Physics Lab Equipment

Dual Range Ammeter (Product Code: SLE/PHY/01A) is a moving-coil DC ammeter used to measure circuit current in school and college physics laboratories. Students and lab technicians choose between its 0–1 A and 0–5 A ranges, both read on a single 60 mm scale, so one bench meter covers low- and higher-current experiments. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Dual Range Ammeter Used For?

The meter is connected in series to read the direct current flowing in practical circuits: verifying Ohm’s law with a rheostat and voltmeter, comparing currents in series and parallel branches, checking the current in a potentiometer or meter bridge circuit, and monitoring current during electrolysis. As a core piece of physics lab equipment in India, it sits beside the power supply in most electricity practicals.

Start on the 0–5 A range whenever the current is unknown, then move to the 0–1 A range for a more readable deflection. Check that the pointer rests on zero and use the zero adjustment before each session, connect positive to the positive socket, and never place the meter directly across a supply without a load, as that would drive excessive current through the movement.

Ammeter Voltmeter (Product Code: SLE/PHY/02) is an analogue dual-purpose meter used to measure DC current and DC voltage in school and college electricity practicals. A slide selector switches between amps and volts, bringing in the internal shunting automatically, while four ranges on each function run from 100 µA to 5 A and from 100 mV to 50 V. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges and laboratory dealers.

Specifications

What Is the Ammeter Voltmeter Used For?

One instrument covers both readings that most DC practicals need. Set the slide to amps and connect the meter in series to measure current, from the microamp level of a high-resistance circuit up to 5 A for lamps and heating coils; slide to volts and connect it in parallel to read potential difference from 100 mV to 50 V. Teachers choosing an ammeter voltmeter for school labs in India use it for Ohm’s law, internal-resistance and cell-emf experiments.

Choose the highest range first and step down until the needle gives a clear reading. Reset the pointer with the front zero screw before each session, and never connect the meter in series while set to volts or across a supply while set to amps. A bench that must read current and voltage at the same moment needs two meters, so plan quantities per bench accordingly.

Apparatus Air Track Light Gate (Product Code: SLE/PHY/03) is an air-cushion linear track with photo light gates and a timer, used to study motion under virtually frictionless conditions in school and college mechanics labs. One to four carts ride on the air supplied by the blower, so teachers can run collision, momentum and acceleration experiments with electronic timing. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Air Track with Light Gates Used For?

With friction almost removed, the air track lets students test Newton’s laws and conservation principles with results that sit close to theory. Typical sessions include measuring velocity and acceleration as a cart passes the light gates, pulling a cart with a falling mass over an end pulley to relate force and acceleration, setting up incline runs, and colliding two carts to compare momentum before and after impact. That makes it a central item of mechanics lab equipment in India for senior secondary and undergraduate courses.

Level the track carefully before each run, since a slight tilt adds an unwanted acceleration. Switch the blower on before placing carts on the track and lift them off before switching it off, so cart and track surfaces do not rub. Load the attachable weights evenly to keep carts running straight, and fit the spring bumpers when students are studying impact forces at the ends.

What to Specify When Ordering

• The number of complete air track sets required for your laboratory
• How many carts you plan to run together (the apparatus allows one to four)
• Whether to add the Apparatus Air Track Part Kit of spare vehicles, buffers and catapults

OEM Manufacturer

This air track is produced by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is the OEM (original equipment manufacturer) of the apparatus. It is made and assembled at the company’s own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader, and is supplied factory-direct to schools, colleges, universities and dealers. Spare carts, bumpers and other replacement parts can be requested from the manufacturer itself; ask us. See our company profile for more.

Apparatus Air Track Part Kit (Product Code: SLE/PHY/04) is a set of replacement parts and vehicles used to keep an air track running for collision, momentum and motion experiments in school and college physics labs. It supplies two heavy vehicles and one light vehicle with a 2:1 mass ratio, plus buffers, catapults and consumables such as plasticine, thread and elastic bands. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Air Track Part Kit Used For?

The kit replaces parts that wear out or go missing from a busy air track and adds the items needed for classic collision work. The 2:1 mass ratio between heavy and light vehicles lets students predict and check velocities after a collision. Magnetic buffers can give repelling, nearly elastic interactions, while a needle meeting plasticine in a holder can make two vehicles stick together for an inelastic collision; catapults with elastic bands launch vehicles at repeatable speeds.

Keeping one kit per track is a practical way for schools and colleges to hold lab equipment spare parts in India, so a lost buffer or a worn elastic band does not stop a practical. Store the plasticine wrapped, keep the needles in a labelled container, and check the nylon thread for fraying before it is used to tow or hang masses.

What to Specify When Ordering

• The number of part kits required (for example, one per air track)
• Which air track the kits will serve, so compatibility can be confirmed

Apparatus Bar & Gauge (Product Code: SLE/PHY/05) is a heat-expansion demonstrator used to show that a solid grows when heated and shrinks when cooled, in school and college physics classes. An iron bar 108 mm long and 12.7 mm in diameter just fits the cut-out and hole of a brass gauge when cold, and stops fitting once heated. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Bar and Gauge Apparatus Used For?

The demonstration takes a few minutes and needs only a flame. At room temperature, students check that the bar slides lengthways into the cut-out and passes endways through the hole. The bar is then heated in a burner flame and tried again: it no longer enters either opening, showing that both its length and its diameter have increased. As it cools, or is dipped in cold water, it fits once more, proving the change is reversible.

Because a length gauge and a diameter gauge share one brass plate, the apparatus shows linear expansion and expansion in cross-section in the same lesson, a natural lead-in to the coefficient of linear expansion and to everyday cases such as gaps in railway lines. It is a staple of the physics practical equipment CBSE and state-board schools use when teaching thermal properties of matter. Hold the bar only by its wooden handle while heating, rest it on a heat-proof mat afterwards, and let students handle the gauge only once it has cooled.

OEM Manufacturer

The Apparatus Bar & Gauge comes from Jain Scientific Equipments Private Limited, trading as ScienceLab, which is the OEM (original equipment manufacturer) of this item. It is manufactured at the company’s licensed factory at Saha, Ambala, Haryana, India, and reaches schools, colleges, science dealers and importers factory-direct. Questions about repeat orders or a replacement gauge go straight to the maker; just ask us. More on our company profile.

• Bunsen Burner — the heat source for warming the iron bar
• Expansion Of Liquids Apparatus — extends the topic from solids to liquids

Browse the full Physics Lab Equipment range for more heat apparatus.

Frequently Asked Questions

What are the dimensions of the Apparatus Bar & Gauge?
The Apparatus Bar & Gauge is about 225 mm long overall. Its iron bar measures 108 mm in length and 12.7 mm in diameter, and the brass gauge measures 150 × 38 mm, with a cut-out and a hole sized to the cold bar.

How does the Apparatus Bar & Gauge show expansion?
With the Apparatus Bar & Gauge, the cold iron bar just fits the gauge’s cut-out lengthways and passes through its hole endways. After heating it fits neither, showing expansion in length and diameter; once cooled it fits again, showing contraction.

What heat source is needed for the Bar & Gauge demonstration?
The Apparatus Bar & Gauge only needs a flame that can heat the iron bar for a short time, such as a Bunsen burner or a spirit lamp. Hold the bar by its wooden handle throughout and place it on a heat-proof surface afterwards.

What materials are the bar and gauge made of?
In the Apparatus Bar & Gauge the bar is iron and the gauge is brass, with the bar mounted on a support rod fitted with a wooden handle. The wooden handle keeps the user’s hand away from the heated metal during the demonstration.

Who manufactures the Apparatus Bar & Gauge?
The Apparatus Bar & Gauge is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its licensed factory at Saha, Ambala, Haryana, India, and is supplied factory-direct to schools, colleges and dealers.

Can the Apparatus Bar & Gauge be ordered in class sets or for export?

Apparatus Collision 2 Dimension (Product Code: SLE/PHY/06) is a curved-track ball collision apparatus used to study how momentum and energy change in elastic and inelastic collisions in school and college physics labs. A support on its fixed base holds a target ball at the right height for a centre-to-centre impact, and a pin with three holes gives a repeatable release height. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the 2D Collision Apparatus Used For?

The apparatus is set at the edge of a bench so that balls leaving the base fall to the floor as projectiles. Students first release the incident ball alone from one of the pin positions and mark where it lands, then place the target ball on the support and repeat. Because every ball leaves from the same height, the horizontal distance to each landing mark is proportional to its velocity just after impact, so momentum before and after can be compared directly.

Repeating runs from the other holes shows how a greater drop height raises the incident speed, and comparing kinetic energy before and after tells students whether a collision was elastic or inelastic. Where the balls leave in different directions, their momenta are resolved into components in the horizontal plane. A plumb line marks the floor point below the launch position, making the apparatus a natural companion to the projectile motion kit school labs already use.

What to Specify When Ordering

• The number of sets needed for your laboratory
• Confirmation of the incident and target balls supplied, and any spare balls
• Measuring accessories to order with it, such as a plumb line and a metre scale

OEM Manufacturer

Jain Scientific Equipments Private Limited, the company that trades as ScienceLab, is the OEM (original equipment manufacturer) of the Apparatus Collision 2 Dimension. The apparatus is manufactured at its licensed factory at Saha, Ambala, Haryana, India, and sold factory-direct, so schools, colleges and dealers deal with the maker itself for quotations, repeat orders and any replacement parts they need. Company background is on our company profile.

Related Physics Lab Equipment

Items used with this apparatus when measuring collisions:

• Apparatus Falling Bodies (Projectile) — studies the projectile paths the balls follow after impact
• Plumb Line Level — marks the floor point directly below the launch position
• Meter Scale 100 cm — measures the horizontal range of each ball
• Vernier Calliper — measures ball diameters when locating the centres of impact
• Apparatus Air Track Light Gate — one-dimensional collisions with carts and electronic timing

More mechanics apparatus is listed in the Physics Lab Equipment category.

Frequently Asked Questions

What does the Apparatus Collision 2 Dimension demonstrate?
The Apparatus Collision 2 Dimension demonstrates how momentum and kinetic energy change when one ball strikes another, letting students compare elastic and inelastic collisions. The collision takes place only in the horizontal plane, which keeps the calculations simple.

How is the drop height kept the same on every run?
The Apparatus Collision 2 Dimension has a pin and three holes in its curved track. Setting the pin in a hole fixes where the incident ball is released, so the drop height, and therefore the speed at impact, stays consistent between runs.

How is the target ball positioned on the Apparatus Collision 2 Dimension?
On the Apparatus Collision 2 Dimension, a support on the base holds the target ball at the proper height for a centre-to-centre collision with the ball rolling down the track. The base is permanently mounted at one end of the curved track.

Apparatus Conductivity Cam (Product Code: SLE/PHY/07) is a thermal-conductivity demonstrator used to compare how well different metals conduct heat in school and college physics classes. Metal rods are mounted vertically on the outside of the base of a cylindrical copper vessel, and the indices supplied with it let students mark results so they can be studied later. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Metal Conductivity Apparatus Used For?

The vessel is supported by its rim in a ring on a retort stand, so the rods hang below it. Hot water fills the copper vessel and heat travels down each rod at a rate set by the conductivity of its metal. A common way to make the difference visible is to coat the rods thinly with wax beforehand: the wax melts furthest along the better conductors, and students use the indices to mark how far the melting has reached on each rod.

Because the indices hold the readings, the class can compare the rods after the apparatus has cooled, rank the metals from better to poorer conductor, and relate the result to everyday choices such as copper-bottomed pans. Keep the vessel steady in its ring while filling it, keep hands clear of the hot copper, and let everything cool before the indices are handled.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which markets its products under the ScienceLab name, is the OEM (original equipment manufacturer) of this conductivity apparatus and one of the physics instruments manufacturers based in Ambala, Haryana. The apparatus is manufactured at the company’s own licensed factory at Saha, Ambala, and shipped factory-direct to schools, colleges, science dealers and importers. For replacement indices or a repeat order, ask us directly; our company profile has more about the company.

Apparatus Convection In Liquid (Product Code: SLE/PHY/08) is a rectangular loop of glass tubing used to show convection currents circulating in water in school and college physics and science classes. The 350 × 210 mm rectangle is made from 22 mm glass tubing, so a few potassium permanganate crystals trace the moving water clearly when one lower corner is gently heated. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Convection Tube Used For?

Fill the rectangle with water, clamp it upright in a retort stand and drop a few potassium permanganate crystals into the tube. When a small flame warms one lower corner, the heated water expands, becomes less dense and rises up that side, while cooler water sinks down the opposite side to replace it, and the purple colour shows the whole loop circulating. The demonstration links directly to sea breezes, hot-water systems and the way a pan of water heats from the bottom.

Use only a gentle flame on one corner, never the whole base, so that a single clear current forms. Warm the glass gradually to avoid thermal shock, use just a few crystals so the colour stays traceable, and let the water cool before emptying and rinsing the tube. It gives any heat energy science kit a vivid, reusable convection demonstration for middle and secondary classes.

Apparatus Coulomb's Law (Product Code: SLE/PHY/09) is an electrostatics apparatus used to verify Coulomb's law by directly measuring the force between two charged spheres in school and college physics labs. One sphere hangs from the top of a box and the other rests on its bottom; students read the hanging sphere's deflection on a ruler, with a mirror to remove parallax. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Coulomb's Law Apparatus Used For?

When the two spheres carry like charges and are brought together, the hanging sphere is pushed aside. Its sideways deflection, read on the ruler while lining the sphere up with its reflection in the mirror, lets students calculate the electrostatic force from the geometry of the suspension. Repeating the reading at different separations shows the force falling as the spheres move apart, which students then compare with the inverse-square relationship.

Electrostatic experiments work best in dry air, so run them away from open windows and humid corners, and discharge both spheres by touching them to earth between trials. Charge them from a source such as a friction rod or a suitable high-voltage supply, and keep hands and sleeves clear of the box while readings are taken. As educational physics lab equipment, it turns an abstract formula into a quantity students can measure for themselves.

OEM Manufacturer

Jain Scientific Equipments Private Limited sells under the ScienceLab brand and is the OEM (original equipment manufacturer) of the Apparatus Coulomb's Law. The apparatus is manufactured at the company’s licensed factory at Saha, Ambala, Haryana, India, and delivered fully assembled, so institutions and dealers buy it straight from the maker and can ask us directly about repeat orders or replacement parts. The company profile has more about the business.

• Van de Graaff Generator — a source of charge for the spheres
• EHT Power Supply — an adjustable high-voltage supply for charging
• Friction Rod, Brass/Ebonite — charges the spheres by friction and contact in simple classes
• Electroscope, Gold Leaf — confirms the presence of charge before readings are taken
• Electrostatic Investigation — a related electrostatics item in the same range

Frequently Asked Questions

What does the Apparatus Coulomb's Law measure?
The Apparatus Coulomb's Law measures the force between two charged spheres directly. One sphere hangs from the top of a box and deflects away from the other, and students read that deflection on a ruler to calculate the force and test Coulomb's law.

How does the mirror improve accuracy on the Apparatus Coulomb's Law?
The Apparatus Coulomb's Law includes a mirror that eliminates parallax. Students line up the hanging sphere with its reflection before reading the ruler, so the eye is square to the scale and every reading is taken from the same viewpoint.

Does the Apparatus Coulomb's Law need assembly?
No, the Apparatus Coulomb's Law is fully assembled and self-contained, with the spheres, box, ruler and mirror arranged ready for use. Teachers only need a means of charging the spheres before the class starts taking readings.

How are the spheres of the Apparatus Coulomb's Law charged?
The charging method is not specified in the description of the Apparatus Coulomb's Law. A friction rod or a suitable high-voltage source is commonly used in electrostatics work; tell us what your lab already has and we will advise on what fits.

Why can readings on the Apparatus Coulomb's Law vary from day to day?
Readings on the Apparatus Coulomb's Law can vary because charge leaks away faster in humid air. Work in a dry room, recharge the spheres before each set of readings, and take several measurements at each separation to average out the effect.

Who manufactures the Apparatus Coulomb's Law?
The Apparatus Coulomb's Law is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its licensed factory at Saha, Ambala, Haryana, India, and sold factory-direct to schools, colleges, dealers and importers.

Can the Apparatus Coulomb's Law be supplied for export?
Yes, the Apparatus Coulomb's Law can be quoted for schools, colleges, dealers and importers in India and international markets. Send the quantity and destination through our contact page, and the quotation will come directly from the manufacturer.

Apparatus Falling Bodies (Projectile) (Product Code: SLE/PHY/10) is a spring-release demonstration block used to show that the horizontal and vertical motions of a projectile are independent in school and college physics labs. One press of the trigger catch drops one steel ball straight down and projects a second sideways, and both strike the floor at the same instant. This compact projectile motion kit for school classrooms is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Falling Bodies Projectile Apparatus Used For?

Many students expect a ball fired sideways to stay in the air longer than one that is simply let go. This apparatus tests that idea directly: set the block at the edge of a level bench, place the two steel balls in position and release the trigger catch. The launching bar swings, one ball falls straight down while the other flies out horizontally, and the class hears a single sound as both land together.

The lesson is that gravity gives both balls the same downward acceleration whatever their sideways speed, so the horizontal motion does not change the time of fall. Run it over a hard floor so the landings are easy to hear, keep the landing zone clear, and return the balls to the recess in the block after use. It fits naturally into mechanics lab equipment for secondary and senior-secondary projectile lessons.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this falling bodies apparatus. It is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, and sold factory-direct rather than through a trading middleman. Schools, colleges, laboratory dealers and importers deal with the maker itself, so questions about spare steel balls or repeat orders reach the people who build the unit — just ask us. More about the company is on the ScienceLab company profile.

• Guinea & Feather Apparatus — shows how air resistance, not mass, changes how bodies fall.
• Apparatus Newton's Second Law — a clamp-mounted spring unit that also drops one ball while projecting another.
• Meter Stick, White — for measuring the drop height and the horizontal landing distance.

See the complete range of Physics Lab Equipment from ScienceLab.

Frequently Asked Questions

What does the Apparatus Falling Bodies (Projectile) demonstrate?
The Apparatus Falling Bodies (Projectile) demonstrates that horizontal and vertical motions are independent. When the trigger catch is released, one steel ball drops vertically while the other is projected horizontally, and both hit the floor at the same time because gravity accelerates each of them downward equally.

What comes with the falling bodies projectile apparatus?
The falling bodies projectile apparatus consists of a wooden block of about 190 x 58 x 30 mm carrying a pivoted L-section, spring-loaded metal launching bar with a trigger catch. It is supplied with 2 steel balls, which are kept in a storage recess in the block.

How should the projectile apparatus be set up in class?
Place the Apparatus Falling Bodies (Projectile) at the edge of a level bench above a hard floor, so the two landings can be heard clearly. Keep students out of the landing area, release the trigger catch, and then return both steel balls to the recess in the block.

Who manufactures the Apparatus Falling Bodies (Projectile)?
The Apparatus Falling Bodies (Projectile) is manufactured by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, as the OEM at its own factory in Saha, Ambala, Haryana, India. Buyers order it direct from the manufacturer instead of through a reseller.

What should a quotation request for SLE/PHY/10 include?
A quotation request for the Apparatus Falling Bodies (Projectile), code SLE/PHY/10, should state the quantity, the delivery city or country, and any other physics items you want on the same order. Send these details through the ScienceLab contact page for a quote from the manufacturer.

Apparatus Force of Conductor (Product Code: SLE/PHY/11) is a rolling-axle demonstration unit used to show Fleming's left-hand rule, the force on a current-carrying conductor in a magnetic field, in school physics labs. A brass axle with plastic discs rests on a pair of brass rails between the poles of a strong U-shaped magnet, and it rolls one way or the other depending on the direction of the current. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Force of Conductor Apparatus Used For?

This is the classic "motor effect" demonstration. Current enters one brass rail through a 4 mm socket, crosses the brass axle and leaves by the other rail, so the axle itself becomes the conductor sitting in the field of the U-shaped magnet. As soon as current flows, the axle is pushed along the rails; reverse the supply leads, or turn the magnet over, and it rolls back the other way. Students can predict each result with Fleming's left-hand rule before switching on.

Use a low-voltage DC source and switch the current on only briefly, as a short circuit through the rails and axle warms the leads quickly. The plastic discs keep the axle rolling true on the rails, so the effect is easy to see from the back of the room. As an electromagnetic kit for school physics, it links neatly to lessons on electric motors and on current-carrying coils.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer (OEM) of the Apparatus Force of Conductor. The unit is built at the company's licensed factory at Saha, Ambala, Haryana, India, and goes out factory-direct to schools, teacher-training colleges, dealers and importers. If you later need a replacement axle, rails or magnet, or want to repeat an earlier order, ask the manufacturer directly. Read more on the company profile page.

Related Physics Lab Equipment

To run the demonstration and extend it into a full electromagnetism lesson, labs usually add:

• Power Supply, Stepped — a bench supply for sending current through the rails.
• Stackable Leads — leads for joining the supply to the socket terminals.
• Knife Switch – Single Pole — lets the teacher apply current in short bursts.
• Force on a Conductor Apparatus — an alternative design for the same Fleming's rule experiment.
• Induced Current Apparatus — shows the reverse effect, where motion in a field produces current.

More items are listed under Physics Lab Equipment.

Frequently Asked Questions

What does the Apparatus Force of Conductor demonstrate?
The Apparatus Force of Conductor demonstrates that a conductor carrying current in a magnetic field is pushed by a force. The brass axle rolls along the brass rails in one direction, and reverses when the current direction is reversed, which students can check with Fleming's left-hand rule.

What parts make up the force of conductor apparatus?
The force of conductor apparatus comprises a strong U-shaped magnet, a pair of brass rails fitted with 4 mm socket terminals, and a brass axle with plastic discs that is free to roll along the rails. A DC supply and connecting leads are needed to run it.

What power source does the Apparatus Force of Conductor need?
The Apparatus Force of Conductor is run from a low-voltage DC source connected to the 4 mm sockets on the brass rails. Switch the current on only for short periods. For advice on a supply that suits your lab, send your existing equipment list through the ScienceLab contact page.

Who manufactures the Apparatus Force of Conductor?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, manufactures the Apparatus Force of Conductor as the OEM at its own factory in Saha, Ambala, Haryana, India. Schools and dealers buy it direct from the manufacturer and can ask the same team for replacement parts.

Which class levels use the force of conductor apparatus?
The Apparatus Force of Conductor suits secondary-school lessons on the motor effect and Fleming's left-hand rule, and it is also used for revision demonstrations in senior-secondary and junior college physics. Teachers use it before introducing the electric motor so students first see the basic force on a single conductor.

Apparatus Heat/Thermal Conductivity (Product Code: SLE/PHY/12) is a four-metal comparison ring used to show that different metals conduct heat at different rates in school science and physics labs. Four pointed strips of aluminium, brass, copper and iron meet at the centre of a wooden compound ring, and each carries a small water-holding indentation at its outer end, so the class can watch which drop dries first. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Thermal Conductivity Apparatus Used For?

The apparatus turns an abstract property into a race. Put an equal drop of water in the indentation at the end of each strip, then warm the centre of the ring where the four points meet, for example over a small spirit-lamp flame. Heat travels outward along each strip at a rate set by its metal, so the drops begin to steam and dry in a clear order. Copper, which conducts heat fastest of the four, usually finishes first and iron last, with aluminium and brass in between.

Because all four strips share one heat source, the comparison is fair without any extra measuring instruments, which makes it a simple heat energy science kit for middle and secondary classes. Let the ring cool before refilling the indentations, and keep the flame under the centre only so the wooden ring is not scorched. Older students can follow up with measured experiments on conduction in rods.

OEM Manufacturer

This thermal conductivity ring is an OEM product of Jain Scientific Equipments Private Limited, the company behind the ScienceLab name. It is produced at the company's licensed factory at Saha, Ambala, Haryana, India, and reaches schools, colleges, dealers and importers directly from the manufacturer, not through a trading house. For institutional vendor registration, the company's details are GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. Background on the company is on the ScienceLab profile page.

Frequently Asked Questions

What does the Apparatus Heat/Thermal Conductivity show?
The Apparatus Heat/Thermal Conductivity shows that metals conduct heat at different rates. When the centre of the ring is heated, the water held at the end of the aluminium, brass, copper and iron strips evaporates at different times, revealing which metal carries heat fastest.

Which metals are used in the thermal conductivity apparatus?
The thermal conductivity apparatus uses four pointed strips, each made of a different metal: aluminium, brass, copper and iron. They are fixed at 90 degrees to each other around a wood compound ring, with their points meeting at the centre, where heat is applied.

In what order does the water dry on the conductivity ring?
On the Apparatus Heat/Thermal Conductivity, the water at the end of the copper strip usually dries first because copper conducts heat fastest of the four metals, and iron is usually last. Room draughts and uneven drops can change the result, so repeat the test for a fair comparison.

Who manufactures the Apparatus Heat/Thermal Conductivity?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, is the OEM manufacturer of the Apparatus Heat/Thermal Conductivity. It is made at the company's own factory in Saha, Ambala, Haryana, India, and supplied direct to schools, colleges, dealers and importers.

What heat source is needed for the thermal conductivity ring?
The Apparatus Heat/Thermal Conductivity needs a small flame, such as a spirit lamp or a low Bunsen flame, placed under the centre where the four metal points meet. The heat source is not part of the apparatus, so order it separately if your lab does not already have one.

Can ScienceLab supply this apparatus for a whole school lab or export order?
Yes. ScienceLab supplies the Apparatus Heat/Thermal Conductivity singly or in quantity for school labs, dealers and importers in India and international markets. Send the required quantity and destination through the contact page to receive a quotation from the manufacturer.

Apparatus Inertia (Product Code: SLE/PHY/13) is a spring-flick demonstration set used to illustrate inertia, the tendency of a body at rest to stay at rest, in primary, middle and secondary school science classes. In this hands-on physics demonstration kit, a spring snaps a card out from under a glass ball, and the ball drops into the cup on the post instead of flying off with the card. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Inertia Apparatus Used For?

It is the classroom version of pulling a tablecloth from under the dishes. The card is laid over the cup on the post, the glass ball rests on the card on its 5 mm flat spot, and the spring is pulled back. When the spring is let go it strikes the card sharply and sends it flying, but the ball, which was at rest, tends to stay at rest. The brief friction from the card moves it only a little, so it drops straight down and settles into the cup instead of travelling with the card.

Ask students to predict the outcome before each release, then repeat with a coin in place of the ball to show the same effect on a different object. A quick, confident release gives the cleanest result; a slow push drags the ball along and is itself a useful comparison. As a force motion experiment kit, it opens discussion of Newton's first law, seat belts and why loose objects slide in a braking bus.

OEM Manufacturer

ScienceLab is the brand name of Jain Scientific Equipments Private Limited, which is the OEM for the Apparatus Inertia. The set is manufactured at the company's own licensed factory in Saha, Ambala, Haryana, India, and supplied straight from there to schools, science centres, dealers and importers. Because the maker handles every enquiry, spare glass balls or cards and repeat class sets can simply be requested from us. Company details are on the ScienceLab profile.

Related Physics Lab Equipment

Teachers covering Newton's laws and momentum often pair this set with:

• Newton's Pendulum (Newton's Cradle) — carries the lesson on to momentum and energy transfer in collisions.
• Dynamics Trolley, Plastic — for experiments on force, mass and acceleration.
• Apparatus Collision 2 Dimension — a follow-on apparatus for studying collisions.
• Apparatus Falling Bodies (Projectile) — another quick mechanics demonstration built around a spring release.

The full list is under Physics Lab Equipment.

Frequently Asked Questions

What does the Apparatus Inertia demonstrate?
The Apparatus Inertia demonstrates that a body at rest tends to stay at rest. When the spring flicks the card away, the glass ball does not travel with it; it drops into the cup on the post, showing inertia and introducing Newton's first law of motion.

What is included in the Apparatus Inertia set?
The Apparatus Inertia set contains a glass ball, a card, a plastic base, a post, the fitting hardware and instructions. The spring used to flick the card forms part of the apparatus, and the glass ball has a 5 mm flat spot so it can rest steadily on the card.

Why does the inertia apparatus ball have a flat spot?
The glass ball of the Apparatus Inertia has a 5 mm flat spot so it can sit on the card without rolling off before the spring is released. The flat spot keeps each trial starting from rest, which makes the inertia effect repeatable for the whole class.

Can the inertia apparatus be used with other objects?
Yes. Besides the glass ball supplied with the Apparatus Inertia, the same experiment can be tried with a coin placed on the card. Comparing the two helps students see that inertia is a property of all objects, not only of the ball.

Who manufactures the Apparatus Inertia?
The Apparatus Inertia is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own factory in Saha, Ambala, Haryana, India. The company supplies it directly to schools, dealers and importers, and handles requests for replacement parts itself.

Apparatus Newton's Ring (Product Code: SLE/PHY/14) is an optical interference unit used to display the ring pattern formed when light reflects between two surfaces, in physics and optics lab classes. A convex lens rests on a flat lens inside a metallic frame with three terminals, and the complete ring measures 4 inches in diameter and 1-1/2 inches thick. Schools and colleges use it as a sturdy Newton rings apparatus made in India by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala.

Specifications

What Is the Newton's Ring Apparatus Used For?

Where the curved face of the convex lens meets the flat lens, a very thin film of air is trapped, growing thicker away from the contact point. Light reflected from the two surfaces bounding this film interferes, and wherever the path difference matches, the reflections reinforce or cancel. The result is a set of concentric rings centred on the point of contact, a clear visual proof that light behaves as a wave.

Viewed under a monochromatic source such as a sodium lamp, the unit shows crisp alternating dark and light rings that advanced students can measure to find the radius of curvature of the lens or the wavelength of the light. Under ordinary white light the same pattern appears as rainbow-coloured rings, which is ideal for a quick class demonstration. Handle the lenses by the frame only and keep them free of dust, since any particle between the glass surfaces spoils the rings. It suits any optics lab equipment set for senior-secondary and undergraduate practicals.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Apparatus Newton's Ring. The unit is manufactured at the company's licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to colleges, schools, laboratory dealers and importers. Buying from the maker means one point of contact for quotations and for any later replacement parts or matching units — just ask us. See the company profile for background.

Related Physics Lab Equipment

A complete Newton's rings experiment normally needs a light source and a measuring instrument as well:

• Sodium Spectral Lamp — a monochromatic source for sharp dark and light rings.
• Spectral Lamp Power Supply with Lamp Holder — powers and holds the spectral lamp.
• Vernier Travelling Microscope — for measuring ring diameters in quantitative work.
• Newton's Ring Model — an alternative Newton's ring unit in a different frame design.

Frequently Asked Questions

What does the Apparatus Newton's Ring show?
The Apparatus Newton's Ring shows the interference pattern produced when light reflects between two surfaces: the curved face of a convex lens and the flat lens beneath it. The trapped air film produces concentric rings around the contact point, demonstrating the wave nature of light.

What size is the Newton's ring apparatus?
The Apparatus Newton's Ring measures 4 inches in diameter and 1-1/2 inches thick. Its convex lens and flat lens are held together in a metallic frame with three terminals, making it compact enough to place on an optical bench or under a microscope.

What light source is needed to see the rings?
The Apparatus Newton's Ring can be viewed with monochromatic light, which gives a series of dark and light rings, or with white light, which gives rainbow-coloured rings. For measurements, a monochromatic source such as a sodium lamp is the usual choice.

Who manufactures the Apparatus Newton's Ring?
The Apparatus Newton's Ring is manufactured by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab, as the OEM at its own factory in Saha, Ambala, Haryana, India. Colleges and dealers buy it direct from the manufacturer rather than through a trader.

How should the Newton's ring lenses be cared for?
Keep the Apparatus Newton's Ring in a dust-free box, hold it only by the metallic frame, and clean the outer glass faces with a soft lens tissue. Dust or fingerprints between or on the surfaces distort the rings and make diameter readings unreliable.

Can a calibration certificate be provided with SLE/PHY/14?
Whether any calibration or test document can accompany the Apparatus Newton's Ring, code SLE/PHY/14, should be discussed with ScienceLab before ordering. Mention this requirement in your enquiry through the contact page along with the quantity and delivery location.

Apparatus Microwave (Product Code: SLE/PHY/15) is a microwave optics kit used to demonstrate the wave properties of electromagnetic microwaves, namely reflection, polarization, diffraction and interference, in senior school and college physics labs. It pairs a microwave transmitter with a receiver, audio amplifier and loudspeaker, so students hear as well as measure changes in the signal, and it runs from a 12V DC supply. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a wave motion kit for school and college use.

Specifications

What Is the Microwave Apparatus Used For?

Microwaves have wavelengths of a few centimetres, so effects that need a microscope or a laser with visible light can be shown on an ordinary bench. With the transmitter aimed at the receiver, students tilt an aluminium reflector and follow the reflected beam, rotate the polarization grille to make the signal fade and return, send the beam past the narrow reflector to see it spread by diffraction, and set up two paths to produce interference maxima and minima. The loudspeaker makes every change audible to the whole class.

Each result can then be compared directly with the matching experiment in light, which is the main teaching value of the kit. Keep the reflectors flat and clean, work on a clear bench away from metal cupboards that cause stray reflections, and follow the instruction booklet for set-up and safe use. It is a useful piece of physics lab equipment for India's senior-secondary and undergraduate wave-optics topics.

Apparatus Newton's Second Law (Product Code: SLE/PHY/16) is a clamp-mounted spring launcher used to help students visualize and grasp Newton's Second Law of Motion in school physics labs. The sturdy unit projects one ball horizontally while another drops vertically, and both land at the same time; its spring can propel a ball 48 inches from the starting point. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for school physics lab equipment sets in India and abroad.

Specifications

What Is the Newton's Second Law Apparatus Used For?

Once released, each ball has only one force acting on it, its weight, which points straight down. By Newton's second law, the same force per unit mass gives both balls the same downward acceleration, so the one that is launched sideways and the one that simply drops reach the floor together. No horizontal force acts after launch, so the projected ball keeps a steady sideways speed as it falls. Students see and hear the second law at work.

Clamp the unit with its detachable rod to the edge of a bench or to a laboratory stand so it stays rigid when the spring fires. With the horizontal range of up to 48 inches marked on the floor and the launch height measured, older students can calculate the launch speed and fall time. Keep the landing area clear and let the class predict the result before each trial.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), the OEM behind the Apparatus Newton's Second Law.

Apparatus Young Modulus Searle's (Product Code: SLE/PHY/17) is a twin-frame extension apparatus used to determine the Young's modulus of a wire by Searle's method in college and senior-secondary physics labs. Two hinged cast metal frames, a spirit level on a pivoted cross-bar and a micrometer head reading to 0.01 mm let students measure very small extensions; brass and steel wires 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 Searle's Young Modulus Apparatus Used For?

Young's modulus tells us how stiff a material is, and Searle's method measures it on a long, thin wire. The two wires hang from the chucks of the ceiling bracket and pass into the self-centering chucks of the two frames. One frame carries the counterpoise weight to keep its wire taut as a reference, while load is added to the hook of the other. Because the frames are hinged to move only vertically, any stretch of the loaded wire tilts the spirit level on the cross-bar.

After each load change, the micrometer head is turned until the bubble is level again, and the change in reading gives the extension to 0.01 mm. Plotting load against extension, then using the wire's length and diameter, gives Young's modulus as stress divided by strain. The Searle's method Young's modulus experiment is a standard practical in India's senior-secondary (including CBSE class 11) and undergraduate physics courses. Add and remove load gently, and stay well within the elastic limit so the wire returns to its original length.

What to Specify When Ordering

• Number of complete apparatus sets required for the lab.
• Whether you need extra brass or steel wires beyond the set of two supplied.
• Loading weights and hanger, which are not listed in the kit contents.
• Mounting: the kit includes a ceiling bracket; mention it if a wall mounting suits your lab better.

Balance Demonstration Fulcrum/Lever (Product Code: SLE/PHY/18) is a meter-stick lever set used to teach the relationship between the length of a lever arm, the moment of a force and the amount of force, in school physics labs. With a meter stick, a stand, three knife-edge clamps and 50 gram and 100 gram hooked weights, students balance real loads and see the law of moments at work. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Lever and Fulcrum Balance Used For?

One knife-edge clamp on the meter stick rests on the stand as the fulcrum, and the other two clamps carry the 50 gram and 100 gram hooked weights. Students slide the weights along the stick until it balances, then read each distance from the fulcrum straight off the stick's scale. They soon find that the 50 gram weight must hang twice as far from the pivot as the 100 gram weight, because the moments on either side must be equal: force multiplied by distance on the left equals force multiplied by distance on the right.

Moving the fulcrum away from the centre brings the stick's own weight into play, which lets older students locate its centre of gravity or estimate its mass from the balance point. The set works well as a moment bar apparatus for school practicals and as a quick teacher demonstration of why a long spanner or crowbar makes work easier. Handle the knife edges carefully and keep them clean so the stick pivots freely.

OEM Manufacturer

ScienceLab is how Jain Scientific Equipments Private Limited trades, and the company is the OEM (original equipment manufacturer) of the Balance Demonstration Fulcrum/Lever. The set is manufactured at its licensed factory at Saha, Ambala, Haryana, India, then supplied factory-direct to schools, colleges, dealers and importers. Extra knife-edge clamps, replacement weights or repeat class sets are handled by the manufacturer itself, so just ask us. Read more on the company profile.

The complete range is in Physics Lab Equipment.

Frequently Asked Questions

What does the Balance Demonstration Fulcrum/Lever teach?
The Balance Demonstration Fulcrum/Lever teaches the relationship between the length of a lever arm, the moment of force and the amount of force. By adjusting weights on the meter stick until it balances, students observe the law of torque, also called the principle of moments.

What parts are in the fulcrum and lever balance set?
The Balance Demonstration Fulcrum/Lever consists of a meter stick, a stand, three knife-edge clamps, one 50 gram hooked weight and one 100 gram hooked weight. One clamp forms the fulcrum on the stand and the other two hold the weights on the stick.

How do students find the balance point with this lever set?
With the Balance Demonstration Fulcrum/Lever, students move the hooked weights along the meter stick until it rests level, then read each distance from the fulcrum. Multiplying each weight by its distance shows that the moments on both sides are equal at equilibrium.

Who manufactures the Balance Demonstration Fulcrum/Lever?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, manufactures the Balance Demonstration Fulcrum/Lever as the OEM at its own factory in Saha, Ambala, Haryana, India. It is sold direct from the manufacturer to schools, colleges, dealers and importers.

Balance Spring Tubular Plastic (Product Code: SLE/PHY/19) is a tubular spring balance used to measure forces, such as the pull of gravity on a mass, in school physics and science labs. It is 250 mm long overall including its ring and hook, the spring mechanism is clearly visible through the plastic tube, and it carries a zero adjustment plus colour-coded ranges scaled in both grams and newtons. 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?

A spring balance is often the first force-measuring instrument students handle. Hang the balance by its ring, set the pointer to zero with the zero adjustment, then attach the load to the hook and read the scale. Because the scale is marked in both grams and newtons, one reading lets the class connect mass and weight and see how a load in grams corresponds to a force in newtons. The visible spring shows how the extension grows with the load, a direct link to Hooke's law.

Beyond weighing, students use it to measure friction by dragging a block across the bench, the pull needed to raise a load with pulleys, or the effort on a lever. The colour coding makes it easy to hand the right range to each group and to collect them again after class. Hold it vertically when weighing, re-zero before each set of readings and never load it past the end of its scale. It is everyday physics lab equipment in India's schools and junior colleges.

What to Specify When Ordering

• The range or ranges you need; each range is colour-coded, so ask us which ranges are available.
• Quantity per range, for example one per student group.
• Whether you want a mixed set of ranges for one lab.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM for the Balance Spring Tubular Plastic.

Bar Compound Copper & Iron (Product Code: SLE/PHY/20) is a bimetallic compound bar used to demonstrate the principle of the thermostat in school physics and general science labs. An iron strip and a copper-based strip are riveted together from end to end and mounted in a wooden handle, and when the bar is heated the unequal expansion of the two metals makes it bend. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Compound Bar Used For?

As a piece of physics lab equipment for India's heat and expansion lessons, it takes only a flame to use. Hold the bar by its wooden handle and pass it slowly through the flame so both strips warm evenly. The copper-based strip expands more than the iron for the same rise in temperature, but the rivets stop the strips from sliding past each other, so the whole bar curls with the iron on the inside of the curve. As it cools, the bar straightens again, showing that the effect is reversible.

That bending movement is exactly what switches a thermostat: in an iron, a room heater or a fire alarm, a bimetal strip moves as it warms and opens or closes an electrical contact. Students can predict which way the bar will bend before heating, then check. Keep the heating gentle, rest the hot bar on a heat-proof mat afterwards, and never touch the metal until it has cooled.

What to Specify When Ordering

• Confirm the metal pair you need: the product name lists copper and iron, while the earlier catalogue text lists brass and iron.
• Number of compound bars, for example one per student group or one for teacher demonstration.
• Whether a heat source such as a Bunsen burner should be quoted with the bars.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of the Bar Compound Copper & Iron. The company manufactures it at its licensed factory in Saha, Ambala, Haryana, India, and sells factory-direct to schools, colleges, dealers and importers. Jain Scientific Equipments Private Limited is a registered MSME whose major activity is manufacturing (Udyam UDYAM-HR-01-0003714), and export consignments move under Importer-Exporter Code AAECJ8618A issued by the DGFT. See the company profile for more.

Related Physics Lab Equipment

For a full set of thermal expansion demonstrations, pair the compound bar with:

• Bimetallic Strip — another bimetal item for the same thermostat lesson.
• Ball & Ring Apparatus — shows expansion of a solid when heated in a single metal.
• Apparatus Bar & Gauge — demonstrates linear expansion of a heated bar.
• Bunsen Burner — a heat source for warming the bar evenly.

More apparatus is listed in Physics Lab Equipment.

Frequently Asked Questions

What does the Bar Compound Copper & Iron demonstrate?
The Bar Compound Copper & Iron demonstrates the principle of the thermostat. Its two riveted metal strips expand by different amounts when heated, so the bar bends, just as the bimetal strip inside a thermostat bends to open or close an electrical contact.

Which way does the compound bar bend when heated?
When the Bar Compound Copper & Iron is heated, it bends with the iron strip on the inside of the curve, because the copper-based strip expands more than iron. On cooling, the bar returns towards its original straight shape.

What metals is the compound bar made of?
The Bar Compound Copper & Iron joins an iron strip to a copper-based strip, riveted from end to end in a wooden handle. The product name lists copper, while our earlier catalogue text lists brass, so please confirm the metal pair with ScienceLab when you enquire.

Who manufactures the Bar Compound Copper & Iron?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, manufactures the Bar Compound Copper & Iron as the OEM at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to schools, colleges, dealers and importers.

How should the compound bar be heated safely?
Hold the Bar Compound Copper & Iron only by its wooden handle and warm it gently and evenly in a flame. Place the hot bar on a heat-proof mat after the demonstration and do not touch the metal strips until they have cooled completely.

Battery Clip, PP3 (Product Code: SLE/PHY/21) is a standard snap-on battery connector used to take power from a PP3 battery into simple circuits in school physics and electronics labs. It has 150 mm leads and fits both PP3 batteries and press-stud type battery holders, so one clip style serves both power options on the bench. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a basic part for any electricity experiment kit a school assembles.

Specifications

What Is the PP3 Battery Clip Used For?

A PP3 battery has two press-stud terminals of different sizes at one end, and the clip snaps onto them in only one orientation, so the battery cannot be connected the wrong way round at the clip. The 150 mm leads then carry the supply to the rest of the circuit, whether that is a bulb holder, a buzzer, a small motor or a breadboard. The same clip also snaps onto press-stud type battery holders, which lets a class switch between a PP3 battery and a holder of cells without rewiring.

Before wiring, note which lead goes to the positive terminal and keep that polarity throughout the circuit. Never let the two lead ends touch while a battery is attached, as that shorts the battery and heats the wires. Unclip the battery at the end of each lesson so it does not drain in storage, and bend the leads gently so the joints at the clip last longer.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies the Battery Clip, PP3 from Ambala, Haryana, India. The company sources it as a standard component and ships it with other electricity and circuit items, so a school or dealer can place a single order for the whole circuit list. Ask us about quantities for class kits or for dealer stock. Company information is on the ScienceLab profile page.

Battery Snap with Crocodile Clip (Product Code: SLE/PHY/22) is a battery connector with crocodile clips attached, used to link a battery quickly to circuit components in school science and physics lessons. Because the clips grip terminals, wires and component legs directly, students can build and change circuits on the desk without screwdrivers or soldering. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, and is a handy part of any hands-on science kit for primary school and middle-school classes.

Key Details

What Is the Battery Snap with Crocodile Clip Used For?

Young students often struggle with small terminal screws, and loose connections are the most common reason a first circuit fails. With this connector the battery snaps on at one end and the crocodile clips at the other bite straight onto a bulb holder terminal, a switch, a buzzer lead or a bare wire. A circuit can be built, tested and rearranged in seconds, which keeps attention on the science rather than the wiring.

Teachers use it for series and parallel circuit activities, for testing which materials conduct electricity, and for quick demonstrations at the front of the class.

Bernoulli Tube Apparatus (Product Code: SLE/PHY/23) is a glass flow-tube set used to explain Bernoulli's theorem by showing how the pressure and speed of a flowing liquid change with the bore of a tube, in physics labs. It pairs a Bernoulli tube with a central narrowed portion and a constant-bore gradient tube, each 500 x 13 mm with three side tubes for glass manometers. This physics demonstration kit is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Bernoulli Tube Used For?

Water from a steady supply is run through one flow tube at a time, with a length of glass tubing standing upright in each side tube as a manometer and a swan-necked outlet at the far end. In the constant-bore gradient tube, the water levels in the three manometers fall evenly along the tube, showing the pressure drop along a uniform pipe. In the Bernoulli tube, the middle manometer, which taps the narrowed portion, stands noticeably lower than its neighbours.

That dip is Bernoulli's theorem in action: to pass the same volume each second through the constriction, the water must speed up, and its pressure falls. Comparing the two tubes side by side separates this effect from the ordinary friction loss. Keep the flow steady, clamp the manometer tubes upright, and handle the glass with care when fitting the rubber connectors. It is a clear, low-cost piece of physics lab equipment in India's senior-secondary and college fluid-flow practicals.

What to Specify When Ordering

• Number of complete sets; each set includes both flow tubes, 6 glass tubing lengths, 2 swan-necked outlets and 8 rubber connectors.
• Any spare glass tubing lengths or rubber connectors you want quoted.
• Stands or clamps for holding the manometer tubes upright, if your lab needs them.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, is the OEM of the Bernoulli Tube Apparatus. The set is manufactured at the company's licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers.

Frequently Asked Questions

What does the Bernoulli Tube Apparatus demonstrate?
The Bernoulli Tube Apparatus demonstrates Bernoulli's theorem: where a flowing incompressible liquid passes through a narrower section, its speed increases and its pressure falls. The manometer tapping at the narrowed portion of the Bernoulli tube shows this as a lower liquid level.

What is included in the Bernoulli Tube Apparatus?
The Bernoulli Tube Apparatus includes a Bernoulli tube with a central narrowed portion, a constant-bore gradient tube, 6 lengths of glass tubing, 2 swan-necked outlet tubes and 8 small pieces of rubber connecting tubing for joining the glass parts.

What size are the Bernoulli apparatus flow tubes?
Each flow tube of the Bernoulli Tube Apparatus measures 500 x 13 mm (length x outer diameter). Each has three sealed-in side tubes, 25 mm long and spaced about 150 mm apart, where glass tubing lengths are attached as manometers.

Why does the set include a constant-bore gradient tube?
The constant-bore gradient tube in the Bernoulli Tube Apparatus shows the steady pressure fall along a uniform tube. Comparing it with the Bernoulli tube lets students separate the pressure drop caused by the constriction from the ordinary loss along the length of the tube.

Bourdon Gauge (Product Code: SLE/PHY/24) is a dial pressure gauge used to measure and demonstrate positive gas and liquid pressures in general and laboratory work, including school and college physics classes. A substantial black needle reads against a 100 mm diameter white face scaled in kg/cm² and psi, and a clear Perspex back lets students watch the Bourdon mechanism move. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a physics instruments supplier in India for schools, colleges and dealers.

Specifications

What Is the Bourdon Gauge Used For?

Inside the gauge is a Bourdon tube, a curved, flattened metal tube that tends to straighten as the pressure inside it rises; a linkage turns that small movement into the sweep of the needle. With the Perspex back, students can see this happen while a teacher pumps air into the gauge through rubber tubing pushed onto the rifled inlet. It is used for gas-law work such as pressure against volume, for checking the pressure in a sealed container, and as a readable demonstration dial at the front of the class.

The dual scale lets students compare engineering units, and multiplying the kg/cm² reading by 10⁵ converts it to pascals with enough accuracy for class calculations. Use rubber tubing of 8 mm internal diameter so the connection seals well. The gauge is for positive pressures only: never connect it to a vacuum pump or any other source of negative pressure, as that could damage the apparatus.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies the Bourdon Gauge from Ambala, Haryana, India. The company sources this gauge and looks after quotations, packing and dispatch for schools, colleges, laboratory dealers and importers in India and international markets. For vendor registration, the supplying company's details are GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. The ScienceLab profile page gives more background.

Frequently Asked Questions

What is the Bourdon Gauge used for?
The Bourdon Gauge measures positive pressures, those above atmospheric, in general and laboratory use. In physics classes it demonstrates gas pressure and gas-law experiments, and its clear Perspex back lets students see how the Bourdon mechanism moves the needle.

What units does the Bourdon Gauge read?
The Bourdon Gauge has a 100 mm diameter white face with scales in kg/cm² (black) and psi (red). To express a reading in pascals, multiply the kg/cm² value by 10⁵, which is accurate enough for school and college calculations.

What tubing fits the Bourdon Gauge inlet?
The Bourdon Gauge has a rifled metal input tube designed to fit rubber tubing of 8 mm internal diameter. Push the tubing well onto the rifled inlet so the joint holds under pressure, and check it for leaks before taking readings.

Can the Bourdon Gauge be used with a vacuum pump?
No. The Bourdon Gauge is for positive pressures only, that is, pressures in excess of atmospheric. Connecting it to a vacuum pump or any other source of negative pressure could damage the apparatus, so use a gauge meant for vacuum work instead.

Who supplies the Bourdon Gauge?
The Bourdon Gauge is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company handles quotations and dispatch for schools, colleges, dealers and importers in India and international markets.

Boyle's Law – Simple Type (Product Code: SLE/PHY/25) is a sealed-syringe apparatus used to demonstrate Boyle's Law, the inverse link between the pressure and volume of a trapped gas, in school and college physics laboratories. Students load its wooden platforms with different masses and read the shrinking air volume straight from the syringe scale. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as simple, economical physics lab equipment for India and abroad.

Key Details

What Is the Boyle's Law Apparatus Used For?

The apparatus turns an abstract gas law into something students can see. With the syringe sealed, a known load is placed on the platform, the plunger settles, and the volume is noted from the scale. Adding further masses step by step shows the trapped air occupying less space each time the pressure on it rises, and a graph of volume against the inverse of the load brings out the relationship.

For cleaner results, add each mass gently and centrally, give the air a moment to return to room temperature between readings, and read the scale at eye level. Because it needs no pumps, gauges or oil, this simple type is a practical choice of physics practical equipment for CBSE and state-board classrooms where set-up time is short.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer of this Boyle's Law apparatus. It is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, and reaches schools, colleges, dealers and importers factory-direct rather than through a trading intermediary.

Because the maker handles your enquiry itself, questions about replacement syringes, platform parts or repeat orders for additional lab benches come straight to the people who build the unit, so just ask us. Read more about the company on our company profile.

Bucket & Cylinder, (Large) (Product Code: SLE/PHY/26) is a brass bucket-and-cylinder unit used to demonstrate Archimedes' principle in school and college physics laboratories. Its larger 60 mm size, 160 mm overall, gives the whole class a clear view when the teacher runs the experiment at the front bench. The unit is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, and is part of its physics lab equipment range.

Specifications

What Is the Large Bucket and Cylinder Used For?

The bucket and cylinder is the classic way to show that the upward thrust on an immersed body equals the weight of liquid it pushes aside. The bucket hangs from a spring balance by its top loop and the cylinder hangs from the bucket's bottom hook. When the cylinder is lowered into water the balance reading falls; filling the empty bucket with water brings the reading back, because in the classic demonstration the cylinder matches the inside of the bucket.

The large version suits teachers who want a bigger, easier-to-follow set-up during a lecture demonstration, while still being simple enough for a student to repeat the experiment afterwards. Use a vessel deep enough to cover the cylinder completely, and dry the brass after use. It is a staple item of mechanics lab equipment in India for classes studying buoyancy, floating and sinking.

What to Specify When Ordering

• Size: this large unit (60 mm, overall 160 mm) or the smaller Bucket & Cylinder, Small.
• Use: one set for teacher demonstration or several sets for individual student work.
• Any spring balance or water vessel you also want quoted with the sets.

OEM Manufacturer

Bucket & Cylinder, Small (Product Code: SLE/PHY/27) is a compact brass apparatus used to verify Archimedes' principle at student benches in school and college physics labs. At 50 mm, 115 mm overall, it is sized for pairs or small groups who weigh, immerse and refill it themselves during a practical period. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for school physics lab equipment in India and overseas.

Specifications

What Is the Small Bucket and Cylinder Used For?

Students use it to measure buoyant force for themselves. They record the balance reading with the cylinder hanging in air below the bucket, then again with the cylinder fully under water, and the difference gives the upthrust. Pouring water into the bucket until the first reading returns shows that the upthrust equals the weight of the water displaced, which is the heart of Archimedes' principle.

Because it is small, several sets fit on one bench and a narrow beaker or measuring cylinder is enough to submerge the cylinder. Encourage groups to lower the cylinder slowly so it does not touch the vessel walls, and to note each reading only after the balance stops moving. It makes an efficient addition to physics lab instruments in India where every pair of students needs its own set.

What to Specify When Ordering

• Number of sets, usually one per student pair or group.
• Whether you also want the larger Bucket & Cylinder, (Large) for the teacher's demonstration.
• Any balances or vessels to be included in the same quotation.

Caliper Vernier (Metal) (Product Code: SLE/PHY/28) is a nickel-plated steel vernier caliper used to measure external dimensions, internal dimensions and depth in school and college physics laboratories. Its metric scale reads from 0 to 120 mm in 1-mm divisions alongside a standard scale, and a roller adjustment moves the sliding head. It is supplied in a plastic case by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for institutions buying a Vernier caliper for school labs in India and abroad.

Specifications

What Is the Vernier Caliper Used For?

A vernier caliper is the standard tool for measuring small lengths more finely than a ruler allows. Students use the outside jaws for the diameter of a pendulum bob, rod or wire coil, the inside jaws for the bore of a tube or beaker, and the depth shaft for the depth of a calorimeter or a hole. Dimensions taken this way feed directly into volume and density calculations for metal blocks and cylinders.

Before each session, close the jaws gently and check whether the zero marks line up, so any zero error can be subtracted from later readings. Read the main scale first, then find the vernier mark that lines up most closely with a main-scale line. Wipe the steel clean after use and return it to its plastic case, a habit that suits any set of physics lab instruments in India that passes through many hands.

Calorimeter Set, Aluminium (Product Code: SLE/PHY/29) is a Joule's calorimeter set used to heat a liquid electrically and find specific heat capacity in school and college physics laboratories. An aluminium inner vessel sits inside a plastic outer vessel with custom-made foam insulation, heated by a 12 W precision heater, with a stirrer, stopper and spare cap included. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for calorimeter lab work across India and abroad.

Specifications

What Is the Aluminium Calorimeter Set Used For?

The set is built for the electrical method of measuring specific heat capacity. A weighed quantity of water or another liquid goes into the aluminium vessel, the heater is switched on, and students log the voltage, current, heating time and temperature rise. Equating the electrical energy supplied with the heat taken up by the liquid and the vessel gives the specific heat capacity, and the foam lagging keeps heat loss to the room low.

When a practical needs no heating, such as a method-of-mixtures experiment, the spare cap replaces the heater cap so the same vessels can be reused. Stir steadily while heating, start the clock at the moment the current is switched on, and keep reading the temperature for a short while after switching off to catch the peak. A thermometer is not included, so plan for one per set.

What to Specify When Ordering

• Number of calorimeter sets for your student groups.
• A thermometer for each set, since none is included.

Teachers order it to replace a lost or damaged holder, or to add extra lamps so students can compare brightness in series and parallel. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its electricity experiment kit range.

Key Details

What Is the Circuits Kit Bulb Holder Used For?

A bulb holder turns an invisible current into something pupils can see. Placed in a loop with a cell and a switch, the lamp lights only when the circuit is complete, which makes it the natural first component in lessons on open and closed circuits. Adding a second holder in series and then in parallel lets students compare brightness and discover how current and voltage are shared.

The lamp holder also works as a simple conductor tester: leave a gap in the circuit, bridge it with different materials, and the bulb shows which ones conduct. Because it sits on its own sturdy panel, it can be moved around the bench and packed away easily. Check that bulbs are screwed in firmly before switching on, and allow a lamp to cool before changing it.

What to Specify When Ordering

• The number of spare bulb holders needed for your kits.
• Whether bulbs are also required, and the lamp type your kits use.
• Any other Circuits Kit spares, such as switches or cell holders, to combine in one order.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM that makes this bulb holder at its own licensed factory at Saha, Ambala, Haryana, India. Because the spare comes from the same manufacturer as the rest of its circuits range, schools and dealers can ask us to match it to the kits they already hold.

Capillary Tube Apparatus (Product Code: SLE/PHY/32) is a demonstration apparatus used to show how the bore of a capillary tube affects the height to which water rises in it, in school and college physics laboratories. A metal frame holds six capillary tubes of different bores upright in a water trough, so the different column heights are visible at a glance. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for capillary tube experiments in India and abroad.

Specifications

What Is the Capillary Tube Apparatus Used For?

The apparatus demonstrates capillarity, one of the most visible effects of surface tension. Once water is poured into the trough, it climbs each tube to a different height: the narrower the bore, the higher the column. Seeing all six columns side by side lets students link the rise directly to tube diameter and discuss why capillary pressure increases as the bore gets smaller.

For the clearest display, use clean tubes, since grease inside a tube reduces the rise, and add a drop of coloured ink to the water so the columns stand out from the back of the room. Rinse and dry the tubes after use. The unit makes a useful companion to surface tension apparatus in India when a lesson needs a quick qualitative demonstration before quantitative work.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM that manufactures this capillary tube apparatus at its own licensed factory at Saha, Ambala, Haryana, India.

Conductive Putty (Product Code: SLE/PHY/38) is a mouldable conducting material used to teach resistivity and how the length and cross-sectional area of a conductor affect its resistance, in school and college physics labs. It comes as roughly 100 g of putty formed into a 60 mm long, 20 mm diameter cylinder of approximately 20 Ω that can be re-moulded to new shapes. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a hands-on addition to an Ohm's law experiment kit.

Specifications

What Is Conductive Putty Used For?

Conductive putty turns the resistivity equation into something students can shape with their hands. Starting from the supplied cylinder, they measure its resistance, then roll it longer and thinner and measure again, or keep the length fixed and change the diameter. Plotting resistance against length, and against the inverse of cross-sectional area, shows the two relationships clearly and lets them estimate the material's resistivity.

For consistent readings, press the connecting probes or plates into the ends of the putty to the same depth each time, measure length and diameter carefully after every re-moulding, and keep the current small so the putty does not warm up. Work on a clean surface so dust and fibres are not folded into the material, and store it covered between lessons.

Supplier

Conductive Putty is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab, from Ambala, Haryana, India. The company sources it for schools, colleges, dealers and importers and can include it in the same quotation as meters, leads and other resistance apparatus.

For details of pack quantities or combined orders, ask us, and see our company profile for more about ScienceLab.

• Conductive Paper — another conducting material for field and resistance work.

More items are in the Physics Lab Equipment category.

Frequently Asked Questions

How much Conductive Putty is supplied?
Conductive Putty is supplied as approximately 100 g, in the form of a cylinder 60 mm long and 20 mm in diameter. That starting shape has a resistance of approximately 20 ohms before students re-mould it.

What does Conductive Putty teach?
Conductive Putty is a teaching aid for resistivity and for the relationship between a conductor's length, its cross-sectional area and its resistance, because students can change both dimensions simply by re-moulding the putty and measuring again.

How is Conductive Putty connected into a circuit?
Conductive Putty can readily be connected into an electrical circuit by pressing leads, probes or contact plates into its ends. Keep the contact depth the same for each reading so that changes in resistance come from the shape, not the connections.

Component Holder (Product Code: SLE/PHY/40) is a pack of mounted clips used to hold components steady during physics investigations in school and college laboratories. Each pack contains 8 mounted clips, so one bench group can keep several parts of a set-up in position at once — a simple but useful item of physics lab equipment for schools in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Component Holder Used For?

Students use the Component Holder to grip a small part so it stays exactly where it is needed while the rest of the experiment is connected, observed or measured. In bench circuit work, for example, a held component no longer slides about when leads are clipped on, so meter readings stay steady and the layout on the bench matches the circuit diagram.

Because the clips are mounted rather than loose, they stand on the bench and can be arranged in a line or grid for series and parallel investigations, which makes them a handy addition to any electricity experiment kit at school level. A practical tip: give each group one pack of 8 and return the holders to a labelled tray after the lesson so the clips are not bent by heavier apparatus in storage.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of the Component Holder. The holders are made at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, institutions, dealers and importers instead of passing through a trader.

The company is incorporated under CIN U29309HR2020PTC087597, and its production site at 449, HSIIDC Industrial Area, Saha, Ambala operates under Factory Licence AMB-ONLINE-CHD-J-414. For repeat packs or replacement holders, ask us directly — you deal with the manufacturer itself. Read more on our company profile.

Protactinium Generator (Product Code: SLE/PHY/41) is a sealed, leak-proof container of material from the uranium-238 decay series used to observe radioactive decay and measure a half-life in school and college physics laboratories. Teachers choose it because the protactinium-234 it yields has a half-life of about 70 seconds, so a complete decay curve can be recorded within one practical — a staple of nuclear physics lab equipment. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Protactinium Generator Used For?

The Protactinium Generator is used for the classic half-life practical, in which the count rate from protactinium-234 is recorded at regular intervals and plotted against time. With a half-life of about 70 seconds, the count rate falls clearly within a few minutes, so students can read the half-life straight from their decay graph or from a log plot of count rate.

In a typical radiation experiment, a Geiger–Müller tube connected to a counter is placed close to the container, a background count is taken first, and counts are then recorded over short fixed intervals with the background subtracted. Keep the container closed at all times, handle it for the shortest time needed, and return it to a labelled, locked radioactive-materials store after the lesson.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies the Protactinium Generator to schools, colleges and institutions from Ambala, Haryana, India. The company sources this item for buyers and can combine it with detectors and counters from its physics range in one quotation. More about the company is on our profile page.

Related Physics Lab Equipment

A half-life practical with the Protactinium Generator needs a detector and a counter; these items complete the set-up:

• Scaler Timer — counts pulses manually or over timed intervals for the decay curve.
• Geiger Counter — hand-held survey meter for checking background and the source store.
• Apparatus for studying the value of the half-decay period during radioactive decay — an alternative half-life experiment.

See more in our Physics Lab Equipment range.

Frequently Asked Questions

What half-life is measured with the Protactinium Generator?
The Protactinium Generator is used to measure the half-life of protactinium-234, which is about 70 seconds. This short half-life lets students record the fall in count rate and determine the half-life within a single practical session.

How is the Protactinium Generator packed?
The Protactinium Generator comes in a sealed container with a leak-proof closure. The container should stay closed during use and storage, and it should be kept in a labelled, secure radioactive-materials store whenever it is not in use.

What else do I need to use the Protactinium Generator?
To take readings with the Protactinium Generator you need a Geiger–Müller tube in a holder, connected to a counter such as a scaler timer, plus timed counting or a clock. These items are sold separately and can be added to the same quotation.

Is an authorisation needed to buy the Protactinium Generator?

Geiger Muller Tube Holder (Product Code: SLE/PHY/42) is an aluminium box housing a G.M. tube socket, used to mount a Geiger–Müller tube and connect it to a counter for radioactivity measurements in physics laboratories. Designed for use with the Scaler Timer, it connects through a 1 m co-axial lead ending in a standard P.E.T. connector and has a stabilising resistor already wired inside. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the GM Tube Holder Used For?

The Geiger Muller Tube Holder turns a bare GM tube into a bench-ready detector. The tube plugs into the socket inside the aluminium box, and the co-axial lead links it to the counter, so students can place the detector at a measured distance from a source and record counts. Common practicals include background counts, count rate against distance, absorption by paper or metal sheets, and half-life measurement.

Because the 2.2 megohm stabilising resistor sits inside the box in series with the anode, there is no loose resistor to wire on the bench, which keeps a Geiger Muller tube set-up in an Indian school or college lab tidy and repeatable. Before counting, set the tube voltage on the counter to suit your GM tube, and keep the delicate tube window away from fingers and sharp objects.

What to Specify When Ordering

• Number of detector stations, i.e. how many Geiger Muller Tube Holders you need.
• Whether you also need the Scaler Timer the holder is designed to work with.
• Whether you need a GM tube, as a tube is not listed as part of the holder.

Teltron Electron Deflection Tube D (Product Code: SLE/PHY/44) is a highly evacuated electron tube used to show how electric and magnetic fields deflect an electron beam and to determine the specific charge e/m in physics laboratories. Its fluorescent screen, approx. 90 x 60 mm, is inclined to the beam axis so the whole beam path is visible, and a built-in plate capacitor provides the electric deflection. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Electron Deflection Tube Used For?

With the Teltron Electron Deflection Tube D, students watch the electron beam trace a visible path across the inclined screen, then bend it with the electric field between the capacitor plates and with the magnetic field of the Helmholtz coil pair D. Adjusting the electric field until it exactly cancels the magnetic deflection straightens the beam again, and from the two field values the electron velocity and e/m can be calculated. This field-cancellation method makes it a core specific charge electron experiment for undergraduate physics.

Plan the power arrangement with the tube: it needs a 6.3 V AC filament supply and a high-voltage source for the anode and capacitor, each rated up to 5000 V. Mount the tube securely, use shrouded leads for every high-voltage connection, and let the filament warm up before raising the anode voltage.

What to Specify When Ordering

• Whether you need the Helmholtz coil pair D for the magnetic deflection.
• Whether you need a tube holder and a high-voltage power supply, or already own them.
• Number of tubes, for example one for demonstration or several for student groups.

Teltron Tube Holder S (Product Code: SLE/PHY/45) is a stand used to mount Teltron Student (‘S’) Series electron tubes and their accessories for electron-beam experiments in physics laboratories. It carries the Helmholtz Coils S in slots with metric rulings that allow spacing up to 150 mm, and an easily replaceable fuse in the holder protects the tubes from excessive voltage. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Teltron Tube Holder Used For?

The Teltron Tube Holder S is the base on which every S-series experiment is built: the tube sits in the holder and the Helmholtz coils slot in on either side. The metric rulings on the coil slots let students set and record the spacing — at the Helmholtz geometry for a uniform field, or at other distances up to 150 mm to see how the field shape changes the beam.

Because the fuse sits in the holder itself, an accidental over-voltage blows a replaceable fuse rather than damaging a valuable tube, so keep spare fuses of the correct rating with the kit. A stable, well-organised stand like this is the foundation of a physics demonstration kit for teaching electron beams to senior students in India.

Teltron Electron Diffraction Tube D (Product Code: SLE/PHY/46) is a highly evacuated electron tube used to demonstrate the wave nature of electrons by diffraction through a polycrystalline graphite lattice in physics laboratories. The resulting rings appear on a fluorescent screen, and from their radii students determine the electron wavelength as a function of anode voltage, confirming de Broglie's hypothesis. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Electron Diffraction Tube Used For?

The Teltron Electron Diffraction Tube D gives one of the most direct demonstrations of wave–particle duality. Electrons accelerated by the anode pass through polycrystalline graphite and interfere, forming concentric Debye–Scherrer rings on the screen; as the anode voltage rises, the electron wavelength shortens and the rings visibly shrink.

Students record the ring radii at a series of anode voltages, then use the graphite lattice plane spacings of 0.213 nm and 0.123 nm to calculate the wavelength and compare it with the de Broglie prediction. As physics lab equipment for undergraduate modern physics courses in India, the rings are easiest to read in a darkened room with a supply able to reach 5 kV.

Supplier

ScienceLab (Jain Scientific Equipments Private Limited) supplies the Teltron Electron Diffraction Tube D from Ambala, Haryana, India. Teltron is a third-party brand; the company sources the tube and can quote it together with a D-series holder and a suitable high-voltage supply. Learn more on our company profile.

See the full Physics Lab Equipment category.

Frequently Asked Questions

What does the Teltron Electron Diffraction Tube D demonstrate?
The Teltron Electron Diffraction Tube D demonstrates the wave nature of electrons. Electrons passing through polycrystalline graphite produce Debye–Scherrer diffraction rings on a fluorescent screen, which lets students confirm de Broglie's hypothesis experimentally.

Which values are needed to calculate the electron wavelength?
With the Teltron Electron Diffraction Tube D you measure the ring radii and use the graphite lattice constants d10 = 0.213 nm and d11 = 0.123 nm. Repeating the measurement at several anode voltages shows how the wavelength depends on voltage.

What power supply does the Teltron Electron Diffraction Tube D need?
The Teltron Electron Diffraction Tube D needs a filament supply of up to 6.3 V AC and an anode supply of up to 5 kV; the anode current is approx. 0.1 mA at 4 kV. Ask us to include a suitable supply in your quotation.

Planck's Constant Apparatus (Product Code: SLE/PHY/47) is a ready-built circuit used to measure the photoelectric effect and determine Planck's constant in physics laboratories. Inside are a caesium antimony photocathode, a DC supply with a 10-turn potentiometer for the retarding voltage and a 0–19.99 V LED display, while six narrow-band filters vary the light frequency. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Planck's Constant Apparatus Used For?

Light of a known frequency, selected with one of the six filters, falls on the caesium antimony cathode and releases photoelectrons. Students raise the retarding voltage with the 10-turn potentiometer until the picoammeter reading falls to zero and note this stopping potential on the digital display. Repeating with each filter gives a set of stopping potentials that, plotted against frequency, form a straight line whose gradient is h/e.

Because the circuit is ready-built and battery-powered, set-up time is short, which makes it a practical photoelectric effect kit for senior secondary and undergraduate courses in India. The photocurrent is tiny, so the apparatus is ideally used with a picoammeter, connected through the supplied 4 mm to UHF lead.

What to Specify When Ordering

• Whether you need a picoammeter, which the apparatus is designed to work with but which is not listed as included.
• Confirmation of the six filter wavelengths on your quotation.
• Spare 9 V PP3 batteries.
• Number of units needed for your practical groups.

Teltron Helmholtz Pair of Coils S (Product Code: SLE/PHY/48) is a pair of coils used to generate a uniform magnetic field perpendicular to the axis of a Teltron S-series electron tube in physics laboratories. Each coil has 320 turns on a 138 mm diameter and carries 1.0 A continuously, giving a maximum field of approx. 9 mT for bending electron beams in e/m experiments. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Are Helmholtz Coils Used For?

Mounted on the Teltron Tube Holder S, the two coils sit either side of the tube so that a current through them bends the electron beam into an arc or circle. From the coil current, number of turns and diameter, students calculate the field strength and combine it with the accelerating voltage and beam radius to find the specific charge of the electron — the heart of any EM ratio apparatus set-up in Indian physics laboratories.

The holder also lets the coils be set at variable distances, or arranged to give a vertical or coaxial field relative to the tube axis, so the same pair serves experiments that need a different field direction. Keep the current at or below 1.0 A for long runs and use the 1.5 A rating only briefly; an ammeter in series makes it easy to stay within these limits.

What to Specify When Ordering

• Whether you need the Teltron Tube Holder S on which the coils are configured.
• A DC supply and ammeter for the coil current, suited to 1.0 A continuous operation.
• Which S-series tubes you will use with the coils.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies the Teltron Helmholtz Pair of Coils S from Ambala, Haryana, India, as part of its electron-beam experiment range. Teltron is a third-party brand; the company sources the coils and can quote them with the holder, tubes and meters that complete the set-up. Visit our profile page to learn more.

Plancks Constant Determination Box (Product Code: SLE/PHY/50) is an LED-based apparatus used to find an approximate value of Planck's constant from the elbow voltage in LED characteristic curves in physics laboratories. Seven LEDs, from deep blue at 470 nm to near infrared at 940 nm, are mounted on the box with sockets for voltage and current measurements, making it a compact Planck constant experiment kit. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Planck's Constant Box Used For?

Students connect each LED in turn, raise the voltage slowly and note the value at which it just begins to emit light — the elbow of its current–voltage curve. That voltage multiplied by the electron charge gives the energy of the emitted photons; plotting energy against light frequency, worked out from each LED's wavelength, gives a straight line whose gradient approximates Planck's constant.

With seven LEDs spread from 470 nm to 940 nm, the graph has enough points for a clear straight-line fit, and the exercise doubles as an LED characteristics experiment kit for electronics topics. For the near-infrared LED the light cannot be seen, so read its turn-on point from the current meter instead of by eye.

What to Specify When Ordering

• Power: whether you will use an external 9 V source or a 9 V battery.
• Connecting leads and meters for the voltage and current sockets.
• Number of boxes, for example one per bench group or one for demonstration.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies the Plancks Constant Determination Box from Ambala, Haryana, India, to schools, colleges and dealers.

Vendor details for purchase files: Jain Scientific Equipments Private Limited, CIN U29309HR2020PTC087597, GSTIN 06AAECJ8618A1ZT. More about the company is on our profile page.

Related Physics Lab Equipment

These items supply the power, connections and measurements the Plancks Constant Determination Box needs:

• Standard Digital Multimeter — measures the LED voltage and current.
• Digital Voltmeter — a dedicated bench voltmeter for the turn-on voltage.
• Crocodile Clips & Leads — connecting leads for the box and meters.
• Battery Clip, PP3 — connects a 9 V PP3 battery as the power source.
• Planck's Constant Apparatus — photoelectric method for a second, independent value.

Explore more Physics Lab Equipment.

Frequently Asked Questions

How does the Plancks Constant Determination Box find Planck's constant?

In the lab, the Teltron Electron Diffraction Tube S turns an abstract idea — electrons behaving as waves — into bright rings that students can measure. The inner and outer rings correspond to the two graphite lattice plane spacings, d10 = 0.213 nm and d11 = 0.123 nm, so each ring gives its own estimate of the electron wavelength.

A typical run records ring diameters at a series of anode voltages and then compares the measured wavelength with the de Broglie value calculated from each voltage. For departments buying from a physics instruments supplier in India, the tube slots into an existing S-series set-up and needs a filament supply of up to 6.3 V AC plus a high-voltage anode supply.

What to Specify When Ordering

• Whether you need the Teltron Tube Holder S to mount the tube.
• A power supply covering 6.3 V AC filament and up to 5 kV anode voltage.

Teltron Tube Holder D (Product Code: SLE/PHY/55) is a support stand used to hold Teltron D-series electron tubes and their accessories securely during electron-beam experiments in physics laboratories. College and senior-school physics departments use it as the base of the whole D-series set-up, because its cast light alloy stand carries a 360° rotating clamp and two base holes for the Teltron D Helmholtz Coils. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a physics instruments supplier to Indian and international buyers.

Specifications

What Is the Teltron Tube Holder D Used For?

The holder is the mechanical base of a Teltron D-series demonstration. The glass tube sits in the wishbone clamp, which turns through 360° so the tube screen can be angled towards the class, while a pair of Helmholtz coils fixes into the two base holes and stays lined up around the tube. This rigid arrangement is what makes electron-beam deflection, diffraction and specific charge (e/m) experiments with physics lab equipment repeatable from one lesson to the next.

Before switching on the tube supply, connect the 4 mm earthing socket in the pillar base as the included instructions describe. The three rubber feet keep the stand from sliding on a smooth bench, but it should still be placed away from the bench edge. Let a tube cool after use before loosening the clamp, and lift glass tubes by their bodies rather than by the connecting pins.

What to Specify When Ordering

• Tube series: this holder is for Teltron D-series tubes; laboratories using S-series tubes need the S version.
• Which D-series tubes you already have or are ordering with the holder.
• Whether the Teltron Helmholtz Pair of Coils D should be quoted together with the stand.
• Number of holders needed, usually one per demonstration station.

Supplier

Jain Scientific Equipments Private Limited trades as ScienceLab and supplies this Teltron-brand tube holder from Ambala, Haryana. Teltron is a separate brand, so the company sources the holder rather than producing it, and can quote it alongside the matching D-series tubes and coils so a department receives one consolidated offer. Company details are on the ScienceLab company profile.

Teltron Helmholtz Pair of Coils D (Product Code: SLE/PHY/56) is a pair of Helmholtz coils used to generate a uniform magnetic field perpendicular to the axis of Teltron D-series tubes in electron-beam experiments. University and senior-school physics laboratories use it with an EM ratio apparatus set-up; the coils have 320 turns and reach a maximum field of approximately 10 mT. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Are Teltron Helmholtz Coils D Used For?

Two identical coils set up in Helmholtz geometry give a nearly uniform field in the space between them, which is where a D-series tube sits. When current flows, the electron beam inside the tube bends into a curve, and by recording the coil current and the tube’s accelerating voltage students can work through a specific charge electron experiment to estimate e/m. The same pair can also be arranged to give a vertical field or a field coaxial with the tube, so one set of coils covers several deflection studies.

Keep the coil current at or below 1.0 A for continuous running; 1.5 A is allowed for up to 10 minutes and 2 A for up to 3 minutes, after which the coils should rest. An ammeter in series makes it easy to stay within these limits. For scale, the approx. 10 mT maximum is about 300 times weaker than the roughly 3 T field of an MRI scanner.

What to Specify When Ordering

• Tube series: these coils suit Teltron D-series tubes; an S-series version is listed separately.
• Whether you also need the Teltron Tube Holder D, whose base has holes for fixing the coils.
• The DC supply and ammeter you will use to drive and monitor the coil current.
• Number of coil pairs, one per demonstration set-up.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies this Teltron-brand coil pair from Ambala, Haryana. Because Teltron is an outside brand, the company sources the coils and quotes them together with the tube holder and D-series tubes when a department needs the complete arrangement.

Cylinders, Metal (Set of 6) (Product Code: SLE/PHY/57) is a set of six precision metal cylinders used to measure and compare the density of different metals in physics practicals. Each cylinder has a 10 mm diameter and is made of a different metal — brass, lead, iron, copper, aluminium or zinc — and the set comes in a wooden block. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as physics practical equipment for CBSE and other syllabi.

Specifications

What Are Metal Density Cylinders Used For?

The classic exercise is to find the density of each metal from its dimensions. Students measure the diameter and length of a cylinder with a vernier caliper, work out the volume as πr²h, weigh the cylinder on a balance and divide mass by volume. Repeating this for all six metals shows clearly why a lead cylinder feels so much heavier than an aluminium one of the same diameter.

The same cylinders can be lowered into a measuring cylinder of water to find volume by displacement, letting a class compare the geometric and displacement methods and discuss measurement error. Return each cylinder to its place in the wooden block after use to avoid dents, and have students wash their hands after handling the lead piece.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of this cylinder set and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Because the maker supplies schools, colleges, dealers and importers directly, a lost or damaged cylinder can be raised with the same team that made the set — ask us about a replacement. Read more on the ScienceLab company profile.

Related Physics Lab Equipment

Other apparatus needed for a density practical:

• Caliper Vernier (Metal) — measures cylinder diameter and length for the volume calculation.
• Triple-Beam Balance — weighs each cylinder to find its mass.

Metal Density Cubes (Set of 6) (Product Code: SLE/PHY/58) is a set of six equal-sized metal cubes used to show how density differs from one metal to another in physics and general science lessons. Because every cube has a 20 mm side, students can compare brass, lead, zinc, copper, aluminium and iron simply by weighing them, a staple of school physics lab equipment in India. The set is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Metal Density Cubes Used For?

Equal volume is the whole point of this set. Since each cube measures 2 cm along every edge, its volume is 8 cm³, so dividing the mass in grams by 8 gives the density in g/cm³ directly. Before weighing, ask students to rank the cubes by feel and then check their predictions on a balance — the gap between aluminium and lead usually surprises them.

The cubes also support class 9 density and relative density lessons in a science lab kit, and older students can measure the edges with a vernier caliper to confirm the volume rather than assuming it. Keep the six cubes together in a labelled tray or box, and remind learners to wash their hands after handling lead.

What to Specify When Ordering

• Set size: this six-cube set includes zinc; the seven-cube Metal Density Cube Set adds steel and tin instead of zinc.
• Number of sets, for example one per student group.
• Whether a balance or vernier caliper should be quoted with the cubes.

OEM Manufacturer

These density cubes come from Jain Scientific Equipments Private Limited, which trades as ScienceLab and acts as their OEM (original equipment manufacturer). They are produced at the company’s own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader, so schools, dealers and importers deal with the maker for quotations and repeat orders. Company background is on the ScienceLab profile page.

Metal Density Cube Set (Product Code: SLE/PHY/59) is a set of seven 20 mm metal cubes used to investigate density and identify metals by measurement in physics, chemistry and materials classes. It covers brass, lead, steel, copper, aluminium, iron and tin, so learners can compare iron with steel as well as very light and very heavy metals in one physics experiment kit for school. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is a Metal Density Cube Set Used For?

A popular use is the “identify the metal” challenge: a group is handed one cube, measures its edges, weighs it, calculates density and matches the answer against data-book values. With a 20 mm edge the volume works out to 8 cm³, which keeps the arithmetic manageable for younger students while still rewarding careful weighing.

Including both iron and steel makes a useful teaching point: their densities are so close that density alone cannot always separate an element from its alloy, which opens a discussion about how alloys are told apart using other properties. Tin and lead, both soft metals, show that similar-feeling materials can still differ greatly in density. Students should wash their hands after handling the lead cube.

What to Specify When Ordering

• Seven-cube set (with steel and tin) or the six-cube set that includes zinc.
• Number of sets for your practical groups.
• Any balance, caliper or measuring cylinder to be quoted alongside.

OEM Manufacturer

Stackable Leads (Product Code: SLE/PHY/60) are black 4 mm stackable connecting leads used to wire power supplies, meters and components together in physics and electronics practicals. Each lead is 500 mm long, and the stackable design lets another lead plug into the back of the first, so several connections can share one terminal — everyday physics lab equipment for schools. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Black Stackable Leads Used For?

By convention, black leads carry the negative, 0 V or common-return side of a circuit. Teaching students to take every black lead back to the supply’s negative terminal makes a circuit on the bench easy to check against its diagram, and it cuts down wiring mistakes when meters are added. That habit carries straight into an Ohm’s law experiment kit or any series-and-parallel investigation.

Stacking is what saves time: when two branches must meet at the same terminal, the second black lead plugs into the back of the first rather than needing an extra connector. Pull a lead out by its plug body, not the cable, and set aside any lead whose plug has become loose or whose insulation is damaged.

What to Specify When Ordering

• Colour: this listing is black; red and yellow stackable leads are listed separately.
• Quantity of each colour per bench or per student group.
• Length: each lead is 500 mm, so check that it spans your usual bench layout.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, is the OEM (original equipment manufacturer) of these leads and makes them at its own licensed factory at Saha, Ambala, Haryana, India. Because the black, red and yellow versions come from the same maker, a school can order a matched colour set in one quotation and reorder any single colour later. See the ScienceLab company profile for more about the company.

Related Physics Lab Equipment

Leads and instruments often ordered together:

• Stackable Leads Red — the positive-side partner to the black lead.
• Stackable Leads Yellow — a third colour for marking a separate branch or meter link.
• Crocodile Clips & Leads — for connecting to components that have no 4 mm socket.
• Digital Multimeter — measures the current and voltage in circuits wired with these leads.
• Power Supply Variable — a bench supply to power the circuit.

More items are in Physics Lab Equipment.

Frequently Asked Questions

What length and plug size are the Stackable Leads?
The Stackable Leads are 4 mm stackable leads with a length of 500 mm. The 4 mm size is the common socket size on school power supplies, meters and component boards.

What colour are the Stackable Leads in this listing?
The Stackable Leads listed under SLE/PHY/60 are black. Red and yellow Stackable Leads are listed separately, so a lab can colour-code negative, positive and branch connections.

What does “stackable” mean on the Stackable Leads?
Stackable means another lead can plug into the back of a Stackable Leads plug, so two or more connections can share one terminal without an extra junction block or adapter.

Stackable Leads Red (Product Code: SLE/PHY/61) is a red 4 mm stackable lead used to make the positive-side connections in laboratory circuits, from the supply’s positive terminal to switches, meters and components. It measures 500 mm, and its stackable plug accepts a second lead in its back, so one positive terminal can feed several branches of an AC DC circuits experiment. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Red Stackable Leads Used For?

Red is the conventional colour for the positive side of a DC circuit, so a red lead signals “this goes to plus” before anyone traces the wire. Polarity matters most when ammeters, voltmeters, diodes and electrolytic components are in the circuit; with all positive links in red, a teacher can glance along a bench and spot a reversed meter before it is switched on.

When a circuit has several parallel branches, the red leads for each branch can be stacked on the supply’s positive socket instead of being squeezed into a terminal. Keep red and black leads hung separately on a lead rack after the lesson, so the next class picks up correctly coloured pairs without sorting.

What to Specify When Ordering

• How many red leads are needed, usually matched one-for-one with black leads.
• Whether yellow leads are also required for branch or meter connections.
• Delivery location and whether the leads are part of a larger lab order.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, a registered MSME manufacturer (Udyam UDYAM-HR-01-0003714) and the OEM (original equipment manufacturer) of these red leads, made at its own licensed factory at Saha, Ambala, Haryana, India. Export consignments go out under Importer-Exporter Code AAECJ8618A (DGFT), so dealers and importers abroad buy from the same source as Indian schools. More is on the ScienceLab profile page.

MES Bulb Holder (Product Code: SLE/PHY/62) is a lamp holder for MES (miniature Edison screw) lamps, used to add a small bulb to series and parallel circuits in school science laboratories. Its screw terminals let students attach wires quickly without soldering, and 10 mm fixing centres allow it to be screwed onto a board or base, which suits any electricity experiment kit for schools. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is an MES Bulb Holder Used For?

A bulb in a holder is often the first “output” young learners meet: close the circuit and the lamp lights, break it and the lamp goes out. With two or three MES holders on the bench, a class can compare bulb brightness in series and in parallel, see what happens when one bulb is unscrewed, and use a lamp as a simple continuity tester for conductors and insulators.

Because the holder has screw terminals, stripped wire ends or crocodile clips connect directly; tighten each terminal just enough to grip the wire. Match the lamp’s voltage marking to the cells or supply in use, screw bulbs in gently by hand, and let a lamp cool before changing it. For permanent teaching boards, the 10 mm fixing centres let the holder be screwed down neatly beside switches and cell holders.

OEM Manufacturer

ScienceLab is the brand under which Jain Scientific Equipments Private Limited trades, and the company is the OEM (original equipment manufacturer) of this bulb holder, made at its own licensed factory at Saha, Ambala, Haryana, India. Dealers and importers stocking basic electricity items can source the holder straight from the manufacturer along with the rest of their circuit range. Visit the ScienceLab profile to learn more.

Miniature LDR (Product Code: SLE/PHY/65) is a 5 mm light dependent resistor used to sense light levels in physics and electronics experiments, from light-meter circuits to automatic night-lamp projects. Its resistance falls from about 1 MΩ in darkness to 2–4 kΩ at 100 lux, a change large enough to see clearly on a multimeter during physics practical work. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is a Miniature LDR Used For?

The simplest investigation connects the LDR to a multimeter on its resistance range and records readings as a lamp is moved closer or a hand shades the sensor; plotting resistance against light level shows how steeply the value falls. In an electronics context the LDR is placed in a potential divider with a fixed resistor, so the changing voltage can switch a transistor, LED or buzzer when it gets dark or bright.

Its peak spectral response at 540 nm lies in the green part of the spectrum, which makes it a good talking point about how sensors and the human eye respond to colour. Keep the power dissipated below 100 mW and the voltage within 150 V peak; in school circuits a series resistor keeps the current low. Solder the leads quickly, or mount the LDR in a component holder to avoid heat damage.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies this miniature LDR from Ambala, Haryana, as a component for school and college electronics and physics practicals. It is a sourced semiconductor part rather than an item the company makes, and it can be quoted alongside the meters, holders and leads a sensor practical needs. Company details are on the ScienceLab profile page.

Stackable Leads Yellow (Product Code: SLE/PHY/66) is a yellow 4 mm stackable lead used to pick out a separate branch, meter connection or signal line in a laboratory circuit, so it is never confused with the red and black supply leads. It is 500 mm long and stacks with other 4 mm leads on a shared terminal, keeping physics lab instruments clearly wired. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Yellow Stackable Leads Used For?

Once a circuit grows beyond a single loop, two colours are not enough. A yellow lead can mark the voltmeter connections across a component, the second branch of a parallel circuit, or the input signal to an oscilloscope or amplifier board, so a student tracing a fault always knows which wire belongs to which part of the diagram.

Teachers often agree a class rule — red to positive, black to negative, yellow for measurement or branch links — and write it into worksheets, which makes marking practical set-ups much quicker. As with any lead, inspect the plugs and insulation before use and coil leads loosely for storage rather than knotting them.

OEM Manufacturer

These yellow leads are made by Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), which trades as ScienceLab and is their OEM (original equipment manufacturer). Manufacturing is carried out at its own licensed factory at Saha, Ambala, Haryana, India — premises at 449, HSIIDC Industrial Area covered by Factory Licence AMB-ONLINE-CHD-J-414. Schools, colleges, dealers and importers order factory-direct; see the ScienceLab profile for more.

Related Physics Lab Equipment

Leads and meters that pair with yellow branch leads:

• Stackable Leads Red — positive-side leads for the supply connections.
• Stackable Leads — black leads for the negative or common return.
• Banana Plug Connectors Leads — an alternative set of plug-ended connecting leads.
• Standard Digital Multimeter — the meter a yellow measurement lead typically runs to.
• Ammeter Voltmeter — for reading current and voltage in branch circuits.

More apparatus is in Physics Lab Equipment.

Frequently Asked Questions

What are the Stackable Leads Yellow used for?
The Stackable Leads Yellow mark a connection that is neither supply positive nor negative, such as a meter link, a parallel branch or a signal line, keeping complex circuits easy to trace.

What length are the Stackable Leads Yellow?
The Stackable Leads Yellow are 500 mm long with a 4 mm stackable plug, the same length as the black and red stackable leads in the ScienceLab range.

Do the Stackable Leads Yellow work with red and black stackable leads?
Yes. The Stackable Leads Yellow share the 4 mm stackable format of the red and black versions, so all three colours can be plugged into each other on one terminal.

Crocodile Clips & Leads (Product Code: SLE/PHY/67) are connecting leads with a crocodile clip at each end, used to make quick, temporary connections to component legs, bare wires, electrodes and terminals in school electricity experiments. They come as a pack of 20 leads, each 460 mm long — enough to equip several bench groups for an electricity experiment kit in school. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Crocodile Clip Leads Used For?

Crocodile leads connect things that have no socket. Students clip them onto the metal strips of an electrolysis cell, the legs of a resistor, the zinc and copper plates of a fruit cell or a test sample in a conductor-and-insulator experiment, then join the other end to a bulb holder, meter or cell. Because both ends are clips, the same lead works anywhere in the circuit.

For a firm contact, clip onto bare, clean metal rather than insulation, and avoid prising the jaws too wide. After the lesson, count the pack back in and store the leads loosely coiled so the cables and clip joints are not strained.

OEM Manufacturer

Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, is the OEM (original equipment manufacturer) of these crocodile clip leads and makes them at its own licensed factory at Saha, Ambala, Haryana, India.

Knife Switch – Single Pole, Single Throw (Product Code: SLE/PHY/68) is a knife switch on a plastic base used to open and close a single circuit in electricity practicals, with an exposed blade that shows at a glance whether the circuit is made or broken. Its poles and blade are brass to give good electrical connections, which makes it a dependable control in an Ohm law experiment kit. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is a Single Pole Knife Switch Used For?

A single-pole, single-throw switch has one job: connect or disconnect one line of a circuit. The knife pattern is popular in teaching because the moving blade is visible, so students see the physical gap that stops the current, which links the circuit symbol for a switch to the real object. It is the usual choice for switching the supply in resistance, Ohm’s law and heating-effect experiments.

Open the switch between readings so resistors and wires do not heat up and change the results. When closing, push the blade fully into the jaw so the brass parts meet firmly; a half-seated blade gives a poor contact and flickering meter readings. Operate the switch by its handle and keep fingers clear of the exposed metal when the circuit is live.

What to Specify When Ordering

• Switch pattern: this is single pole, single throw; double-pole knife switches are listed separately.
• Quantity per lab, typically one per circuit board or student pair.
• Any leads, meters or holders to be quoted with the switches.

Supplier

Frequently Asked Questions

What voltage does the Electric Motor need?
The Electric Motor operates on 1.5 to 4.5 V DC, so it runs from a single 1.5 V cell up to three cells in series. Running it above 4.5 V is outside the listed operating range and can overheat the motor.

What are the dimensions of the Electric Motor?
The Electric Motor has a 20 mm body diameter, measures 15 mm across its two flats, has a 9 mm long shaft of 2 mm diameter and weighs approximately 17 g, which keeps it light enough for small models and robots.

Which way does the Electric Motor rotate?
Viewed from the shaft end, the Electric Motor rotates counter-clockwise as listed. As with other DC motors, swapping the two supply connections reverses the direction, which students can use to show how current direction changes the motion.

How is the Electric Motor connected and mounted?
The Electric Motor has solder tag terminals for wire connections and two flat sides that let it sit on a PCB or flat panel. Solder leads quickly to avoid heating the tags, or clip crocodile leads on for temporary classroom circuits.

Who supplies the Electric Motor?
The Electric Motor is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. It is a sourced miniature DC motor that the company provides with its physics and STEM items for schools, colleges and dealers.

Can schools order the Electric Motor in quantity?
Yes, the Electric Motor can be ordered in quantity for class projects, workshops and dealer stock, for delivery in India and international markets. Send the number of motors and your location through the enquiry cart or contact page for a quotation.

Potentiometer (Product Code: SLE/PHY/74) is a slide-wire potentiometer used to compare the emf of cells and measure potential differences by the null method in school and college physics laboratories. A 24 SWG constantan wire runs along a metre scale divided in cm and mm between stout plated brass end plates, and a jockey is 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 Slide-Wire Potentiometer Used For?

A steady driver cell connected across the wire sets up a uniform fall of potential along it. Students then use the jockey to find the balance point for a second cell or circuit, read the balancing length on the scale, and compare emfs, find the internal resistance of a cell or measure a small potential difference without drawing current at balance.

These experiments appear in most senior-secondary syllabi, which makes the potentiometer standard physics practical equipment for CBSE and state-board labs as well as first-year college courses. Press the jockey gently and lift it before moving along the wire; dragging it while pressed scratches the constantan and spoils the uniform resistance per centimetre. Keep the driver current low so the wire does not warm up during a reading.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this potentiometer. The company makes it at its own licensed factory at Saha, Ambala, Haryana, India, rather than buying it in from a trader, and supplies it factory-direct to schools, colleges, dealers and importers. Replacement jockeys and other spares are handled by the manufacturer itself — ask us when you order. More background is on the ScienceLab company profile.

A complete potentiometer circuit needs a few more items on the bench:

• Jockey with Insulated Handle (Single) — a spare or replacement jockey
• Moving Coil Galvanometer — the null detector for finding the balance point
• Rheostat — to set the driver current through the wire
• One Way Key — to switch the driver circuit on only while reading
• Potentiometer, 10 wire — a longer-wire model for finer balance lengths

Frequently Asked Questions

What is included with the Potentiometer?
The Potentiometer comes mounted on a polished hardwood baseboard with its 24 SWG constantan wire, metre scale, plated brass end plates and 4 mm socket terminals, and a jockey is included. Cells, galvanometer, rheostat and connecting leads are ordered separately.

What wire does the Potentiometer use?
The Potentiometer uses 24 SWG constantan wire stretched along a metre scale divided in centimetres and millimetres. Constantan is chosen because its resistance changes very little with temperature, giving a steady potential gradient along the wire during an experiment.

How large is the Potentiometer?
The Potentiometer measures approximately 1.13 m × 80 mm × 50 mm, so it needs a bench length of just over a metre. Leave space beside it for the driver cell, galvanometer, rheostat and key used in the circuit.

Who manufactures the Potentiometer?
The Potentiometer is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Schools, dealers and importers receive quotations and repeat-order support directly from the manufacturer.

Is a calibration certificate available for the Potentiometer?
The Potentiometer works by the null method, with results taken from balance lengths on its scale. If your institution needs a calibration certificate or test report for it, please discuss the requirement with us through the contact page before ordering.

What should a quotation request for the Potentiometer include?
A quotation request for the Potentiometer should give the quantity, the delivery location, and whether you also need spare jockeys, galvanometers, rheostats or keys. With those details the manufacturer can quote a complete set for your physics lab in one reply.

Wheatstone Bridge Four Gap (Product Code: SLE/PHY/75) is a metre-scale slide-wire bridge used to measure unknown resistances and compare resistors in school and college physics practicals. Broad, heavily plated brass strips with four gaps sit on a polished hardwood base, and 24 SWG constantan wire is stretched along the top of a metre scale marked in mm and cm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Four-Gap Wheatstone Bridge Used For?

With a known resistance in one gap and the unknown in another, a galvanometer connected between the bridge and the jockey shows zero deflection at the balance point, and the two lengths of wire on either side give the ratio of the resistances. The extra gaps allow more elaborate set-ups, such as the Carey Foster arrangement for comparing two nearly equal resistances, in which the resistors are interchanged to cancel end errors.

Typical practicals include finding the resistance and specific resistance of a wire and checking the laws of resistors in series and parallel, which makes this a practical Wheatstone bridge experiment kit once a cell, key, galvanometer and resistance box are added. Tighten the terminals firmly, tap the jockey rather than sliding it along the wire, and repeat each balance with the resistors swapped for a more reliable mean.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM of this four-gap bridge and produces it at its own licensed factory at Saha, Ambala, Haryana, India. ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), and the factory at 449, HSIIDC Industrial Area, Saha operates under Factory Licence AMB-ONLINE-CHD-J-414. Laboratories and dealers deal with the manufacturer itself for quotations, repeat orders and spare jockeys — details are on the company profile.

Frequently Asked Questions

What is the Wheatstone Bridge Four Gap used to measure?
The Wheatstone Bridge Four Gap is used to measure an unknown resistance by balancing it against a known one, and to find the specific resistance of a wire. Its four gaps also allow comparison of two nearly equal resistances by the Carey Foster method.

What are the dimensions of the Wheatstone Bridge Four Gap?
The Wheatstone Bridge Four Gap measures 1130 × 80 × 50 mm. Its metre scale, marked in millimetres and centimetres, runs under the 24 SWG constantan wire, so allow a bench space of a little over a metre plus room for the other circuit items.

What comes with the Wheatstone Bridge Four Gap?
The Wheatstone Bridge Four Gap comes with a jockey, fitted with its plated brass strips, constantan wire, metre scale and 4 mm socket terminals on the hardwood base. The galvanometer, resistance box, cell, key and leads are ordered separately.

How should the bridge wire be looked after?
On the Wheatstone Bridge Four Gap, tap the jockey onto the constantan wire and lift it before moving, because sliding it while pressed scratches the wire. Keep the brass strips and terminals clean and dry, and store the bridge flat so the wire stays taut.

Can we order Wheatstone bridges for a whole lab?
Yes, the Wheatstone Bridge Four Gap can be ordered in class quantities. Send the number of bridges, any matching galvanometers or resistance boxes, and your delivery location through the enquiry cart or contact page, and the manufacturer will quote the full set.
