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.

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).

Law of Parallelogram Apparatus (Grave Sand Apparatus) (Product Code: SCL218/09) is a force board used to verify the parallelogram law of vector addition of forces in school and college physics labs. 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.

Weight Box (Physical) (Product Code: SCL52522/011) is a boxed set of chrome-plated brass masses used with a physical balance to weigh objects and to apply known loads in school physics experiments. The masses run from 1 g up to 200 g, covering the everyday weighing of solids in practical classes. 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.
