three mass hangers and twelve 50 g brass slotted masses, with a stand. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Parallelogram Law Apparatus Used For?

Often called Gravesand's apparatus, the board is set upright on its stand with a sheet of paper pinned to it. A thread passes over both pulleys with a hanger at each end, and a third hanger is tied to the thread between them. When the three loads come to rest, students mark the thread directions, draw two forces to scale as adjacent sides of a parallelogram and check that the diagonal matches the third load in size and direction.

Moving the clamped pulleys changes the angles, so each group can repeat the test with new settings; the same set-up can also find an unknown weight. Tap the board gently before marking to reduce pulley friction, and keep the knot and hangers clear of the board. It is standard mechanics lab equipment for the vector-addition practical in senior school physics.

What to Specify When Ordering

• Number of complete sets, each with board, two pulleys, three hangers, twelve 50 g masses and stand.

Inclined Plane with Roller & Pan (Product Code: SCL220/010) is a hinged inclined plane used to study forces along a slope and find coefficients of friction between materials in physics labs. Its aluminium plane measures 600 x 100 mm, an arch scale sets the incline from 0° to 45° in 1° steps, and a cylindrical metal roller, scale pan with cord, trolley and pulley are included. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Inclined Plane Used For?

For the force experiment, the plane is raised to a chosen angle on the arch scale and the roller is placed on it. A cord from the roller runs over the pulley to the scale pan, and masses are added until the roller stays still; the load in the pan then balances the component of the roller's weight acting down the slope, which students compare with the value from W sinθ.

For friction, a block of wood, metal or another material is placed on the plane and the angle is increased slowly until the block just starts to slide; the tangent of that angle gives the coefficient of static friction. This makes it a practical inclined plane apparatus for friction experiments in senior secondary physics. Keep the plane surface clean and dry between tests so results stay comparable.

What to Specify When Ordering

• Base type — confirm whether you need the aluminium base board or the wooden base described in the listing.
• Number of sets for your lab benches.
• Masses for the scale pan and blocks of different materials, if they should be quoted with the plane.

The set is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Weight Box Used For?

On a physical balance the object goes on the left pan and masses from the box are added to the right pan, starting with the largest likely piece and working down until the beam rests level; the total of the masses on the pan is the mass of the object. Classes use this for finding the mass of solids before density calculations and for comparing results with a digital balance.

The same masses act as known loads in mechanics practicals — in the scale pan of an inclined plane, on a thread over a bench pulley, or on a force board. Lift the pieces with forceps rather than fingers, since sweat and dirt slowly change a mass, and return every piece to its place in the box. It is basic physics lab equipment for schools that still teach weighing on a beam balance.

What to Specify When Ordering

• Mass range — this box covers 1 g to 200 g; ask us for the exact list of pieces in the set.
• Number of boxes, usually one per balance.
• Whether forceps or a matching physical balance should be included in the quotation.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its brand ScienceLab, is the OEM (original equipment manufacturer) of the Weight Box (Physical). The chrome-plated brass masses are made and boxed at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct rather than through traders.

If a piece goes missing from a school set, a replacement mass or a complete new box can be requested from the manufacturer that made it — just ask us. More on the company is on the ScienceLab profile.

Physical Balance (Digital) (Product Code: SCL226/013) is a top-loading electronic balance used to find the mass of solids and liquids in school physics and science practicals. It weighs up to 600 g with a least count of 0.01 g, works on battery or adaptor, and has auto zero tracking, a large 6-digit LCD and low-battery indication. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as one of its digital measuring instruments for teaching labs.

Specifications

What Is the Digital Physical Balance Used For?

Students use the balance to weigh a metal sheet, a wooden block or a bob before density, friction or pendulum calculations, and to weigh a beaker before and after filling to find the mass of a liquid. The two-decimal readout speeds up practicals that would otherwise need a two-pan balance and a box of masses, and the large display lets a group read the value together.

Set the balance on a firm, level bench away from draughts and vibration, let the reading settle at zero before loading, and never place more than 600 g on the pan. Run it on the adaptor for long sessions and switch to batteries when the balance moves between rooms; the low-battery indication warns when cells need changing. It suits physics lab instruments used for routine weighing rather than analytical work.

What to Specify When Ordering

• Capacity and least count needed — this model is listed at 600 g and 0.01 g.
• Accuracy — the listing gives 1 g with adapter; confirm the figure you need with the quotation.
• Number of balances per lab and whether batteries should be included.

Spring Balance, Tubular (Product Code: SCL228/014) is a plastic-bodied tubular spring balance used to measure weight and pulling force in school physics and general science lessons. It reads loads up to 1 kg, hangs from a suspension ring and carries the object on a load hook, which makes it quick to use for weighing in air and in water or for pulling a block across a bench. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Tubular Spring Balance Used For?

In Archimedes' principle practicals, a solid is hung from the hook and weighed in air, then lowered into a beaker of water; the drop in reading is the upthrust. In friction work the balance is hooked to a block and pulled level along the bench, and the reading as the block starts to move gives the limiting friction.

Because the spring stretches in proportion to the load, the balance also helps introduce Hooke's law before students build their own spring set-up. Hold it vertical when weighing, check that the pointer rests at zero before each reading, stay within the 1 kg capacity and never let a loaded spring snap back. It is simple mechanics lab equipment that every bench group can keep at hand.

OEM Manufacturer

The Spring Balance, Tubular is manufactured by Jain Scientific Equipments Private Limited under its ScienceLab brand, and the company is the OEM (original equipment manufacturer). The balances are made at its own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers.

Class sets and repeat orders are quoted by the manufacturer itself, so larger quantities for new sections can be planned in one enquiry — just ask us. See the ScienceLab profile for company details.

Related Physics Lab Equipment

Apparatus used with the spring balance in force and fluid practicals:

• Wooden Block Small Size — hook it to the balance to measure friction.
• Beaker (Glass) — holds the water for weighing a solid when immersed.
• Vertical Stand With 3 Clamps — supports the balance while readings are taken.
• Hangers with Slotted Weights — known loads to test the balance readings.
• Balance Spring Tubular Plastic — another tubular spring balance listing to compare.

Find more apparatus in the Physics Lab category.

Frequently Asked Questions

What is the capacity of the Spring Balance, Tubular?

Meter Scale 100 cm (Product Code: SCL232/016) is a graduated steel rule, one metre long, used to measure lengths and distances in school and laboratory physics practicals. Its full 100 cm length covers pendulum lengths, object and image distances on a bench and other long measurements that a short rule cannot take in one reading. This physics lab equipment is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Metre Scale Used For?

A metre rule is the first measuring tool in most mechanics and optics practicals. Students use it to set the length of a simple pendulum from the point of suspension to the centre of the bob, to measure object and image distances when finding the focal length of a lens or mirror, and to record the extension of a spring as loads are added.

To avoid parallax, read the scale with your eye directly above the mark, and if the zero end is worn, start from a clear graduation and subtract it. Lay the steel rule flat or on edge against the object rather than at an angle. For short, fine measurements switch to a vernier calliper; for anything longer than a metre, use a measuring tape.

What to Specify When Ordering

• Length — this listing is the full 100 cm scale; a shorter half-metre scale is listed separately.
• Number of scales per bench or student group.
• Any other measuring instruments to be quoted in the same order.

OEM Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of the Meter Scale 100 cm. The scales are made at the company's own licensed factory at Saha, Ambala, Haryana, India, and go factory-direct to schools, colleges, dealers and importers instead of passing through traders.

Ordering from the maker keeps quotations simple when scales are bought with other lab apparatus, and repeat orders are handled by the same team — just ask us. The ScienceLab profile has more about the company.

Related Physics Lab Equipment

Other measuring tools and apparatus used with the metre scale:

• Meter Scale 50 cm — a shorter rule for bench and drawing work.
• Semi Circular Meter Scale — another scale in the physics range.
• Vernier Calliper — for small lengths that need finer readings.
• Bob/Metallic Sphere (Small) With Hooks — the pendulum bob whose length is measured.
• Optical Bench with 3 Stands — lens and mirror set-ups whose distances the scale measures.

See the complete Physics Lab category for more instruments.

Frequently Asked Questions

How long is the Meter Scale 100 cm and what is it made of?
The Meter Scale 100 cm is a graduated steel rule one metre long. It is intended for use in laboratories and schools, where it measures pendulum lengths, lens and mirror distances and spring extensions.

Why choose a steel Meter Scale 100 cm instead of a wooden one?
A steel Meter Scale 100 cm keeps a straight, hard edge and does not swell or warp with damp the way wood can. That makes it a durable choice for busy school labs where scales are handled by many students.

How do I avoid reading errors with the Meter Scale 100 cm?
When using the Meter Scale 100 cm, keep your eye directly above the mark to avoid parallax, and if the zero end is worn, measure from a clear graduation and subtract it. Take repeat readings and average them.

Who manufactures the Meter Scale 100 cm?
The Meter Scale 100 cm is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Quotations are provided directly by the manufacturer, not through a trader.

Meter Scale 50 cm (Product Code: SCL234/017) is a graduated steel half-metre rule used for measuring lengths on the lab bench in schools and laboratories. At 50 cm it is easier to handle than a full metre rule when drawing ray diagrams, reading spring extensions or checking the size of small apparatus, and it fits neatly into a student kit. It is one of the school lab instruments made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Half-Metre Scale Used For?

The shorter length makes this scale the everyday rule for work done flat on the bench. In optics practicals students use its steel edge to draw incident and refracted rays through a glass slab or prism on a drawing board; in the parallelogram-law practical they draw force lines to scale; and with a spring clamped to a stand they read the extension as loads are added.

Hold the scale on edge against the line being measured and read with your eye straight above the mark to avoid parallax. Because it is steel, the edge stays straight for ruling lines, and the rule can be wiped clean after use with ink or water. Keep one per student pair and a metre rule per bench for longer distances.

OEM Manufacturer

The Meter Scale 50 cm is an OEM product: Jain Scientific Equipments Private Limited, the company that trades as ScienceLab, is its original equipment manufacturer. The scales are made at its own licensed factory at Saha, Ambala, Haryana, India, and dispatched directly to schools, colleges, dealers and importers.

Because the manufacturer quotes directly, student-kit quantities can be combined with other bench apparatus in one order — just ask us. Background on the company is on the ScienceLab profile.

Related Physics Lab Equipment

Items that pair with the half-metre scale on the bench:

• Meter Scale 100 cm — the full-metre rule for longer distances.
• Half Meter Scale — the half-metre scale in the maths lab range.

• Law of Parallelogram Apparatus (Grave Sand Apparatus) — force lines are drawn to scale with the rule.
• Vernier Calliper — for small lengths that need finer readings.

Browse the Physics Lab category for more bench apparatus.

Frequently Asked Questions

How long is the Meter Scale 50 cm and what is it made of?
The Meter Scale 50 cm is a graduated steel rule half a metre long. It is intended for laboratories and schools, where it is used for bench measurements, ray diagrams and reading spring extensions.

When should I choose the Meter Scale 50 cm over a full metre rule?
Choose the Meter Scale 50 cm for work on the bench top, drawing boards and student kits, where a shorter rule is easier to handle. Use a full metre rule for pendulum lengths and optical-bench distances.

Can the Meter Scale 50 cm be used as a straight edge?
Yes. The steel Meter Scale 50 cm keeps a straight edge, so students can rule ray diagrams and force lines with it as well as measure. Wipe the edge clean after drawing so ink or graphite does not hide the graduations.

Bench Pulley (Product Code: SCL238/019) is a clamp-on pulley that fixes to the edge of a lab bench or table so a string can pass over it to a hanging load in mechanics experiments. It has a 75 mm diameter pulley wheel and comes with a complete clamping arrangement, so it can be set up wherever the bench edge allows. It is part of the pulley system lab range made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Bench Pulley Used For?

Clamped at the end of a bench, the pulley turns a horizontal pull into a vertical hanging load. In friction practicals a thread runs from a block on the bench over the pulley to a hanger, and slotted masses are added until the block just starts to move. In motion practicals the same arrangement pulls a trolley so students can relate the hanging load to the acceleration.

Set the pulley so the thread leaves the block parallel to the bench top, check that the wheel turns freely before loading, and keep the hanging load clear of the floor and the bench legs. Two pulleys clamped at opposite ends of a bench can also be used to balance loads in force demonstrations.

OEM Manufacturer

Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, is the OEM (original equipment manufacturer) of the Bench Pulley. The pulley wheel and clamp are made and assembled at its own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers.

Semi Circular Meter Scale (Product Code: SCL241/020) is a steel semicircular scale used to measure and mark angles, and to gauge small depths, in school and college physics laboratories. Students and teachers use it for angle work in optics and mechanics practicals; its etched 0° to 180° graduations run in opposite directions, so an angle can be read from either side. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its physics lab equipment range.

Specifications

What Is the Semi Circular Scale Used For?

In the physics lab the Semi Circular Meter Scale is used wherever an angle has to be measured or drawn: marking the angles of incidence and refraction when tracing rays through a glass slab or prism, reading the angle between the strings of a parallelogram-of-forces set-up, or checking the slope of an inclined plane. Because the graduations are numbered both ways, a student can read an angle measured from the left or the right without turning the scale around.

The depth gauge scale adds a second job: checking how deep a slot, recess or groove is. Etched markings stay readable after repeated classroom handling, which suits shared school physics lab equipment. For clean readings, place the straight edge exactly along one arm of the angle, read at eye level, and wipe the steel dry after practical sessions.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) of the Semi Circular Meter Scale. The scale is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, so schools, colleges, laboratory dealers and importers deal with the maker itself rather than a trading intermediary. If you need matching scales for several benches or a repeat order later, ask us and the manufacturer will quote it directly. More about the company is on the ScienceLab company profile page.

Wall Mount For Searle Apparatus (Product Code: SCL246/022) is a wall-fixing support used to hang Searle's apparatus for the Young's modulus experiment in school and college physics laboratories. Teachers and lab assistants install it where the lab needs a permanent, steady suspension point so the two test wires hang freely. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for labs running the Searle method Young modulus practical.

Key Details

What Is the Searle Apparatus Wall Mount Used For?

In Searle's method two wires of the same material hang side by side from one support. The reference wire carries a steady load to keep it straight, while the experimental wire is loaded in steps and its extension is read against the reference with the spirit level and micrometer. The wall mount gives both wires that common hanging point on a solid wall, keeping the set-up out of the way of benches and leaving a clear drop for the frames and loads.

For a reliable practical, fix the mount on a sound masonry wall at a height that leaves room for the full wire length, the frames and the weight hangers below. Check with a plumb line that the wires hang truly vertical before taking readings, add and remove loads gently, and keep students clear of the space beneath the hanging weights.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM that makes this wall mount as well as the Searle's apparatus it is meant to carry. Production takes place at the company's own licensed factory at Saha, Ambala, Haryana, India, and schools, colleges and dealers order the mount direct from the manufacturer, which helps when a lab wants the mount and apparatus from the same maker. For vendor records, the company is incorporated under CIN U29309HR2020PTC087597 and its factory at 449, HSIIDC Industrial Area, Saha, Ambala operates under Factory Licence AMB-ONLINE-CHD-J-414.

Searle's Apparatus (Product Code: SCL248/023) is a twin-frame extension-measuring apparatus used to determine Young's modulus of the material of a wire in school and college physics laboratories. Senior secondary and undergraduate students use it for elasticity practicals, where a micrometer head reading to 0.01 mm measures how far a loaded wire stretches. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, within its mechanics lab equipment range.

Specifications

What Is Searle's Apparatus Used For?

Searle's Apparatus is the standard set-up for finding Young's modulus by Searle's method, a practical that appears in physics practical equipment lists for CBSE and university labs. One wire carries the counterpoise weight and acts as the reference; the other is loaded in steps. As the loaded wire stretches, its frame slides down relative to the reference frame and tilts the spirit level. Turning the micrometer until the bubble is level again gives the relative displacement, which is the extension.

Young's modulus then follows from stress divided by strain, using the load, the original length of the wire, its cross-sectional area and the measured extension. For consistent results, straighten the wire before clamping it in the self-centring chucks, add loads gently, wait a moment before each reading, and record readings while both loading and unloading so any slip or permanent stretch shows up.

What to Specify When Ordering

• Number of Searle's Apparatus sets needed for your practical batches
• Mounting: the ceiling bracket is included; add the Wall Mount For Searle Apparatus if you prefer a wall fixing
• Whether you need extra brass or steel wires beyond the set of two supplied
• Slotted weights and hangers for loading, which are listed as separate items

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM (original equipment manufacturer) of this Searle's Apparatus and builds it at its own licensed factory at Saha, Ambala, Haryana, India. Because you buy from the manufacturer rather than a reseller, questions about spare wires, the counterpoise weight or other replacement parts go straight to the people who make the apparatus; ask us about availability. Colleges, schools, dealers and importers can all order factory-direct. Company background is on the ScienceLab profile page.

Steel Wire (Product Code: SCL250/024) is a steel test wire used for elasticity and other wire-based experiments in school and college physics laboratories. Lab staff keep it as stock or replacement wire; it is listed with a capacity of 100 gm, and its size suits mechanically swaged fittings. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its physics lab equipment range for India and international markets.

Specifications

What Is Steel Wire Used For?

In physics practicals, steel wire of this kind is typically used as the test wire in Searle's method for Young's modulus, where known loads stretch it by fractions of a millimetre. Keeping stock wire on the shelf lets a lab replace a kinked or over-stretched wire between practical batches instead of reusing one that no longer gives reliable readings. It also serves for simple stretching and load demonstrations.

Handle the wire carefully: store it loosely coiled, avoid sharp bends, and cut lengths with a proper wire cutter so the ends seat cleanly in chucks or fittings. Before a practical, measure the diameter with a screw gauge at several points along the length and use the average, because small diameter errors have a large effect on the calculated modulus.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies this Steel Wire from Ambala, Haryana, India, alongside Searle's apparatus and the other physics items in its catalogue. The company sources the wire for laboratory use and can combine it with apparatus on one quotation, so a lab can reorder test wire and the equipment it is used with from a single supplier. Read about the company on the ScienceLab profile page.

Frequently Asked Questions

What is the Steel Wire made of?
The Steel Wire (code SCL250/024) is made of steel. Steel is stiff compared with metals such as brass, so in Young's modulus practicals it stretches only slightly under load, which makes careful micrometer readings important.

What does the 100 gm capacity of the Steel Wire refer to?
The Steel Wire is listed with a capacity of 100 gm. Please confirm with us what this figure means for your application, along with the diameter and length you need, before ordering through the contact page.

What fittings does the Steel Wire suit?
The Steel Wire is sized to suit mechanically swaged fittings, where a metal sleeve is pressed onto the wire end to form a secure termination. If you will clamp it in apparatus chucks instead, tell us your apparatus so we can check suitability.

Can the Steel Wire be used with Searle's Apparatus?
Steel wire is commonly used in Searle's Apparatus for Young's modulus. To be sure this Steel Wire suits the chucks and length of your apparatus, give us its code or details when you enquire, and we will confirm before quoting.

Who supplies the Steel Wire?

Loose Weight (Product Code: SCL252/025) is a single ½ kg steel mass used to apply a known load in school and college physics experiments. Teachers and students reach for it whenever an extra fixed load is needed on a wire, spring, string or lever, and its silver-coloured steel is chemical resistant. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as everyday physics lab equipment for schools.

Specifications

What Is a Loose Weight Used For?

A loose weight is a stand-alone mass rather than one piece of a slotted set, so it is handy whenever a practical calls for one fixed load. At ½ kg it exerts roughly 4.9 N under normal gravity, a convenient step for loading a spring in a Hooke's law practical, holding a string taut over a bench pulley, adding weight to a wire in an elasticity experiment, or checking the reading of a spring balance.

Because the steel is chemical resistant, the weight can be wiped clean if it is used near liquids on a shared bench. Lower it into place gently rather than dropping it, keep it on a shelf away from glassware, and use a weight box when a practical needs a series of small, precise masses instead of one fixed load.

OEM Manufacturer

Loose weights like this are part of the metal lab ware that Jain Scientific Equipments Private Limited produces under its ScienceLab trading name. As OEM (original equipment manufacturer), the company makes the Loose Weight at its licensed factory at Saha, Ambala, Haryana, India, and dispatches it factory-direct to schools, colleges, laboratory dealers and importers. Repeat orders for matching weights are handled by the manufacturer itself, so just ask us when you need more. The ScienceLab profile page has more about the company.

Frequently Asked Questions

How heavy is the Loose Weight?
The Loose Weight has a capacity of ½ kg (500 g), which corresponds to a force of roughly 4.9 N under normal gravity. It is a single steel mass rather than part of a slotted set, so it adds one fixed load.

What is the Loose Weight made of?
The Loose Weight is made of silver-coloured steel that is chemical resistant. That makes it easy to wipe clean after use on a shared lab bench, including in practicals where liquids are nearby.

Will the Loose Weight fit my hanger or hook?
Whether the Loose Weight suits a particular hanger or hook depends on your set-up. Tell us the apparatus you plan to load through the contact page, and we will confirm suitability or suggest a slotted-weight hanger instead.

Can the Loose Weight be used as a calibration mass?
The Loose Weight is intended as a practical load for physics experiments. Calibration-certificate availability for it should be discussed with us before ordering; for precise mass comparison a weight box is usually the better choice.

Who manufactures the Loose Weight?
The Loose Weight (code SCL252/025) is manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, as the OEM at its own factory in Saha, Ambala, Haryana, India, and is sold factory-direct.

Hangers with Slotted Weights 500 gm (Product Code: SCL258/028) is a hanger-and-slotted-mass set used to load springs, wires and strings in equal steps during physics practicals. Students use it to add 100 gm at a time, because the 500 gm capacity is made up as 5 x 100 gm in black iron, with a hooked design for hanging from balances and apparatus. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Hangers with Slotted Weights Used For?

Step loading is at the heart of many school practicals, and this 500 gm set is one of the everyday physics lab instruments that makes it possible. In a Hooke's law practical the hanger hangs from a spring and 100 gm weights are added one by one while the extension is recorded; the same set loads the experimental wire in Searle's apparatus, pulls a string over a bench pulley, or supplies known forces for moments and equilibrium work.

The slot in each weight lets it slide onto the hanger without unhooking the set-up, so the reading position is not disturbed between loads. Turn successive slots in different directions so the stack stays secure, take readings both while loading and unloading, and wipe the iron weights dry before putting them away as a complete set.

What to Specify When Ordering

• Which set you need: this 500 gm black-iron set (5 x 100 gm) or the single 100 gm chrome-plated Hangers with Slotted Weights
• Number of sets for each practical batch
• Whether your experiment needs the hanger's own mass counted within the stated load (ask us to confirm)
• The apparatus you will hang it from, so the hook fit can be checked

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM for these Hangers with Slotted Weights 500 gm and makes them at its own licensed factory at Saha, Ambala, Haryana, India, rather than buying them in from a trader. Institutions and dealers get quotations straight from the maker, and extra sets or replacement weights for an existing lab can be requested from the same source; just ask us. The company is a registered MSME enterprise (Udyam UDYAM-HR-01-0003714) and handles export orders under Importer-Exporter Code AAECJ8618A (DGFT). More on the company profile page.

Last updated: 24 September 2026

Hangers with Slotted Weights (Product Code: SCL260/029) is a chrome-plated iron slotted weight with hanger used to apply a small, known load in school physics practicals. It suits lighter experiments where 100 gm is enough, since it is listed as 1 x 100 gm, such as balancing forces on a parallelogram board or pulling a roller up an inclined plane apparatus. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 100 gm Hanger with Slotted Weight Used For?

Many force and equilibrium practicals need only a light, known pull. In the parallelogram-of-forces experiment, weights hang from strings running over pulleys and students compare the resultant with the measured forces; on an inclined plane with roller and pan, a small load balances the roller's pull down the slope. A 100 gm weight gives roughly 0.98 N, a convenient unit for these calculations and for checking a spring balance at the low end of its scale.

The chrome-plated finish is bright and easy to wipe clean, which helps when weights are handled by many students across a term. Hook the hanger securely onto the string loop before letting go, keep the pieces from each bench together so readings stay comparable, and store the weight dry after use.

What to Specify When Ordering

• Whether you need this single 100 gm chrome-plated hanger weight or the 500 gm black-iron set (5 x 100 gm)
• How many pieces each bench needs, for example one per string in a parallelogram-of-forces set-up
• The apparatus or string arrangement it will hang from, so the hook fit can be confirmed

OEM Manufacturer

These chrome-plated Hangers with Slotted Weights are made by ScienceLab, the trading name of Jain Scientific Equipments Private Limited, which is the OEM and produces them at its own licensed factory at Saha, Ambala, Haryana, India. Schools and colleges that standardise on one weight type across their mechanics benches can reorder identical pieces from the manufacturer itself; ask us for repeat quantities. Dealers and importers are quoted on the same factory-direct basis. See the ScienceLab profile for company details.

Fortin Barometer (Product Code: SCL-268/032) is a mercury barometer used to measure atmospheric pressure precisely in school and college physics laboratories. Before each reading the mercury in the cistern is set to a fixed zero called the fiducial point, and the column height is then read on a clear linear scale with a vernier, which makes it a classic teaching item among physics lab instruments. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Fortin Barometer Used For?

A Fortin Barometer shows atmospheric pressure as the height of a mercury column. Because the space above the column has been emptied of air, only the pressure of the atmosphere on the cistern holds the mercury up, which makes it an effective way to teach Torricelli's principle. Labs also use the day's reading when working on gas-law practicals or correcting boiling-point measurements taken with a hypsometer.

To take a reading, turn the adjusting screw until the mercury surface in the cistern just meets the fiducial point, then set the vernier to the top of the mercury column at eye level and add the vernier reading to the main scale value. Note the room temperature with each reading, as precise barometer readings are normally corrected for it. Mount the instrument where students cannot knock it, and follow your institution's mercury-handling rules for any spill.

OEM Manufacturer

Frequently Asked Questions

How does a Fortin Barometer work?
A Fortin Barometer balances atmospheric pressure against a column of mercury. Air is evacuated from the top of the tube and its lower end sits in a mercury cistern, so the height of the column read on the scale indicates the atmospheric pressure.

What is the fiducial point on a Fortin Barometer?
The fiducial point on a Fortin Barometer is the scale zero. Before every reading, the mercury level in the glass at the bottom of the cistern is adjusted to meet it, so each column reading starts from the same reference level.

How precise are Fortin Barometer readings?
The Fortin Barometer uses a vernier adjustment on its clear linear scale for extra reading accuracy. For the vernier least count and scale units of the model you are quoted, please ask us through the contact page.

How should a Fortin Barometer be moved after installation?
To move a Fortin Barometer, turn the adjustment screw until mercury fills the reservoir and the column is about 25 mm from the top of the scale. Lift it off the wall, tilt it gently and lay it flat, then turn the screw further until a small air gap remains in the reservoir.

How should a Fortin Barometer be carried and re-hung?
A Fortin Barometer can be moved without risk of damage as long as it is always carried flat or upside down. To re-hang it on the wall or pillar, reverse the moving procedure step by step before taking the next reading.

Is mercury included with the Fortin Barometer?
How the Fortin Barometer is dispatched, including its mercury, should be confirmed with us before ordering, since transport rules for mercury differ by destination. Ask through the contact page and the details will be stated in your quotation.

Who manufactures the Fortin Barometer?

Plumb Line Level (Product Code: SCL-272/034) is a brass plumb weight, hung on a line, used to establish a true vertical in school and college physics laboratories. Teachers and students use it to check that stands, scales and hanging apparatus are upright and to trace vertical lines in the centre of gravity experiment; the brass body is compact and dense, so it settles steadily. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is a Plumb Line Level Used For?

Gravity pulls the hanging weight straight down, so the line marks the local vertical. In the classic experiment to find the centre of gravity of an irregular lamina, the lamina is hung from a pin, the plumb line is hung from the same pin, and the line is traced on the lamina; repeating this from a second hole gives two lines that cross at the centre of gravity. The same tool checks that Searle's apparatus, a wall-mounted barometer or a vertical meter scale is truly upright before readings begin.

Let the weight come fully to rest before marking, and keep it away from fans and open windows that make it swing. Keep the line free of knots and kinks, since they shift where the weight hangs. Brass does not rust as iron does, though it can tarnish, so an occasional wipe with a dry cloth keeps it tidy.

OEM Manufacturer

The Plumb Line Level is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is the OEM for its own range of physics lab items. It is made at the company's licensed factory at Saha, Ambala, Haryana, India, and schools, colleges, dealers and importers buy it factory-direct, with repeat and bulk orders quoted by the manufacturer itself. Tender and vendor-registration teams can note the company's CIN, U29309HR2020PTC087597, and Factory Licence AMB-ONLINE-CHD-J-414 for its premises at 449, HSIIDC Industrial Area, Saha, Ambala.

Rising Table (Product Code: SCL-276/036) is a height-adjustable laboratory stand used to raise a vessel of liquid to a capillary tube in the surface tension of liquid by capillary rise method. Physics students in senior school and college use it as the base of this surface tension apparatus, and it comes complete with a capillary tube clamp and a side rod attachment. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is a Rising Table Used For?

In the capillary tube experiment, a clean capillary is held vertical in the clamp with its lower end dipping into water in a beaker standing on the rising table. Water climbs the narrow bore to a height that depends on the liquid's surface tension, and a travelling microscope is used to read the meniscus. The side rod attachment is typically used to carry a pointer set just touching the liquid surface, so the table can then be lowered and the microscope sighted on the pointer tip to fix the level of the free surface.

Surface tension is then calculated from the rise height, the bore radius, the liquid's density and the acceleration due to gravity. For steady results, clean the capillary well, since grease spoils the meniscus, wet the bore before the reading, raise or lower the table slowly so the column is not disturbed, and note the water temperature, because surface tension changes with it.

OEM Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) that builds this Rising Table, clamp and side rod set at its own licensed factory at Saha, Ambala, Haryana, India. Labs that need several stations for a practical batch, or a replacement clamp for an existing table, can raise it with the manufacturer directly; ask us.

Double Layered Bronze Pot (Product Code: SCL-284/040) is a double-walled bronze vessel used in school and college physics laboratories, mainly for practical work with liquids and heat. Its two layers of bronze set it apart from ordinary single-walled containers, and teachers choose it where a vessel with a separate inner and outer wall is needed. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is a Double Layered Bronze Pot Used For?

Double-walled vessels are commonly used in heat practicals because the space between the two walls changes how quickly the inner vessel exchanges heat with the room. In a typical Newton law of cooling apparatus set-up, for example, a calorimeter of hot water sits inside a double-walled enclosure so that its surroundings stay at a steady temperature while students record temperature against time. The same idea helps in any demonstration comparing heat loss from shielded and unshielded containers.

Bronze, an alloy based on copper, conducts heat well and stands up to repeated use and cleaning. Dry the pot after use, avoid abrasive scouring that marks the surface, and tell us which calorimeter, lid or thermometer you plan to use with it so we can confirm the fit before you order.

OEM Manufacturer

This Double Layered Bronze Pot comes from Jain Scientific Equipments Private Limited, which trades as ScienceLab and is its OEM (original equipment manufacturer). The pot is made at the company's own licensed factory at Saha, Ambala, Haryana, India, so buyers deal with the maker rather than a trading middleman, and matching pieces for later batches can be requested from the same factory; ask us. Schools, colleges, dealers and importers receive factory-direct quotations. See the ScienceLab profile for company details.

Related Physics Lab Equipment

These heat-practical items are often considered together with a double-walled vessel:

• Apparatus for Newton's Cooling Law — a complete set-up for cooling-curve practicals
• Calorimeter, Copper — an inner vessel for heat and cooling experiments
• Lid (Having Two Holes) — a two-hole lid for a thermometer and stirrer; ask us about fit
• Stop Clock — for timing temperature readings

See the full Physics Lab category for more heat apparatus.

Frequently Asked Questions

What is the Double Layered Bronze Pot made of?
The Double Layered Bronze Pot (code SCL-284/040) is made of bronze and has a double-layered construction, meaning an inner and an outer wall. Bronze is a durable copper-based alloy that conducts heat well.

What is a double layered pot used for in a physics lab?
A double layered pot such as the Double Layered Bronze Pot is typically used in heat practicals, where the space between its walls helps control heat exchange with the room, for example around a calorimeter in cooling experiments.

What size is the Double Layered Bronze Pot?
The dimensions and capacity of the Double Layered Bronze Pot are not listed on this page. Ask us through the contact page, mentioning any calorimeter or lid you want to use with it, and the size will be stated in your quotation.

How should the Double Layered Bronze Pot be cared for?

Electromagnet with Transformer for Sonometer (Product Code: SCL-292/044) is a sonometer accessory used to set a steel sonometer wire vibrating from the AC mains, so students can determine the frequency of the supply in the physics lab. Senior schools and colleges use it for the AC sonometer experiment, and it pairs the electromagnet with its own transformer in one item. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for sonometer work in Indian and overseas labs.

Key Details

What Is the Sonometer Electromagnet Used For?

In the AC sonometer experiment the electromagnet sits close to the steel wire between the two bridges, and the transformer feeds its coil from the AC mains. The alternating field pulls on the magnetic wire twice in every cycle, so the wire is driven at twice the mains frequency. Students move a bridge or change the load until a small paper rider on the wire is thrown off, which marks resonance, then calculate the wire's frequency from its vibrating length, tension and mass per unit length and halve it to get the supply frequency.

The method only works with a magnetic wire such as steel; brass or copper wire will not respond to the electromagnet. Keep the pole close to the wire without touching it, switch off at the mains before adjusting the set-up, and avoid leaving the coil energised between readings so it does not warm up unnecessarily.

What to Specify When Ordering

• Your mains supply voltage and frequency, so we can confirm the transformer suits it
• The sonometer it will be used with, for example a simple or 3-wire pattern
• Whether a sonometer, steel wire and slotted weights should be quoted with it

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM of this Electromagnet with Transformer for Sonometer and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Buyers can put questions on compatibility with their sonometer, replacement parts and repeat orders straight to the manufacturer; ask us. The company holds MSME registration UDYAM-HR-01-0003714, with manufacturing as its major activity, and ships export orders under DGFT Importer-Exporter Code AAECJ8618A. Company background is on the ScienceLab profile page.

Frequently Asked Questions

What does the Electromagnet with Transformer for Sonometer do?
The Electromagnet with Transformer for Sonometer drives a steel sonometer wire into vibration using the AC mains. Students adjust the wire to resonance and use it to determine the frequency of the AC supply in the physics lab.

Why does the sonometer wire vibrate at twice the mains frequency?
With the Electromagnet with Transformer for Sonometer, the magnetic wire is attracted on both the positive and negative half of every AC cycle. It is therefore pulled twice per cycle, so the resonant frequency found is halved to give the mains frequency.

What supply does the Electromagnet with Transformer for Sonometer need?
The input rating of the Electromagnet with Transformer for Sonometer should be confirmed with us for the unit you are quoted. State your local mains voltage and frequency on the contact page so we can check it suits your lab.

Which wire works with the Electromagnet with Transformer for Sonometer?
The Electromagnet with Transformer for Sonometer needs a magnetic wire, such as steel, to act on. Brass, copper or other non-magnetic wires will not respond to the electromagnet, so use a steel wire on the sonometer for this experiment.

Is a sonometer included with the Electromagnet with Transformer for Sonometer?
The Electromagnet with Transformer for Sonometer is an accessory listed separately from the sonometer. If you need both, name the sonometer you want, simple or 3-wire pattern, on the same quotation request.

Tuning Fork Set (Product Code: SCL-294/045) is a set of eight tuning forks of different frequencies used to produce steady reference tones for sound and resonance experiments in school and college physics labs. The forks span 256 Hz to 512 Hz, exactly one octave, and are made of chrome-plated steel with high tensile strength, which makes it a practical tuning fork set for India's school and college sonometer and resonance tube work. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Tuning Fork Set Used For?

A set of forks at different frequencies lets students repeat one experiment at several known frequencies and look for the pattern. On a sonometer, each fork is matched to a vibrating length of wire to show that frequency and resonating length are inversely related; in a resonance tube, forks of different frequencies give different resonance lengths from which the speed of sound in air is worked out. Because the set runs from 256 Hz to 512 Hz, the lowest and highest forks also demonstrate an octave, where one frequency is exactly double the other.

Strike each fork on a rubber pad, never on the bench or another hard object, since knocks can damage the plating and shift the frequency. Hold it by the stem, keep fingers off the prongs while it sounds, and press the stem firmly on the sonometer board when transferring vibrations. Return each fork to the pouch after the practical so the set stays complete.

What to Specify When Ordering

• Number of Tuning Fork Sets, typically one per practical station
• Whether particular individual frequencies are required by your practical scheme (ask us for the eight values in the set)
• Whether a rubber pad for striking the forks should be quoted with each set

OEM Manufacturer

Jain Scientific Equipments Private Limited sells under the ScienceLab name and is the OEM (original equipment manufacturer) of this Tuning Fork Set, which it makes at its own licensed factory at Saha, Ambala, Haryana, India. Schools and colleges that lose or damage a single fork can ask the manufacturer directly about a replacement; ask us about availability. Dealers and importers are quoted factory-direct on the same terms as institutions. Visit the ScienceLab profile page for company information.

Frequently Asked Questions

How many forks are in the Tuning Fork Set?
The Tuning Fork Set (code SCL-294/045) contains eight tuning forks, each of a different frequency, covering 256 Hz to 512 Hz. That gives students several known frequencies for repeat readings in one practical session.

Which frequencies does the Tuning Fork Set include?
The Tuning Fork Set runs from 256 Hz at the lowest to 512 Hz at the highest, with eight forks in total. For the exact frequency marked on each of the eight forks, please ask us through the contact page.

What are the Tuning Fork Set forks made of?
The forks in the Tuning Fork Set are made of chrome-plated steel with high tensile strength. The plating helps protect the steel surface, and careful striking on a rubber pad keeps each fork sounding at its marked frequency.

How should forks from the Tuning Fork Set be struck?
Strike forks from the Tuning Fork Set gently on a rubber pad, holding them by the stem. Never strike them on a bench, metal or glass, because hard knocks can damage the prongs and alter the frequency.

Does the Tuning Fork Set come with storage?
Yes, the Tuning Fork Set is listed with a pouch for keeping the eight forks together. Storing each fork back in the pouch after use protects the plating and makes it easy to check the set is complete.

Rubber Pad (Product Code: SCL-296/046) is a plain, square black rubber pad used in physics laboratories as a soft striking surface for tuning forks. Students need it in sound practicals such as the sonometer and the resonance tube experiment, where a fork must be set vibrating without being knocked against anything hard. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as an accessory to its sound apparatus.

Key Details

What Is a Rubber Pad Used For?

A tuning fork should be excited by striking one prong on something firm but soft. The rubber pad does that job: it sets the prongs vibrating cleanly at the fork's own frequency, without the metallic clang and extra overtones produced by hitting a bench, and without denting the prongs or chipping their plating. Keeping one pad at every sound-practical station saves students from improvising with books or table edges.

The plain surface can also serve as a cushioning mat for small instruments on a hard bench. To keep the rubber in good condition, store the pad flat, keep it away from heaters, oils and solvents that can soften or crack rubber, and wipe it with a damp cloth when it gets dusty.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies the Rubber Pad from Ambala, Haryana, India, as an accessory to the tuning forks and sound apparatus in its physics range. The company sources the pad for laboratory use and can put it on the same quotation as forks, a sonometer or a resonance tube, so a complete sound practical can be ordered from one supplier. More about the company is on the ScienceLab profile page.

Related Physics Lab Equipment

The Rubber Pad is normally ordered with these sound-practical items:

• Tuning Fork Set — eight forks from 256 Hz to 512 Hz to strike on the pad
• Resonance Tube Apparatus — the speed-of-sound practical that uses struck forks
• Sonometer, Simple Pattern — for matching a fork to a vibrating wire
• Tuning Fork — a single fork for individual use

See more items in the Physics Lab category.

Frequently Asked Questions

What is the Rubber Pad used for?
The Rubber Pad (code SCL-296/046) is used to strike tuning forks gently in physics practicals. Hitting a fork on the pad sets it vibrating at its own frequency for sonometer and resonance tube experiments without damaging the prongs.

Why should a tuning fork be struck on a Rubber Pad instead of a bench?
Striking a tuning fork on a Rubber Pad gives a clean tone and protects the fork. Hard surfaces such as benches, metal or glass add unwanted overtones and can dent the prongs or damage plating, which may change the fork's frequency.

What is the Rubber Pad made of?
The Rubber Pad is made of black rubber in a square shape with a plain surface. Store it flat and away from heat, oils and solvents so the rubber stays firm and does not crack.

What size is the Rubber Pad?
The dimensions and thickness of the Rubber Pad are not listed on this page. Please ask us through the contact page and the size will be confirmed in your quotation.

Who supplies the Rubber Pad?
The Rubber Pad is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India, to schools, colleges, laboratory dealers and institutional buyers in India and international markets.

Resonance Tube Apparatus (Product Code: SCL-298/047) is a closed-pipe resonance set-up used to find the speed of sound in air with a tuning fork in school and college physics laboratories. It is built around a 25 mm stainless steel (S.S.) pipe, and students use it in the resonance tube experiment to locate the first and second resonance positions of an air column. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Resonance Tube Apparatus Used For?

The apparatus turns the pipe into an air column closed at the bottom by water and open at the top. A sounding tuning fork is held just above the open end while the length of the air column is slowly changed; at certain lengths the sound suddenly becomes much louder, which is resonance. The first resonance occurs at roughly a quarter wavelength and the second at three quarters, so the speed of sound equals twice the fork frequency multiplied by the difference between the two resonance lengths.

Hold the fork horizontally over the mouth of the tube without touching it, approach each resonance position slowly from above and below, and take several readings with more than one fork. Note the room temperature, because the speed of sound in air rises with temperature. The stainless steel pipe resists rust from the water used in the experiment, but drain and dry it after each session.

What to Specify When Ordering

• Number of Resonance Tube Apparatus units for your practical batches
• Whether a Tuning Fork Set and Rubber Pad should be quoted with each unit
• Which accessories come with the apparatus for your order (ask us to confirm in the quotation)

OEM Manufacturer

The Resonance Tube Apparatus is produced by ScienceLab, the brand of Jain Scientific Equipments Private Limited, which is the OEM (original equipment manufacturer) and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Ordering from the maker means the stainless steel pipe apparatus, the forks and other sound-practical items can be quoted together, and questions about spare parts go directly to the manufacturer; ask us. Institutions, dealers and importers are all quoted factory-direct. Company details are on the ScienceLab profile page.

• Vernier Calliper — to measure the tube bore when estimating end correction

Explore the Physics Lab category for more sound and wave apparatus.

Frequently Asked Questions

What is the pipe of the Resonance Tube Apparatus made of?
The Resonance Tube Apparatus (code SCL-298/047) uses a 25 mm stainless steel (S.S.) pipe. Stainless steel resists rusting from the water that closes the air column, which helps the apparatus last through repeated practical sessions.

How is the speed of sound found with the Resonance Tube Apparatus?
With the Resonance Tube Apparatus, students find the first and second resonance lengths for a tuning fork of known frequency. The speed of sound in air equals twice the fork frequency multiplied by the difference between those two lengths.

What is end correction in the Resonance Tube Apparatus experiment?
End correction allows for the sound antinode forming slightly above the open end of the Resonance Tube Apparatus. Using the difference between the first and second resonance lengths cancels it, and it can also be estimated from the tube's internal radius.

Which tuning forks suit the Resonance Tube Apparatus?
Choose forks for the Resonance Tube Apparatus whose resonance lengths fall within the usable length of the tube; higher frequencies give shorter lengths. Ask us through the contact page for the tube length before selecting forks.

Are tuning forks included with the Resonance Tube Apparatus?
Tuning forks are listed separately from the Resonance Tube Apparatus, for example as the eight-fork Tuning Fork Set. Add them to the same enquiry, and we will confirm in the quotation exactly what comes with the apparatus.

Slinky Spring (Product Code: SCL-300/048) is a steel helical spring used to demonstrate wave motion in school and college physics laboratories. Teachers stretch the compact 75 x 50 mm coil along a bench or floor, where it extends to about 5 metres, so a class can watch pulses travel and reflect. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside its wider physics lab equipment in India.

Specifications

What Is the Slinky Spring Used For?

A slinky spring makes wave behaviour visible on a lab bench. With one end held still and the other moved from side to side, a transverse pulse runs along the coils; pushing the free end forward and back instead produces compressions and rarefactions, the pattern of a longitudinal, sound-like wave. Because a spring can undergo a large elastic deformation and then return to shape, the same coil can be stretched and released many times in one lesson.

Springs of this kind are used widely in mechanical systems and some structural elements, which gives teachers a real-world link for the topic. In class, work on a smooth floor or a long bench so the 5 m stretch does not snag, extend the spring gradually rather than all at once, and collapse it coil by coil after use so it does not tangle.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana. The company supplies this slinky spring together with the mechanics and wave apparatus that schools and colleges buy for their practicals, so a single order can cover several experiments. For vendor registration, the supplying company is Jain Scientific Equipments Private Limited (GSTIN 06AAECJ8618A1ZT, LEI 3358004HRD1JIVXKYX49). More background is on the ScienceLab company profile.

The Slinky Spring (SCL-300/048) is made of steel. A steel coil keeps its elasticity through repeated stretching, which is why it suits classroom demonstrations of wave motion where the spring is pulled out and released many times in one lesson.

How far does the Slinky Spring stretch?
The Slinky Spring extends to about 5 metres when fully stretched, from a size of 75 x 50 mm. That length gives enough room to watch a pulse travel, reflect from a held end and return, so students can observe wave behaviour clearly.

Can the Slinky Spring show transverse and longitudinal waves?
Yes, the Slinky Spring can show both. Moving one end sideways sends a transverse pulse along the coils, while pushing and pulling the end along the length of the spring creates compressions and rarefactions, the pattern of a longitudinal wave such as sound.

How should the Slinky Spring be stored?
Store the Slinky Spring collapsed and dry after easing it back together coil by coil. Avoid overstretching it or letting it tangle, because kinked coils no longer carry a clean pulse and the demonstration loses its clarity.

Who supplies the Slinky Spring?
The Slinky Spring is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company serves schools, colleges, institutions and dealers in India and international markets and can combine this spring with other physics lab items in one order.

What should a quotation request for the Slinky Spring include?
A quotation request for the Slinky Spring should state the product code SCL-300/048, the quantity, the delivery location and any other physics apparatus needed in the same order. Send these details through the ScienceLab contact page to receive a quotation.

Hypsometer (Product Code: SCL-302/049) is a copper steam apparatus used to check the upper fixed point of thermometers and to study boiling points in school and college physics laboratories. It suits thermometry practicals because its steam-jacketed inner tube keeps the thermometer bulb surrounded by steam shielded from room air. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, and offered as thermometry apparatus for schools in India and abroad.

Specifications

What Is the Hypsometer Used For?

In a thermometry practical, water is boiled in the hypsometer and the thermometer under test passes through the lid so that its bulb sits in the rising steam rather than in the water. The steam jacket around the inner tube keeps the thermometer surrounded by steam at a steady temperature, so students can check whether its upper fixed point mark reads correctly. The manometric tube shows whether the steam inside is at the same pressure as the room.

Because the boiling point of water depends on pressure, the same apparatus is used to study boiling points at pressures other than atmospheric, with a barometer reading taken on the day. Fill the vessel with enough water before heating, heat gently until steam leaves the side outlet steadily, and let the thermometer reading settle before recording it.

OEM Manufacturer

The Hypsometer is produced by Jain Scientific Equipments Private Limited, which trades as ScienceLab. As the OEM (original equipment manufacturer), the company makes this copper apparatus at its own licensed factory at Saha, Ambala, Haryana, India, and supplies it factory-direct instead of through a trader.

Schools, colleges, dealers and importers deal with the maker itself, so replacement bungs and repeat orders are handled by the same team; ask us about current availability. Read more on the ScienceLab company profile.

• Apparatus for Newton's Cooling Law — a further heat and temperature experiment

See all heat, mechanics and electricity apparatus in the Physics Lab category.

Frequently Asked Questions

What is the Hypsometer made of?
The Hypsometer (SCL-302/049) is made of copper. Copper conducts heat well and stands up to repeated boiling, so the apparatus can be used for thermometry practicals session after session in school and college physics laboratories.

Why does the Hypsometer have a steam jacket?
The inner tube of the Hypsometer is steam-jacketed so that the thermometer is surrounded by steam shielded from cooler room air. This keeps the temperature around the bulb steady while the upper fixed point or a boiling point is being read.

What does the manometric tube on the Hypsometer do?
The manometric tube on the Hypsometer shows whether the steam pressure inside differs from the outside air pressure. Checking it lets students confirm that the boiling point they read matches the pressure recorded from a barometer.

Is a thermometer included with the Hypsometer?
The listed Hypsometer comprises the copper boiling vessel, steam-jacketed inner tube, lid with tubule and bung, side outlet draining tube and manometric tube; a thermometer is not listed. Confirm the exact scope of supply through the ScienceLab contact page when you request a quotation.

Rubber Cork for Hypsometer (Product Code: SCL-304/050) is a red rubber bung used to seal the thermometer and tube openings of a hypsometer during thermometry experiments in physics laboratories. Lab staff order it as a spare when the original bungs harden, crack or go missing, and it is offered as an assorted lot. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, from its range of physics instruments for schools and colleges.

Key Details

What Is the Rubber Cork for Hypsometer Used For?

A hypsometer depends on tight bungs: one holds the thermometer under test in the lid tubule and another seals the manometric tube in its side tubulure. If a bung is cracked or loose, steam escapes and both the pressure check and the fixed-point reading lose their meaning. These rubber corks replace worn or lost bungs so the apparatus can go straight back into use.

When a hole is needed, bore it with a sharp cork borer of the right size. Wet the thermometer with a little water or glycerine, hold it close to the cork with a cloth and ease it through with a gentle twist; never force glass through a tight hole. Keep spare corks away from heat and oil, which make rubber harden or swell.

What to Specify When Ordering

• The openings the corks must fit: the lid tubule for the thermometer, the manometric tube neck, or both
• The number of corks needed per hypsometer and per lab
• Whether a complete Hypsometer or other physics apparatus should be quoted in the same order

Supplier

Jain Scientific Equipments Private Limited trades as ScienceLab and supplies these rubber corks from Ambala, Haryana, as spares for the physics apparatus it offers schools and colleges. Ordering corks together with the hypsometer keeps a thermometry set complete, and the same enquiry can cover other consumables. Company details are on the ScienceLab company profile.

D Scale for Measuring Angles (Product Code: SCL-308/052) is a large plyboard protractor used to set out and read angles during physics lessons and practicals. With a radius of about 30 cm and markings from 0° to 90° at 15° intervals, it can be read by a whole class and handled easily on the bench. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for mechanics lab equipment buyers in India and abroad.

Specifications

What Is the D Scale Used For?

The D scale works as a demonstration-size protractor. Teachers use it at the front of the room to show how an angle is measured from a baseline, and students use it on the bench to set the angle of an inclined plane, check the tilt of a board or mark directions for force and ray diagrams. The large 15° steps make standard angles quick to set without hunting for fine divisions.

Because it is graduated in 15° steps rather than single degrees, it is meant for setting and demonstrating angles rather than precise measurement; pair it with a handheld protractor when a reading to the nearest degree is needed. Lay the straight edge along the baseline, align the centre with the vertex, and store the plyboard flat and dry so it stays true.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM for the D Scale for Measuring Angles and makes it at its own licensed factory at Saha, Ambala, Haryana, India.

Water Pipe with a Metallic Nozzle (Narrow Opening) (Product Code: SCL-312/054) is a green plastic water pipe with a narrow metal nozzle, used to supply water to apparatus and benches in school physics laboratories. The tubing is lightweight and tough, and resists weathering, tearing, impact and abrasion. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a practical part of a school lab setup in India.

Key Details

What Is the Water Pipe with Metallic Nozzle Used For?

In the physics lab the pipe carries water from a tap to where it is needed: filling containers and reservoirs, rinsing apparatus, or feeding set-ups that need a steady supply. The narrow metal nozzle concentrates the flow into a thin, faster jet, which helps when water must be directed precisely and shows students that the same flow speeds up through a smaller opening.

Push the pipe fully onto the tap or push-to-connect fitting before opening the tap, turn the water on slowly and keep the nozzle pointed away from electrical apparatus. Drain the pipe after use and coil it loosely; it resists weathering and abrasion, but sharp kinks still restrict the flow.

Supplier

Jain Scientific Equipments Private Limited supplies this water pipe under its ScienceLab trading name from Ambala, Haryana. It is offered alongside the physics apparatus that needs a water supply, so schools can source the pipe with the rest of their lab order instead of from a separate hardware shop. More about the company is on the ScienceLab company profile.

Split Cork (Product Code: SCL-314/055) is a cork cut into two halves, used to grip a thread or thin rod in the jaws of a clamp stand in school physics laboratories. Its common use is the simple pendulum experiment, where the thread is held between the halves so the point of suspension stays fixed. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for schools assembling simple pendulum apparatus in India.

Key Details

What Is the Split Cork Used For?

In the simple pendulum experiment, the thread from the bob is passed between the two halves of the split cork and the cork is tightened in the jaws of a clamp stand. The flat faces pinch the thread so the length from the point of suspension to the bob stays constant and the thread does not slip or twist while oscillations are timed.

The same approach holds a thin wire or glass tube gently in a clamp where bare metal jaws would grip too hard. Keep the two halves together as a pair, clamp firmly but not so hard that the thread is cut, and measure the pendulum length from the lower face of the cork.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies split corks from Ambala, Haryana, for schools and colleges putting together pendulum and clamp-stand set-ups. Size details are not given on this listing, so the exact item is confirmed with each quotation. See the ScienceLab company profile for company details.

Related Physics Lab Equipment

The other parts of a simple pendulum set-up:

• Bob/Metallic Sphere (Small) With Hooks — the bob hung from the thread
• Cotton Thread Roll — thread for the pendulum
• Vertical Stand With 3 Clamps — the stand and clamp that hold the split cork
• Stop Clock — timing the oscillations
• Meter Scale 100 cm — measuring the pendulum length

All pendulum and mechanics items are in the Physics Lab category.

Frequently Asked Questions

What is a Split Cork used for in physics?
A Split Cork holds a pendulum thread firmly in a clamp stand. The thread passes between the two halves of the cork, which are then clamped, fixing the point of suspension so the length stays constant while oscillations are timed.

Why use a Split Cork instead of tying the thread to the clamp?
A Split Cork gives a sharp, fixed point of suspension, whereas thread tied around a clamp can slip, twist or swing about a blurred pivot. The fixed point makes the measured length and timed period more consistent between trials.

What size is the Split Cork?
Size details for the Split Cork are not listed on this page. Please ask through the ScienceLab contact page for the dimensions of the current supply, and mention the clamp you use so the cork suits its jaws.

How tightly should the Split Cork be clamped?
Clamp the Split Cork firmly enough that the thread cannot slide, but not so tightly that the cork crumbles or cuts the thread. Then measure the pendulum length from the lower face of the cork to the centre of the bob.

Who supplies the Split Cork?
ScienceLab, the trading name of Jain Scientific Equipments Pvt Ltd in Ambala, Haryana, India, supplies the Split Cork. Schools and dealers in India and international markets usually order it with bobs, thread, stands and stop clocks so the pendulum set-up arrives together.

What does a quotation for the Split Cork need?

Steel Ball (Product Code: SCL-316/056) is a round steel ball of 2.5 cm diameter used for rolling, falling and collision experiments in school physics laboratories. Teachers use it on inclined planes and tracks, and its silver steel surface and compact size make it easy to handle and track by eye. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for mechanics lab equipment needs in India.

Specifications

What Is the Steel Ball Used For?

A steel ball is a simple, dense mass for motion experiments. Rolled down an inclined plane it shows acceleration and the change from potential to kinetic energy; dropped from a measured height it can be timed for free fall; and two balls meeting on a track illustrate momentum transfer. Its round shape lets it roll freely along a guide.

Use a groove or channel to keep the ball on course in rolling experiments, and catch it on a rubber pad or in a tray after a fall so it does not dent benches or floors. Wipe it dry after handling to prevent rust spots, and measuring its diameter with a Vernier calliper makes a quick warm-up exercise.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, Ambala, which supplies this steel ball for school and college mechanics practicals. For vendor registration and export paperwork, the supplying company holds Importer-Exporter Code AAECJ8618A (DGFT) and GSTIN 06AAECJ8618A1ZT. Further background is on the ScienceLab company profile.

Related Physics Lab Equipment

Apparatus used with the steel ball in mechanics practicals:

• Stop Clock — timing rolling or falling motion
• Vernier Calliper — checking the diameter of the ball
• Bob/Metallic Sphere (Small) With Hooks — a hooked sphere for pendulum work

See the Physics Lab category for the full mechanics range.

Frequently Asked Questions

What is the diameter of the Steel Ball?
The Steel Ball (SCL-316/056) has a diameter of 2.5 cm. Students can confirm this with a Vernier calliper as a measurement exercise before using the ball in rolling, falling or collision experiments.

What is the Steel Ball made of?
The Steel Ball is made of steel, silver in colour and round in shape. Steel gives a dense, hard ball that resists denting in collisions and rolls freely along a guide, which suits school mechanics experiments.

Can the Steel Ball be used as a pendulum bob?
The Steel Ball has no hook listed, so it is not set up as a pendulum bob. For pendulum work the Bob/Metallic Sphere (Small) With Hooks is the direct choice; use the steel ball for rolling, falling and collision work.

How should the Steel Ball be stored?
Keep the Steel Ball dry and wipe off fingerprints after use to prevent rust spots. Store it in a tray or box where it cannot roll off shelves, because a falling steel ball can chip floors, benches or glassware.

Who supplies the Steel Ball?
The Steel Ball comes from Jain Scientific Equipments Pvt Ltd (ScienceLab), a supplier in Ambala, Haryana, India. It can be quoted alone or with inclined planes, stop clocks and other mechanics apparatus for schools, colleges and dealers in India and international markets.

Wooden Block (Product Code: SCL-318/057) is a plain, square brown wooden block, 2 cm high, used as the sliding body in friction experiments and as a support or spacer on the physics lab bench. Schools buy it in class quantities for friction and inclined-plane practicals. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, alongside its other mechanics lab equipment.

Specifications

What Is the Wooden Block Used For?

In friction practicals the block rests on a horizontal surface or an inclined plane and is pulled with a spring balance, or by weights hung over a pulley, until it just begins to move. Loading it with slotted masses shows how friction changes with the normal force, and its flat square faces give a steady contact area while its 2 cm height keeps it low and stable.

The block also serves as a spacer under one end of a board or track, a stop at the foot of a ramp, or a rest that raises small apparatus. Keep its faces clean and dry and use the same face when comparing surfaces, so that each trial compares materials rather than dust.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM of this wooden block and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Buying from the manufacturer lets a school or dealer order blocks in class quantities with its friction and inclined-plane apparatus, and repeat orders are handled by the same maker; ask us about quantities.

With a melting point of 60°C and a long-burning character, it is a standard material for school lab heat energy work. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools and colleges.

Specifications

What Is the Paraffin Wax Used For?

The 60°C melting point suits melting-point and cooling-curve experiments: a boiling tube of wax is warmed in a water bath and then left to cool while its temperature is recorded at regular intervals, and the flat part of the curve marks the change of state. In conduction demonstrations, rods coated with wax show how far heat has travelled as the wax melts along them.

The wax is also used to seal joints and corks, coat surfaces and make simple candles for heat and light activities, where its long-burning character helps. Melt it in a water bath rather than over a direct flame, keep molten wax away from open flames, and let spills harden before scraping them off.

Lid (Having Two Holes) (Product Code: SCL-323/060) is a vessel cover with two openings, used to close a calorimeter or similar vessel while a thermometer and a stirrer pass through it in heat experiments. Physics teachers use it to cut heat loss from the liquid surface during calorimetry and cooling practicals. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for use in school heat experiments.

Key Details

What Is the Lid with Two Holes Used For?

In calorimetry and cooling experiments, heat escapes from an open vessel by convection and evaporation. Covering the vessel reduces that loss, while the two holes let a thermometer and a stirrer pass through so the liquid can be stirred and its temperature read without lifting the cover. This keeps results closer to the expected pattern in a Newton law of cooling apparatus or a method-of-mixtures experiment.

Fit the thermometer through a cork in one hole so its bulb hangs clear of the base, keep the stirrer moving freely in the other, and check that the lid sits flat on the rim before heating or mixing begins.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM of this lid and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Schools and dealers ordering heat apparatus can source the lid from the same manufacturer, which keeps replacements simple; ask us about matching sizes.

BI-metallic Sheet (Product Code: SCL-328/062) is a plain square sheet of iron and brass joined together, used to demonstrate the unequal thermal expansion of metals in school physics laboratories. When it is heated, the brass expands more than the iron and the sheet bends, the principle behind thermostats and fire alarms. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, and supplied as physics lab equipment to schools in India and abroad.

Specifications

What Is the Bimetallic Sheet Used For?

Held with tongs and warmed over a flame, the sheet curls with the brass on the outside of the curve because brass expands more than iron for the same rise in temperature; on cooling it returns towards flat. Students see directly that different metals expand by different amounts, and can link the effect to thermostats, fire alarms and flasher switches that use a bimetallic strip to open or close a contact.

Heat the sheet evenly and briefly, hold it only with tongs or an insulated holder, and let it cool on a heatproof surface. Asking the class to predict the direction of bending before revealing which face is brass turns the demonstration into a quick reasoning exercise.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, makes the BI-metallic Sheet as the OEM at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges and importers buy it straight from the manufacturer with the rest of their heat apparatus, and repeat or replacement pieces are handled by the same team; ask us for details. See the ScienceLab company profile.

• Bunsen Burner — heating the sheet evenly
• Crucible & Beaker Tongs — holding the hot sheet safely
• Metal/Steel Sheet (Rectangular) — a single-metal sheet for comparison
• Wax — showing heat conduction along metal surfaces

Browse all heat apparatus in the Physics Lab category.

Frequently Asked Questions

What metals is the BI-metallic Sheet made of?
The BI-metallic Sheet (SCL-328/062) is made of iron and brass joined in a square, plain sheet. Because the two metals expand by different amounts when heated, the sheet bends visibly, which is the effect students observe.

Which way does the BI-metallic Sheet bend when heated?
When heated, the BI-metallic Sheet bends with the brass on the outside of the curve, because brass expands more than iron for the same temperature rise. On cooling it straightens again, so the demonstration can be repeated.

Where is the bimetallic principle used?
The effect shown by the BI-metallic Sheet is used in thermostats, fire alarms, electric iron cut-outs and flasher switches, where a bimetallic strip bends to open or close an electrical contact as the temperature changes.

How do I heat the BI-metallic Sheet safely?
Hold the BI-metallic Sheet with tongs or an insulated holder and heat it evenly over a burner flame for a short time. Let it cool on a heatproof surface before handling, since both metals stay hot after the flame is removed.

Who manufactures the BI-metallic Sheet?
The BI-metallic Sheet is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges and importers order it directly from the manufacturer, usually together with other heat apparatus.

What size is the BI-metallic Sheet?

Horizontal Friction Table (Product Code: SCL-329/063) is a mechanics apparatus used to demonstrate the composition of a force and to determine the coefficient of friction between different materials in school and college physics laboratories. Teachers use it as a compact friction experiment kit: a wooden base carries a hinged inclined plane and a pulley, and the plane can be set at any angle between 24 and 45 degrees. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Friction Table Used For?

In a typical practical, the metal roller or a sliding block rests on the plane, a thread runs over the pulley to the scale pan, and weights are added to the pan until motion just begins. Comparing the loads needed at different settings lets students calculate the coefficient of limiting friction and resolve the weight of a body into components along and perpendicular to the plane.

Because the plane is hinged, the same table also supports angle-of-repose work: the plane is raised until a sample starts to slide and the angle is read, for materials whose angle falls within the 24–45° range. Keep the plane and sliding faces clean and dry, and tap the table lightly before each reading so that static friction does not give erratic results. It is a practical piece of mechanics lab equipment for school and undergraduate courses.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer (OEM) of this friction table. The table is produced and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, so schools, colleges and dealers buy directly from the maker rather than through a trader. Requests for a replacement roller or scale pan, and repeat orders, are handled by the manufacturer itself — just ask us. Read more on the ScienceLab company profile.

Apparatus for Newton's Cooling Law (Product Code: SCL-333/065) is a heat-transfer apparatus used to study how a hot body loses heat to its surroundings in school and college physics laboratories. Students use this Newton's law of cooling apparatus to record and compare cooling curves, with two copper calorimeters held in a trough inside an outer tank. It is produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Newton's Cooling Apparatus Used For?

Newton's law of cooling states that the rate at which a body loses heat is proportional to the difference between its temperature and that of its surroundings. With this apparatus, hot water is poured into a calorimeter, a thermometer is passed through the wooden top, and the temperature is noted at regular intervals as it cools; plotting temperature against time gives the cooling curve.

Having two copper calorimeters lets a class cool two liquids, or two quantities of the same liquid, side by side under identical surroundings — the basis of finding the specific heat of a liquid by the method of cooling. Stir gently before each reading, keep the set away from draughts and fans, and start timing only once the thermometer reading is falling steadily. It is a dependable thermometry apparatus for calorimeter lab practicals.

OEM Manufacturer

ScienceLab is the brand name of Jain Scientific Equipments Private Limited, and the company is the OEM for this cooling-law apparatus. Each set is made at its own licensed factory at Saha, Ambala, Haryana, India, and dispatched factory-direct to schools, colleges, institutions and dealers. If your department later needs a replacement calorimeter or wooden top, ask the manufacturer directly. Background on the company is on the ScienceLab profile page.

Related Physics Lab Equipment

A cooling-law practical also needs timing, temperature measurement and a way to heat water. These items fit that workflow:

• Stop Clock — times the interval between temperature readings.
• Immersion Thermometer — reads the liquid temperature through the holes in the wooden top.
• Calorimeter, Copper — a spare copper calorimeter for extra samples.
• Beaker (Glass) — for heating and pouring the water or liquid under test.

See more heat and mechanics apparatus in the Physics Lab category.

Frequently Asked Questions

What does the Apparatus for Newton's Cooling Law consist of?
The Apparatus for Newton's Cooling Law consists of two copper calorimeters resting inside a trough, which stands in an outer tank. The outer tank has a wooden top with two holes, so a thermometer can sit in each calorimeter while cooling readings are taken.

Are thermometers included with the Newton's cooling apparatus?
Thermometers are not listed as part of the Apparatus for Newton's Cooling Law; the wooden top only provides two holes to hold them. Mention the thermometers you need in your enquiry and we will confirm what can be added to the quotation.

Why does the Newton's cooling apparatus have two calorimeters?
The Apparatus for Newton's Cooling Law has two copper calorimeters so two samples can cool side by side under the same conditions. This makes it straightforward to compare cooling curves, for example water against another liquid when finding specific heat by the method of cooling.

Who manufactures the Apparatus for Newton's Cooling Law?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Apparatus for Newton's Cooling Law as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Quotations, replacement parts and repeat orders are therefore handled by the manufacturer itself, without a trading intermediary.

How should the copper calorimeters be looked after?
After each practical, empty and dry the copper calorimeters of the Apparatus for Newton's Cooling Law and store the set with the wooden top in place. Avoid abrasive cleaners and dents, because a smooth, even surface gives more consistent cooling curves from class to class.

What information is needed for a quotation?
For a quotation on the Apparatus for Newton's Cooling Law, send the number of sets, whether thermometers or a stop clock should be included, and the delivery address through the contact page. Institutions and dealers in India and international markets can request quantity quotations.

Students connect a resistor across the unknown-resistance sockets, switch on, and turn the potentiometer to raise the voltage in steps, noting the voltmeter and milliammeter readings each time. A straight-line graph of voltage against current passing through the origin verifies Ohm's law, and its slope gives the resistance.

Because the circuit is already wired and drawn on the front panel, practical time goes into measuring and graphing rather than connecting loose meters, which suits large classes. Keep the current within the 500 mA range, switch off before changing resistors, and use 4 mm leads for secure connections.

What to Specify When Ordering

• Number of units required for your laboratory.
• Whether the step-down transformer and lead wire should be included, and the mains supply available in your laboratory.
• The resistors you plan to test, so the 5 V and 500 mA meter ranges suit them.

Wheatstone Bridge Apparatus (Product Code: SCL-339/068) is a slide-wire bridge used to find an unknown resistance by balancing it against a known one in school and college physics laboratories. It has nine heavy lock-type brass terminals, removable copper binding pieces across the end gaps and a pencil jockey, so it forms a Wheatstone bridge experiment kit once a galvanometer, cell and resistance box are added. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Wheatstone Bridge Used For?

The bridge compares an unknown resistance with a known value taken from a resistance box. A cell drives current through the wire, a galvanometer is connected between the junction of the two resistances and the jockey, and the jockey is moved along the wire until the galvanometer shows no deflection; at that null point, the ratio of the two wire lengths equals the ratio of the resistances.

Students also use it to find the resistivity of a wire's material and to check the laws of resistances in series and parallel. Tighten each lock-type terminal fully, press the pencil jockey lightly rather than dragging it along the wire, and choose a known resistance that brings the balance point near the middle of the scale for the best precision.

Frequently Asked Questions

What is the Wheatstone Bridge Apparatus used to measure?
The Wheatstone Bridge Apparatus is used to measure an unknown resistance by comparing it with a known resistance at the null point of a galvanometer. The same set-up is used to find the resistivity of a wire and to verify series and parallel combinations of resistances.

How does the Wheatstone Bridge Apparatus keep end errors small?
On the Wheatstone Bridge Apparatus, the wire runs along the top of a wooden metre scale and is securely clamped to brass end strips, so end errors are negligible. The nine lock-type brass terminals also keep connection resistance to a minimum.

What accessories are needed with the Wheatstone bridge?
The Wheatstone Bridge Apparatus comes with a pencil jockey. To perform the experiment you also need a galvanometer, a cell, a plug key, a resistance box and connecting leads, all of which ScienceLab can include in the same quotation on request.

Who manufactures the Wheatstone Bridge Apparatus?
The Wheatstone Bridge Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), which is the OEM and produces it at its own licensed factory in Saha, Ambala, Haryana, India. Buyers deal with the manufacturer directly for quotations and replacement parts.

How should the bridge wire be looked after?
Keep the wire of the Wheatstone Bridge Apparatus clean and straight, and press the pencil jockey lightly at each test point instead of sliding it under pressure. Scraping thins the wire locally, which changes its resistance per unit length and spoils balance-point readings.

Can the Wheatstone Bridge Apparatus be ordered in bulk?
Yes. The Wheatstone Bridge Apparatus can be quoted in lab-set quantities for schools, colleges, dealers and importers across India and international markets. Send the number of units and any accessories through the contact page, and the quotation will come directly from the manufacturer in Ambala.

Meter Bridge (Product Code: SCL-341/069) is a one-metre slide-wire bridge used to determine unknown resistance and the resistivity of a wire in school and college physics laboratories. A single 1 m length of 24 SWG bare constantan wire runs along a rule divided in centimetres and millimetres on a powder-coated aluminium extrusion, and a jockey is supplied. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Meter Bridge Used For?

The meter bridge works on the Wheatstone bridge principle: with a known resistance on one side and the unknown on the other, the jockey is tapped along the wire until a galvanometer reads zero, and the balancing length gives the unknown value. Classes use it to find the resistance and specific resistance of a wire, to verify series and parallel combinations, and to compare two resistances.

Measuring the wire's diameter with a screw gauge alongside the balancing lengths lets students calculate resistivity, a standard physics practical at senior secondary level and a routine item in any meter bridge lab. Tap the jockey rather than sliding it, interchange the known and unknown resistances and average the results, and keep the constantan wire free of kinks.

What to Specify When Ordering

• Number of meter bridges needed, usually one per student group.
• Whether a galvanometer, resistance box, plug key and cell should be quoted with it.
• Spare jockeys or replacement constantan wire, if your laboratory keeps them in stock.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known to customers as ScienceLab, is the OEM for this meter bridge and produces it at its own licensed factory at Saha, Ambala, Haryana, India, rather than buying it in from a trader. Institutions and dealers can order factory-direct, and questions about replacement wire or jockeys go straight to the manufacturer. Read about the company on the ScienceLab profile page.

Related Physics Lab Equipment

For resistance and resistivity practicals on the meter bridge, laboratories usually add:

• Moving Coil Galvanometer — centre-zero detector for locating the balance point.

• Screw Gauge — measures wire diameter for resistivity calculations.
• Constantan Wire — sample wire for resistance and resistivity experiments.
• Jockey — a spare sliding contact for student sets.

The Physics Lab category lists further bridge and circuit apparatus.

Frequently Asked Questions

What wire is used on the Meter Bridge?
The Meter Bridge uses a single 1 m length of 24 SWG bare constantan wire. Constantan is chosen for bridge wires because its resistance changes very little with temperature, which keeps balancing lengths steady throughout a practical session.

How does the Meter Bridge minimise end errors?
On the Meter Bridge, the constantan wire is clamped to brass plates by a system designed to make contact at the exact ends of the scale. This leaves virtually no margin for end errors, although interchanging the resistances and averaging remains good practice.

Is a jockey included with the Meter Bridge?
Yes, the Meter Bridge is supplied with a jockey. A galvanometer, resistance box, cell, plug key and connecting leads are needed to complete the circuit, and they can be added to the same quotation on request.

What kind of terminals does the Meter Bridge have?
The Meter Bridge has heavy-duty 4 mm socket terminals on its terminating strips, so it accepts standard 4 mm banana-plug leads. This allows quick, firm connections to the galvanometer, resistance box and cell during class practicals.

Who manufactures the Meter Bridge?
The Meter Bridge is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers receive quotations straight from the manufacturer.

Potentiometer, 10 wire (Product Code: SCL-343/070) is a ten-metre slide-wire potentiometer used to compare the emf of cells and measure internal resistance in college and senior school physics laboratories. Ten 1 m lengths of 24 SWG bare constantan wire run over a centimetre- and millimetre-divided scale on a powder-coated aluminium extrusion, giving a long wire for fine balance readings. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 10-Wire Potentiometer Used For?

A steady driver cell sends current through the full length of wire, so the potential falls uniformly along it; a test cell connected through a galvanometer and the jockey is then balanced at the point where no current flows. Because the test cell supplies no current at balance, the potentiometer measures its true emf, which an ordinary voltmeter cannot do.

Standard experiments include comparing the emfs of two primary cells with a two-way key, finding the internal resistance of a cell using a resistance box, and calibrating an ammeter or voltmeter. A rheostat in the driver circuit sets the potential gradient; keep it unchanged through a set of readings and tap the jockey only lightly. These tasks make it a core item for potentiometer lab practicals.

What to Specify When Ordering

• Number of potentiometers needed per laboratory.
• Whether a driver supply, rheostat, two-way key and galvanometer should be quoted with it.
• Any spare jockeys for student batches.

OEM Manufacturer

The 10-wire potentiometer is produced by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. The company is a registered MSME enterprise (Udyam UDYAM-HR-01-0003714) and ships export consignments under Importer-Exporter Code AAECJ8618A issued by the DGFT. Universities, schools and importers therefore buy direct from the manufacturer, which also handles repeat orders. See the company profile for more.

Frequently Asked Questions

How long is the wire on the Potentiometer, 10 wire?
The Potentiometer, 10 wire carries ten separate 1 m lengths of 24 SWG bare constantan wire, giving 10 m of wire in total. The long wire lowers the potential gradient, so each centimetre of balancing length represents a smaller voltage and readings are finer.

What experiments is the 10-wire potentiometer used for?
The Potentiometer, 10 wire is used to compare the emfs of two cells, to find the internal resistance of a primary cell and to calibrate voltmeters and ammeters. All of these rely on the null-deflection principle, so the cell under test supplies no current at balance.

What else is needed to use the Potentiometer, 10 wire?
The Potentiometer, 10 wire is supplied with a jockey. A complete set-up also needs a steady driver supply, a rheostat, a galvanometer, a plug or two-way key, cells under test and 4 mm connecting leads; ScienceLab can quote these together.

How does the potentiometer keep end errors small?
The constantan wires of the Potentiometer, 10 wire are clamped to brass plates by a system that makes electrical contact at the exact ends of the scale. This leaves virtually no margin for end errors when balancing lengths are read off the centimetre and millimetre divisions.

Who manufactures the Potentiometer, 10 wire?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Potentiometer, 10 wire as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Quotations for institutions, dealers and importers come directly from the manufacturer, which also supports repeat supply.

Resistance Box (Product Code: SCL-345/071) is a plug-type standard resistance used to insert known values from 1 to 1000 ohm into circuits in school and college physics laboratories. Constantan coils connect across 1/2 inch brass blocks inside a teak wood case, and removing a brass plug brings the matching coil into the circuit. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Resistance Box Used For?

A plug-type resistance box provides known resistances for circuits that measure voltage, current and resistance. In meter bridge and Wheatstone bridge experiments it forms the known arm, while in Ohm's law and potentiometer work it limits current or acts as the shunt when finding a cell's internal resistance.

Each brass plug shorts out one coil; pulling it out adds that coil's value, so the resistance in circuit is the sum of the unplugged coils. Seat plugs with a gentle twist to keep contact resistance low, and before switching on, check that the right plugs are out — with every plug inserted the box offers practically zero resistance. This makes it a basic resistance box for lab benches in India and abroad.

What to Specify When Ordering

• Range: this box covers 1 to 1000 ohm; a separate higher-range model is listed for galvanometer-conversion work.
• Quantity per laboratory or per student group.
• Companion items such as galvanometers, meter bridges or plug keys.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM that makes this resistance box at its own licensed factory at Saha, Ambala, Haryana, India. The finished boxes go factory-direct to schools, colleges, dealers and importers, and requests for replacement plugs are handled by the manufacturer itself. Visit the company profile to learn more.

More resistance and circuit apparatus is in the Physics Lab category.

Frequently Asked Questions

What is the range of this Resistance Box?
This Resistance Box covers 1 to 1000 ohm using constantan coils selected by brass plugs. For experiments that need several thousand ohms, such as converting a galvanometer into a voltmeter, the Resistance Box 1-5000 Ohm Range is the more suitable choice.

How do you read the value on a plug-type Resistance Box?
On a plug-type Resistance Box, the value in circuit is the sum of the coils whose plugs have been removed. Inserting a plug shorts its coil through the brass block, so with all plugs in place the box adds practically no resistance.

What materials is the Resistance Box made of?
The Resistance Box uses constantan coils, 1/2 inch brass blocks, brass plugs and a deluxe-quality teak wood case. Constantan keeps the coil values steady as the room warms, and the brass blocks give low-resistance plug contacts.

Who manufactures the Resistance Box?
The Resistance Box is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), which is the OEM and produces it at its licensed factory in Saha, Ambala, Haryana, India. Schools, colleges and dealers can order direct from the maker and ask it for replacement plugs.

Is a calibration certificate available for the Resistance Box?
The standard listing for the Resistance Box does not include a calibration certificate. If your laboratory or tender needs one, mention it in your enquiry through the contact page, and we will tell you what documentation can be arranged before you order.

How should the Resistance Box be maintained?
Keep the Resistance Box closed and dry when not in use, clean plugs and blocks with a soft dry cloth if readings become unsteady, and seat each plug with a gentle twist. Avoid oiling the contacts, because oil films raise contact resistance and cause errors.

Resistance Box 1-5000 Ohm Range (Product Code: SCL-347/072) is a brass plug-type resistance box used to add known resistances of up to 5000 ohm to circuits in college and senior school physics laboratories. Its wider range suits galvanometer and voltmeter-conversion practicals where a lower-range box is not enough, with constantan coils housed in a teak wood case. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 5000 Ohm Resistance Box Used For?

The higher range is useful when a galvanometer must be converted into a voltmeter, which needs a large resistance in series with its coil, and when finding a galvanometer's resistance and figure of merit by the half-deflection method. It also serves as the known arm in bridge circuits and as a current limiter in potentiometer set-ups.

To set a value, remove the plugs whose coils add up to the resistance you need and leave the rest firmly seated. Start experiments with a high value unplugged and reduce it gradually, which protects sensitive meters from sudden large currents. It is a useful addition to the physics lab instruments in any senior practical room.

What to Specify When Ordering

• Confirm that the 1 to 5000 ohm range suits your experiments; a lower-range Resistance Box is also available.
• Quantity required per laboratory.

Rheostat 30 Ohm (Product Code: SCL-349/073) is a sliding-contact variable resistor used to control current or divide voltage in school and college physics circuits. With a total resistance of 30 ohm, it suits low-resistance circuits where current must be adjusted in fine steps, and its three terminals let it work as either a rheostat or a potentiometer. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 30 Ohm Rheostat Used For?

Connected through one end terminal and the slider terminal, it acts as a variable resistor that sets the current in experiments such as Ohm's law, meter bridge and ammeter calibration. Connected across a supply using both end terminals, with the output taken from the slider, it becomes a potential divider that gives a smoothly variable voltage.

A 30 ohm winding changes resistance in small increments, so it is well matched to low-voltage cell circuits and to the driver circuit of a wire potentiometer. Check the maximum current marked on the slider before connecting, start with the slider at the high-resistance end, and move it gradually. It is a practical rheostat for lab benches in schools and colleges.

What to Specify When Ordering

• Resistance value: this model is 30 ohm; a separate Rheostat model is also listed.
• The current your circuit needs, so it can be checked against the rating marked on the slider.
• Quantity per laboratory.

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM of this 30 ohm rheostat and builds it at its own licensed factory at Saha, Ambala, Haryana, India. Because the maker sells direct, buyers get quotations and repeat supplies from the factory itself instead of a middleman, and can ask it about replacement sliders. More about the company is on the ScienceLab profile page.

Related Physics Lab Equipment

A current-control circuit built around this rheostat typically also uses:

• Rheostat — another rheostat model for circuits needing a different value.
• Ammeter — reads the current being adjusted.
• Battery Eliminator 12 Volt — a DC source for the circuit.
• One Way Key — switches the circuit on only while readings are taken.

Other circuit components are listed in the Physics Lab category.

Frequently Asked Questions

One Way Key (Product Code: SCL-353/075) is a plug key used to open and close a single electric circuit in school and college physics practicals. It has two brass blocks with 4 mm terminals on a moulded plastic base, and one accurately tapered brass plug with a fluted plastic top bridges the gap between them with negligible contact resistance. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the One Way Key Used For?

The one way key acts as the on/off switch in nearly every current-electricity practical, from Ohm's law and meter bridge circuits to potentiometer driver circuits. Inserting the plug completes the circuit; removing it breaks the circuit so that no current flows while connections are being changed.

Good practice is to insert the key only while taking a reading and remove it straight afterwards, which stops cells running down and resistance wires heating up. Give the plug a slight twist as it goes in for a firm seat, and keep the tapered surfaces clean. It is a basic item among the physics lab instruments on a student bench.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which sells under the ScienceLab name, is the OEM of this one way key and produces it at the company's own licensed factory at Saha, Ambala, Haryana, India. Plug keys are usually ordered in bench quantities, and buying factory-direct keeps supply and repeat orders straightforward; spare plugs can be requested straight from the manufacturer.

Frequently Asked Questions

What does the One Way Key include?
The One Way Key has two brass blocks, each fitted with a 4 mm bakelite terminal and mounted on a moulded plastic base, plus one accurately tapered brass plug with a fluted plastic top that fits the hole between the blocks.

How does the One Way Key make good electrical contact?
The tapered brass plug of the One Way Key wedges firmly into the matching hole between the two brass blocks, giving negligible contact resistance. A slight twist while inserting it keeps the contact reliable throughout a practical session.

When should a one way key be used instead of a two way key?
Use the One Way Key when a single circuit needs to be switched on and off, such as a cell and resistance loop. A two way key is chosen when one common point must be connected to either of two circuits, as when comparing two cells.

Who manufactures the One Way Key?
The One Way Key is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Schools and dealers buying keys in bench quantities deal directly with the manufacturer.

It is supplied with two accurately tapered brass plugs with fluted plastic tops, which seat between brass blocks fitted with 4 mm terminals on a moulded plastic base. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Two Way Key Used For?

In a potentiometer experiment to compare the emfs of two cells, the two way key lets students switch the galvanometer branch from one cell to the other without rewiring: one plug brings the first cell into circuit, and moving to the other plug brings in the second. The same switching is used when comparing resistances or choosing between two branches of a circuit.

Insert only one plug at a time unless the experiment specifically needs both paths closed. Keep the tapered plugs and holes free of dust and tarnish, and store the plugs with the key so they are not lost between classes. It is standard physics practical equipment for potentiometer and bridge set-ups.

What to Specify When Ordering

• Quantity per laboratory or per potentiometer set.
• Whether One Way Keys are also required for the same benches.
• Any spare plugs to keep in the laboratory store.

OEM Manufacturer

Frequently Asked Questions

How many plugs come with the Two Way Key?
The Two Way Key comes with two accurately tapered brass plugs, each with a fluted plastic top. Each plug closes one of the two paths, so the common terminal can be connected to either circuit as the experiment requires.

What is a two way key used for in a potentiometer experiment?
In emf comparison with a potentiometer, the Two Way Key connects the galvanometer and jockey branch to one cell or the other. Students balance each cell in turn simply by moving the plug, without disturbing any other connections.

How does the Two Way Key keep contact resistance low?
The Two Way Key uses accurately tapered brass plugs that fit snugly into holes between brass blocks, giving negligible contact resistance. Clean, dry plugs and a gentle twist when inserting them help maintain that low resistance from one practical to the next.

Moving Coil Galvanometer (Product Code: SCL-357/077) is a centre-zero DC meter used to detect small currents and locate null points in bridge and potentiometer experiments in school and college physics laboratories. It has a 30-0-30 scale, comes with a stand, and has diode protection against overload up to 12 V DC. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Moving Coil Galvanometer Used For?

Because the pointer rests at the centre, the meter shows both the presence and the direction of a small current. As a galvanometer for school laboratories, its main job is null detection in meter bridge, Wheatstone bridge and potentiometer practicals: students move the jockey until the pointer returns to zero, then read the balancing length.

It is also used to demonstrate electromagnetic induction, where pushing a magnet into a coil and pulling it out swings the pointer first one way and then the other. Tap the jockey briefly rather than holding it down, and add a high resistance in series for the first trials so the pointer stays on scale.

What to Specify When Ordering

• Confirm that the 30-0-30 scale and the listed 200 microampere sensitivity suit your experiments.
• Quantity required, usually one per bridge or potentiometer set.
• Whether resistance boxes, jockeys or plug keys should be quoted with it.

Supplier

Jain Scientific Equipments Private Limited trades as ScienceLab and supplies this moving coil galvanometer from Ambala, Haryana, to schools, colleges, institutions and dealers in India and international markets. The company sources it for customers who want galvanometers, bridges and resistance boxes from a single supplier, so one quotation can cover the whole electricity bench. Company background is on the ScienceLab profile.

Related Physics Lab Equipment

A galvanometer is rarely used on its own. These items complete typical null-detection circuits:

• Meter Bridge — the bridge in which the galvanometer finds the balance point.
• Jockey — the sliding contact tapped along the bridge wire.
• Resistance Box 1-5000 Ohm Range — provides high series resistance to protect the meter.
• Galvanometer 50-0-50mV — an alternative meter with a different range.

More meters and circuit apparatus are in the Physics Lab category.

Frequently Asked Questions

What scale does the Moving Coil Galvanometer have?
The Moving Coil Galvanometer has a centre-zero 30-0-30 scale, so the pointer can deflect either way to show the direction of current. This centre-zero layout is what makes it suitable as a null detector in bridge and potentiometer experiments.

What sensitivity is listed for the Moving Coil Galvanometer?
The Moving Coil Galvanometer is listed with a sensitivity of 200 microampere. The listing does not make clear whether this is per division or for full-scale deflection, so please confirm the figure you need through the contact page before ordering.

Is the Moving Coil Galvanometer protected against overload?
Yes. The Moving Coil Galvanometer has diode protection against overload up to 12 V DC, which helps protect the movement when a jockey is pressed far from the balance point. A series resistance during first trials is still recommended.

Can the Moving Coil Galvanometer be used with AC?
The Moving Coil Galvanometer is a DC instrument, but it is described as suitable as an indicator in slow AC, where the pointer can follow a slowly alternating current. It is not intended for measuring mains-frequency AC values.

Who supplies the Moving Coil Galvanometer?
The Moving Coil Galvanometer is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, India. The company supplies it to schools, colleges, dealers and importers in India and international markets, and can quote it together with meter bridges, jockeys and resistance boxes.

Ebonite Rod (Product Code: SCL-363/080) is a round black ebonite rod used to produce static charge by friction in school and college physics laboratories. Rubbed with fur or wool, it picks up a negative charge, which makes it a standard partner for electroscopes in electrostatics demonstrations; rods are offered in different diameters. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is the Ebonite Rod Used For?

Ebonite is a hard vulcanised rubber and a good insulator, so charge produced on its surface by rubbing stays there long enough to be studied. Students rub the rod with fur or wool and bring it near small pieces of paper, a suspended pith ball or the disc of a gold leaf electroscope to show attraction, repulsion and charging by contact or induction.

Pairing it with a glass rod rubbed with silk shows that two kinds of charge exist, because the two charged rods attract each other. Electrostatic experiments work best in dry air, so wipe the rod clean and dry before use and avoid touching the rubbed end. It is basic physics lab equipment for electrostatics lessons in schools across India.

What to Specify When Ordering

• The diameter you need, since rods are offered in different diameters.
• The length required, as it is not stated in the listing.
• Quantity, and whether rubbing cloths or an electroscope should be quoted with it.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies ebonite rods from its base in Ambala, Haryana, to schools, colleges, institutions and dealers in India and international markets. Ordering the rod together with electroscopes and other electrostatics items means one supplier and one quotation for the whole set. Find out more on the company profile.

Related Physics Lab Equipment

Electrostatics lessons combine charging rods, rubbing materials and a detector. Items used alongside the ebonite rod:

• Gold Leaf Electroscope — detects and compares the charge on the rod.
• Friction Rod, Glass/Brass, 300mm — a glass rod for producing the opposite charge.
• Friction Cloth, Cotton — a cloth for rubbing charging rods.
• Friction Rod, Perspex — another insulating rod for comparing charging behaviour.

See other electrostatics apparatus in the Physics Lab category.

Frequently Asked Questions

What is the Ebonite Rod made of?
The Ebonite Rod is made of ebonite, a hard black vulcanised rubber, and is round in shape. Ebonite is a good electrical insulator, which is why the rod holds the charge produced on it by rubbing during electrostatics experiments.

What charge does an Ebonite Rod acquire when rubbed?
An Ebonite Rod rubbed with fur or wool becomes negatively charged, because electrons transfer from the fur to the ebonite. A glass rod rubbed with silk becomes positively charged, so the two are used together to show like and unlike charges.

Which diameters of Ebonite Rod are available?
The Ebonite Rod is offered in different diameters, but the listing does not give specific sizes or lengths. Tell us the diameter and length you prefer through the contact page, and we will confirm what can be supplied with your quotation.

Who supplies the Ebonite Rod?
The Ebonite Rod is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), based in Ambala, Haryana, India. The company supplies it to schools, colleges, institutions and dealers in India and international markets, together with electroscopes and other electrostatics apparatus.

Why do experiments with the Ebonite Rod sometimes fail?
Experiments with the Ebonite Rod work poorly in humid weather, because a thin film of moisture lets the charge leak away. Wipe the rod dry, use a dry rubbing cloth, and perform the demonstration away from open windows, kettles or other sources of steam.

Can the Ebonite Rod be ordered in class quantities?
Yes, the Ebonite Rod can be quoted in class quantities for schools, colleges and dealers. Send the number of rods, preferred diameter and delivery location through the contact page to receive a quotation from ScienceLab.

A plug pushes into its socket and pulls out cleanly, which saves practical time compared with clamping bare wire under screw terminals.

Using red for the positive side and black for the negative side makes circuit checks faster for teachers and helps students connect meters with the correct polarity — a simple habit that suits physics practical equipment for CBSE and state-board labs. Keep the current within the 15 A maximum, pull on the plug body rather than the cable, and store the leads loosely coiled so the flexible conductor is not kinked.

What to Specify When Ordering

• How many leads you need in black and how many in red.
• That your meters, keys and power supplies accept 4 mm banana plugs.
• The lead length you prefer, as length is not stated in our listing.

Connecting Wire (Product Code: SCL-367/082) is a double cotton covered (DCC) copper wire used to make circuit connections in school and college physics laboratories. Lab assistants cut it to length from a 500 g quantity to join cells, keys, meters and resistance apparatus, while the cotton covering insulates each run. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among the lab consumables it offers for physics practicals.

Specifications

What Is DCC Connecting Wire Used For?

In the electricity section of a physics practical, DCC connecting wire links the cell, plug key, rheostat, ammeter, voltmeter and resistance wire in Ohm’s law, meter bridge and potentiometer experiments. Students cut a short piece for each connection, strip the cotton from the ends, brighten the copper with sand paper and tighten it firmly under each terminal.

Because the cotton layers insulate the wire, DCC copper is also handy for simple coil-winding activities such as a small demonstration solenoid, which makes it a useful stock item in school physics lab equipment in India. Keep connections short and tight to reduce contact resistance, trim loose strands, and store the reel in a dry cupboard since cotton absorbs moisture.

What to Specify When Ordering

• The number of 500 g quantities your laboratory needs.
• The wire gauge or diameter you prefer, as it is not stated in our listing.
• Whether you also need wire cutters and sand paper for preparing the ends.

Voltmeter (Product Code: SCL-369/083) is a DC voltmeter with a 0–15 V range used to measure the potential difference between two points of a circuit in physics laboratories. Schools, colleges, universities and research labs use it as a bench meter for Ohm’s law, cell and resistance readings. The Voltmeter is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its physics lab instruments.

Specifications

What Is a Voltmeter Used For?

A voltmeter reads the potential difference across a resistor, a cell or any other component, so it is the partner to the ammeter in almost every electricity practical. In the Ohm’s law experiment, for example, students read the voltage across the resistance wire for several rheostat settings and plot it against current to find the resistance.

Always connect the meter in parallel with the component, with its positive terminal towards the higher-potential side, and check that the circuit supply stays within the 0–15 V DC range. Choosing a supply that places readings in the upper part of the scale improves reading accuracy, and noting the scale’s least count before starting helps students record values correctly.

What to Specify When Ordering

• That a 0–15 V DC range suits the circuits in your practical syllabus.
• The number of voltmeters required, usually one per workbench.
• Whether you also need a matching ammeter, rheostat and connecting leads.

OEM Manufacturer

The Voltmeter is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab, acting as the original equipment manufacturer (OEM). It is made at the company’s own licensed factory at Saha, Ambala, Haryana, and supplied factory-direct to schools, colleges, universities, dealers and importers rather than through a trader. ScienceLab is a registered MSME (Udyam UDYAM-HR-01-0003714), and export orders are shipped under Importer-Exporter Code AAECJ8618A issued by the DGFT. Read more on the company profile.

• Banana Plug Connectors Leads — flexible leads for wiring the meter into the circuit.

Explore the complete Physics Lab category for other meters and electricity apparatus.

Frequently Asked Questions

What range does the Voltmeter measure?
The Voltmeter measures DC voltage from 0 to 15 V. That range covers the low-voltage circuits built from cells or a lab DC supply in school and college practicals, such as Ohm’s law, cell and resistance experiments.

How is the Voltmeter connected in a circuit?
The Voltmeter is always connected in parallel, across the component whose potential difference you want to read, with its positive terminal on the higher-potential side. Connecting it in series with the rest of the circuit would block the current and give a misleading reading.

Can the Voltmeter measure AC voltage?
No, the Voltmeter is listed as a DC instrument with a 0 to 15 V range, so it is intended for direct-current circuits only. For alternating-current measurements, ask us through the contact page which meter would suit your experiment before ordering.

Who manufactures the Voltmeter?
The Voltmeter is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own factory at Saha, Ambala, Haryana, India. Orders, spare-part questions and repeat supplies are handled by the manufacturer itself, without a trader in between.

Is a calibration certificate available with the Voltmeter?
Calibration certificate availability for the Voltmeter should be discussed with us before you order. Mention the requirement through the contact page, and what can be provided will be stated clearly in your quotation so there is no uncertainty at delivery.

What should a Voltmeter quotation request include?

Ammeter (Product Code: SCL-371/084) is a moving-coil DC ammeter with a 0–5 A range used to measure the current flowing in circuits during school and college physics practicals. It stands on a square-based desk stand with lock-type terminals and is specified to an accuracy of ±2.0% of full-scale deflection. The Ammeter is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Moving Coil Ammeter Used For?

The ammeter is placed in series in a circuit so that the whole current passes through it, which makes it essential for Ohm’s law, series and parallel resistance and rheostat current-control experiments. Its 0–5 A range handles the larger currents drawn by low-resistance circuits, while a milliammeter is the better choice for very small currents.

As a staple of physics lab equipment for schools in India, it should be wired with its positive terminal towards the positive side of the supply and never connected straight across a cell. Because the ±2.0% accuracy is quoted on full scale, readings in the upper part of the dial are proportionally more precise, so adjust the rheostat to bring the needle well up the scale.

What to Specify When Ordering

• That a 0–5 A DC range suits your experiments, or whether a milliammeter is also needed.
• The number of ammeters required for your workbenches.
• Any matching voltmeters, rheostats, keys or leads to include in the same quotation.

OEM Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, and this Ammeter is one of the meters the company builds itself, as OEM, at its factory in Saha, Ambala, Haryana, India. Meters leave the factory directly for schools, colleges, dealers and importers, so questions about replacement parts or repeat batches go straight to the maker — just ask us. Company details are on the ScienceLab profile.

Related Physics Lab Equipment

Apparatus normally wired into the same circuit as the ammeter:

• Voltmeter — reads the potential difference while the ammeter reads current.
• Milliammeter — a lower-range meter for currents in milliamperes.
• Rheostat 30 Ohm — adjusts the circuit current to bring readings up the scale.
• One Way Key — switches the circuit on only while readings are taken.
• Resistance Box — provides known resistances for current measurements.

The Physics Lab category lists the remaining meters and circuit apparatus.

Frequently Asked Questions

What are the range and accuracy of the Ammeter?
The Ammeter reads DC current from 0 to 5 A with a stated accuracy of ±2.0% of full-scale deflection (F.S.D.). Because the error is quoted on the full scale, readings taken in the upper part of the scale are relatively more precise than readings near zero.

How should the Ammeter be connected in a circuit?
The Ammeter must be connected in series so that the whole circuit current passes through it, with its positive terminal towards the positive side of the supply. Never connect it directly across a cell or power supply, as the meter’s very low resistance would allow a damaging current.

What type of movement does the Ammeter use?
The Ammeter uses a moving-coil movement designed for direct current, so the needle deflects in proportion to the current flowing through the coil. Moving-coil meters respond to DC only, which is why the Ammeter should not be connected to an AC supply.

How is the Ammeter mounted on the bench?
The Ammeter comes on a desk stand with a square-shaped base and lock-type terminals. The stand keeps the meter steady and upright on the workbench, and the lock-type terminals hold connecting wires or leads securely while students take their readings.

Who manufactures the Ammeter?
The Ammeter is manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct, so quotations and follow-up questions are handled by the manufacturer rather than a trader.

Can the Ammeter be ordered for a whole laboratory?
Yes, the Ammeter can be ordered in bulk for school and college laboratories, dealers and tender supplies in India and international markets. Share the quantity, the delivery location and any matching voltmeters or rheostats, and the manufacturer will quote for the complete set.

Milliammeter (Product Code: SCL-373/085) is a DC current meter with a 0–500 mA range used to measure small circuit currents in education, laboratory and scientific work. It is fully enclosed in a sturdy plastic housing, has colour-coded binding posts and a zero adjustment, and is listed with an accuracy of ±2.5%. The Milliammeter is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is a Milliammeter Used For?

A milliammeter reads currents that are too small to show clearly on an ampere-range meter, such as the current through an LED, a semiconductor diode or a high resistance. In school and college practicals it is wired in series with the component, so students can see how the current changes as they vary the supply or the resistance.

Before each session, set the needle to zero with the zero adjustment, then match the colour-coded binding posts to the polarity of the supply. Include a series resistance when building a new circuit so the current stays within 500 mA, and increase the supply gradually while watching the needle.

What to Specify When Ordering

• That a 0–500 mA DC range suits your experiments, or whether a 0–5 A ammeter is also needed.
• The number of meters needed for your workbenches.
• Any leads, resistance boxes or components to be quoted alongside.

Supplier

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, supplies this milliammeter from Ambala, Haryana, as part of its work as a physics instruments supplier in India.

Frequently Asked Questions

What range does the Milliammeter cover?
The Milliammeter covers 0 to 500 mA DC. It is intended for small circuit currents, such as those through LEDs, diodes or high resistances, where an ampere-range meter would show only a small movement of the needle.

How accurate is the Milliammeter?
The Milliammeter is listed with an accuracy of ±2.5%. For the most reliable values, set the needle to zero with the zero adjustment before use and choose circuit values that bring the reading well up the scale rather than near zero.

Does the Milliammeter have a zero adjustment?
Yes, the Milliammeter features a zero adjustment, so the needle can be reset to zero before a practical begins. Checking zero at the start of each session removes a common source of error when students record small currents.

What is the Milliammeter housing made of?
The Milliammeter is fully enclosed within a sturdy plastic housing and has colour-coded binding posts. The closed case protects the movement from dust and handling, and the colour coding helps students connect the meter with the correct polarity.

Who supplies the Milliammeter?
The Milliammeter is supplied by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab and is based in Ambala, Haryana, India. It is offered to schools, colleges, dealers and importers across India and international markets with other physics lab apparatus.

Is a calibration certificate available for the Milliammeter?

jockey (Product Code: SCL-374/086) is a pencil-type sliding contact used to locate the balance point along the wire in Wheatstone bridge and potentiometer experiments in physics laboratories. Students hold it by its insulated handle and touch its plated brass contact to the wire, while a plated brass terminal with a 4 mm socket links it to the galvanometer. The jockey is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Pencil Jockey Used For?

On a meter bridge or Wheatstone bridge, the jockey is connected through the galvanometer and tapped at points along the bridge wire until the galvanometer shows no deflection; that null point gives the balancing length used to calculate an unknown resistance. On a potentiometer, the same technique finds the balancing lengths for comparing the EMFs of two cells or measuring a cell’s internal resistance.

This makes the jockey an essential accessory for meter bridge lab work in India and for every potentiometer practical. Press it gently and briefly, lift it, then move to the next point — dragging a pressed jockey scrapes the wire and changes its resistance per unit length. Hold it only by the insulated handle and keep the brass tip clean for a reliable contact.

What to Specify When Ordering

• The number of jockeys needed, usually one per bridge or potentiometer.
• That your galvanometer leads use 4 mm plugs to fit the socket terminal.
• Whether a meter bridge, potentiometer or galvanometer should be quoted with it.

OEM Manufacturer

The jockey is produced by Jain Scientific Equipments Private Limited, trading as ScienceLab, at its own licensed factory in Saha, Ambala, Haryana, where the company is the original equipment manufacturer (OEM) of its bridge and potentiometer accessories. Because it comes straight from the maker, schools, colleges, dealers and importers can add it to bridge orders and ask us directly about replacement pieces or repeat quantities. Learn more on the company profile.

Apparatus the jockey is used with during balance-point experiments:

• Meter Bridge — the bridge wire on which the jockey finds the null point.
• Wheatstone Bridge Apparatus — for resistance measurement using the same balance method.
• Potentiometer, 10 wire — long-wire apparatus where the jockey locates balancing lengths.
• Moving Coil Galvanometer — shows the zero deflection at the balance point.
• Banana Plug Connectors Leads — 4 mm leads to join the jockey to the galvanometer.

Frequently Asked Questions

What is the jockey used for?
The jockey is a pencil-type sliding contact used to find the balance, or null, point on the wire of a Wheatstone bridge or potentiometer. It links the wire to the galvanometer, and the point where the galvanometer shows no deflection gives the balancing length.

How does the jockey connect to the circuit?
The jockey connects through a plated brass terminal fitted with a 4 mm socket, so a lead with a 4 mm plug can join it to the galvanometer. The plated brass contact at its tip then touches the bridge or potentiometer wire wherever a reading is needed.

Why does the jockey have an insulated handle?
The insulated handle lets students hold the jockey without their hand touching the conducting parts, which keeps readings steady and avoids stray contact. It also gives a comfortable pencil-style grip for placing the contact precisely along the wire.

How should the jockey be used to protect the bridge wire?
Press the jockey gently and briefly onto the wire, lift it, and move to the next point instead of dragging it while pressed. Scraping the contact along the wire wears it unevenly and changes its resistance per unit length, which spoils later readings.

Who manufactures the jockey?
The jockey is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to schools, colleges, dealers and importers in India and international markets.

Can the jockey be ordered as a spare for existing bridges?
Yes, the jockey can be quoted on its own as a spare for existing meter bridge, Wheatstone bridge or potentiometer setups, or together with new apparatus. Tell us the quantity and confirm that your leads use 4 mm plugs when you request a quotation.

Leclanche Cell (Product Code: SCL-376/087) is a primary cell apparatus used to provide and study a chemical source of EMF in school and college physics practicals. It consists of a zinc rod of 12.5 mm diameter and a charged porous pot of 150 x 60 mm (height x diameter) with terminals, giving an EMF of about 1.4 V. The cell is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Leclanche Cell Used For?

The Leclanche cell is a standard item of physics practical equipment for CBSE and state-board labs, where students compare its EMF with that of a Daniell cell on a potentiometer. It also shows how a classic wet primary cell works: the zinc rod forms the negative electrode, while the charged porous pot holds the positive electrode and its depolarising mixture.

To set it up, the zinc rod and porous pot are placed in the cell’s electrolyte and connected by their terminals. A Leclanche cell polarises if it supplies current for long periods, so it suits intermittent use — close the circuit with a key only while taking readings, and let the cell rest between trials.

What to Specify When Ordering

• The number of Leclanche cells needed for your practical groups.
• Whether you also need an outer container and ammonium chloride for the electrolyte.
• Any companion cell and potentiometer for EMF-comparison experiments.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM of this Leclanche Cell and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers buy it direct from the manufacturer, and repeat orders or replacement zinc rods and porous pots can be discussed with us directly. For vendor registration, the company’s details are GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. Read more on the company profile.

Related Physics Lab Equipment

Items used with the Leclanche cell in EMF experiments:

• Deniel Cell — a Daniell-type cell whose EMF is compared with the Leclanche cell.
• Potentiometer, 10 wire — measures the EMF by the null method without drawing current.
• Ammonium Chloride 99% — the chemical traditionally used for the cell’s electrolyte.
• jockey — locates the balance point on the potentiometer wire.
• Voltmeter — for quick checks of the cell’s terminal voltage.

See the Physics Lab category for more cells and electricity apparatus.

Frequently Asked Questions

What EMF does the Leclanche Cell give?
The Leclanche Cell gives an EMF of about 1.4 V. That value makes it a useful known source in potentiometer practicals, where students compare its EMF with that of another primary cell such as a Daniell cell.

What are the parts of the Leclanche Cell?
The Leclanche Cell consists of a zinc rod of 12.5 mm diameter and a charged porous pot measuring 150 x 60 mm (height x diameter), fitted with terminals. The zinc rod and the porous pot form the two electrodes of the cell.

Are an outer jar and electrolyte included with the Leclanche Cell?
Our listing for the Leclanche Cell describes the zinc rod and the charged porous pot with terminals. Whether an outer container or ammonium chloride for the electrolyte is included should be confirmed through the contact page, and it will be stated in your quotation.

Why is the Leclanche Cell measured with a potentiometer?
A potentiometer measures the Leclanche Cell’s EMF at the balance point, where no current is drawn from the cell. This matters because a Leclanche cell polarises when it delivers current for long periods, so a null method gives a truer value than a loaded reading.

How should the Leclanche Cell be stored between practicals?
Store the Leclanche Cell clean and dry: take the zinc rod and porous pot out of any electrolyte, rinse and dry the zinc, and keep the parts in a cool cupboard. The working life of the charged pot depends on use and storage, so ask us about replacements.

Who manufactures the Leclanche Cell?
The Leclanche Cell is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to schools, colleges, dealers and importers in India and international markets.

What Is a Daniell Cell Used For?

In this cell the copper vessel acts as the positive electrode in copper sulphate solution, while the zinc rod stands in the porous pot as the negative electrode; the pot keeps the two solutions apart but lets ions pass. Crystals resting on the perforated shelf keep the copper sulphate solution saturated as the cell works, which is why a Daniell cell holds a steady EMF.

Teachers use it as a reference cell on the potentiometer, for comparing its EMF with a Leclanche cell, and for demonstrating how chemical energy becomes electrical energy. After each session, lift the zinc rod out on its wooden cap, rinse the porous pot, and empty and dry the copper vessel so the parts last longer.

What to Specify When Ordering

• The number of cells needed for your practical groups.
• Whether copper sulphate crystals or other electrolyte chemicals should be quoted with the cells.
• Connecting leads with 4 mm plugs to suit the socket terminals.

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, makes this cell as the OEM, with the copper vessel, porous pot, zinc rod and terminals made and assembled at the company’s own licensed factory at Saha, Ambala, Haryana, India.

Sand Paper (Product Code: SCL-382/090) is an abrasive cloth sheet used to remove rust and corrosion and for metal sanding work in school and college laboratories. Its extra-sharp abrasive particles cut quickly, which makes it handy for cleaning wire ends, terminals and metal parts before physics practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside its school lab equipment in India.

Key Details

What Is Sand Paper Used For?

In electricity practicals, sand paper removes the covering and oxide film from the ends of connecting wires and enamelled coil wire, so that each joint makes clean metal-to-metal contact. It also brightens tarnished terminals and cell electrodes, and takes surface rust off iron stands, clamps and metal sheets used elsewhere in the lab.

Cut a sheet into small strips so each group has its own piece, fold a strip over the wire end and draw the wire through gently until the copper shines. Avoid heavy rubbing on thin or calibrated resistance wires, wipe away the metal dust afterwards, and keep unused sheets flat and dry in a drawer.

What to Specify When Ordering

• The number of sheets your laboratory needs.
• The grit or grade you prefer, as it is not stated in our listing.
• The sheet size, if your practical work needs a particular size.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies this sand paper from Ambala, Haryana, India, so that labs can order the small consumables for circuit work together with their apparatus. Schools, colleges, dealers and importers in India and international markets can add it to any physics lab enquiry. You can read about the company on its profile page.

Electromagnet for Demo (Product Code: SCL-385/091) is a U-shaped demonstration electromagnet used to show how an electric current produces magnetism in school and college physics classes. Its iron core of circular section carries two enamelled copper coils joined in series, with an armature and carrying hook for lifting demonstrations, and it operates on 3–6 V DC. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Demonstration Electromagnet Used For?

When the coils are connected to a low-voltage DC supply, the iron core becomes magnetised and pulls the armature across both poles; loads hung from the carrying hook show how firmly it holds. Switching the current off releases the armature at once, which makes the point that an electromagnet’s magnetism lasts only while current flows — a core lesson for any magnetism experiment kit in India.

Teachers also use it with a compass to identify the poles, reverse the supply to show the poles swapping, and sprinkle iron filings on card to reveal the field. Keep the supply within 3–6 V DC, switch on through a key only while demonstrating so the coils do not overheat, and add loads gradually.

What to Specify When Ordering

• The number of electromagnets needed for demonstrations or student groups.
• Whether cells or a DC supply within 3–6 V should be quoted with them.
• Any keys, leads, compasses or iron filings for the same lesson.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), which builds this electromagnet as the OEM. Production takes place at the company’s licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414), and units go factory-direct to schools, colleges, dealers and importers. Ask us directly about replacement armatures or repeat quantities, and see the company profile for more.

• Dry Cell (Rechargeable) 1.5 V — cells in series can supply a voltage within the operating range.
• One Way Key — switches the coil current on only while demonstrating.

The Physics Lab category has more magnetism and electricity apparatus.

Frequently Asked Questions

What voltage does the Electromagnet for Demo need?
The Electromagnet for Demo operates on 3–6 V DC. A few cells in series or a low-voltage DC supply set within that range will magnetise the core, and staying within the range protects the coils from overheating during a lesson.

How are the coils of the Electromagnet for Demo arranged?
The Electromagnet for Demo has two coils of enamelled copper wire, one wound on each arm of its U-shaped iron core, and the coils are joined in series. This arrangement makes the two arm ends act as opposite poles, like a horseshoe magnet.

What are the armature and hook of the Electromagnet for Demo for?
The armature is the iron bar that the Electromagnet for Demo attracts across its two poles, and the carrying hook lets you hang loads from it. Adding loads step by step shows students how strongly the electromagnet holds while current flows.

How can the Electromagnet for Demo show that its magnetism is temporary?
Connect the Electromagnet for Demo through a key, let it hold the armature, then open the key: the armature drops as soon as the current stops. Reversing the supply leads and testing the arm ends with a compass also shows the poles changing.

Who manufactures the Electromagnet for Demo?
The Electromagnet for Demo is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to buyers in India and international markets.

What should an Electromagnet for Demo quotation request include?

Convex Mirror (Product Code: SCL-392/094) is a round, spherical glass mirror used to study how a diverging mirror forms virtual, diminished images in school and college optics practicals. It has a 50 mm diameter and comes in focal lengths of 15 cm and 25 cm, with optically worked, highly polished glass and ground edges. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Convex Mirror Used For?

A convex mirror spreads reflected light outwards, so it always forms a virtual, erect and diminished image — the same principle as a vehicle’s rear-view mirror. In the lab, students compare its images with those of plane and concave mirrors and, in senior classes, find its focal length with the help of a convex lens on an optical bench.

Having two focal lengths lets teachers match the mirror to the lens and bench length available, which keeps it a flexible item of physics lab equipment in India. Hold the mirror only by its ground edges, keep the polished face free of fingerprints, and store each mirror separately in a padded box.

What to Specify When Ordering

• The focal length you need: 15 cm or 25 cm.
• How many mirrors of each focal length are required.
• The mounting or holder needed to use the mirror on your optical bench.

OEM Manufacturer

The Convex Mirror comes from Jain Scientific Equipments Private Limited, which trades as ScienceLab and manufactures its school optics range as the OEM at its own factory in Saha, Ambala, Haryana, India. Ordering from the maker lets schools, dealers and importers combine both focal lengths in one quotation and return to the same source for repeat quantities. More about the company is on its profile page.

Frequently Asked Questions

What focal lengths are available for the Convex Mirror?
The Convex Mirror is available with focal lengths of 15 cm and 25 cm, both on a 50 mm diameter mirror. State which focal length you need, or how many of each, when you request a quotation so the order matches your practical method.

What size is the Convex Mirror?
The Convex Mirror is round with a diameter of 50 mm. It is made of spherical, optically worked glass with ground edges and a highly polished surface, giving a clear reflected image for student optics experiments.

What kind of image does the Convex Mirror form?
The Convex Mirror always forms a virtual, erect and diminished image, whatever the object distance. Because that image cannot be caught on a screen, the mirror’s focal length is usually found with the help of a convex lens on an optical bench.

How is the focal length of the Convex Mirror measured?
First form a real image with a convex lens, then place the Convex Mirror between the lens and that image and move it until the image retraces its own path. The distance from the mirror to the image position is then its radius of curvature, twice the focal length.

How should the Convex Mirror be cleaned and stored?
Clean the Convex Mirror with a soft lens tissue or cloth, holding it only by its ground edges, and store it in a padded box away from other glassware. Although it is listed as chemical and heat resistant, the polished surface should be kept free of scratches.

Who manufactures the Convex Mirror?
The Convex Mirror is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to schools, colleges, dealers and importers in India and international markets.

Concave Mirror (Product Code: SCL-394/095) is a round converging mirror used to form real images and measure focal length in school and college physics practicals. The 50 mm diameter mirror is available in 15 cm and 25 cm focal lengths and is made of spherical, optically worked glass with ground edges and a highly polished face. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Concave Mirror Used For?

Students first estimate the focal length by focusing the image of a distant window onto a screen and measuring the distance to the mirror. They then find it accurately by the u–v method on an optics bench, as practised in Indian schools, removing parallax between the real image and a needle and plotting the results.

The mirror also shows how the image changes as the object moves: real and inverted beyond the focus, enlarged and erect inside it — the principle behind shaving mirrors and torch reflectors. Because it concentrates light, never point it at the Sun, and hold it by the ground edges to keep the polished face clean.

What to Specify When Ordering

• Which focal length you need: 15 cm or 25 cm.
• The quantity required in each focal length.
• Whether an optical bench or mirror mounting should be quoted with the mirrors.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and makes this Concave Mirror as the OEM at its own licensed factory in Saha, Ambala, Haryana, India, so buyers deal with the maker for quotations, repeat quantities and mixed focal-length orders. The company is registered as an MSME enterprise under Udyam number UDYAM-HR-01-0003714 and holds Importer-Exporter Code AAECJ8618A from the DGFT for export consignments. See the company profile for details.

Frequently Asked Questions

What focal lengths does the Concave Mirror come in?
The Concave Mirror comes in two focal lengths, 15 cm and 25 cm, each on a 50 mm diameter mirror. The shorter focal length keeps every reading well inside a one-metre optical bench, while the longer one spreads readings out for easier measurement.

How do students find the focal length of the Concave Mirror?
For a quick estimate, focus the image of a distant window onto a screen with the Concave Mirror and measure the mirror-to-screen distance. For an accurate value, use the u–v method on an optical bench, removing parallax between the image and a needle.

What images can the Concave Mirror form?
The Concave Mirror forms real, inverted images when the object is beyond its focus, and these can be caught on a screen. With the object between the focus and the mirror, it gives an enlarged, erect virtual image, as in a shaving mirror.

What is the Concave Mirror made of?
The Concave Mirror is made of spherical, optically worked glass with ground edges and a highly polished surface, in a round shape. It is listed as chemical and heat resistant, although the polished face should still be protected from scratches.

Is it safe to use the Concave Mirror in sunlight?
Take care when using the Concave Mirror outdoors, because it concentrates light at its focus and can burn skin or paper. Never let students look at the Sun in the mirror, and use a distant building or window as the object for focal-length estimates.

Who manufactures the Concave Mirror?
The Concave Mirror is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to schools, colleges, dealers and importers in India and international markets.

Convex Lens (Product Code: SCL-396/096) is a round, spherical glass lens used to converge light and form real images in school and college physics laboratories. Students use it to find focal length and trace image formation, and it is offered in exact focal lengths of 10 cm, 15 cm and 20 cm with a 2 inch diameter. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its optics lab equipment range.

Specifications

What Is the Convex Lens Used For?

The convex lens is the heart of the focal-length practical. Students first focus the image of a distant window or tree on a screen to get a rough value, then mount the lens on an optical bench and record object and image distances to calculate f from the lens formula. Moving the object from beyond 2F to inside F shows how the image changes from real and inverted to virtual and magnified.

The choice between the 10 cm, 15 cm and 20 cm versions depends on bench length and class level: a short focal length keeps images within a small bench, while a longer one spreads the distances out for easier measurement. Hold the lens by its ground edge, clean the polished faces with lens tissue, and keep it in a padded box so the surfaces stay scratch-free, as with all school physics lab equipment.
