Long Cylindrical Spring (Resort) (Product Code: SCL1219/08) is a long helical spring in silver-coloured stainless steel, 20 mm in diameter and 3 metres long, specified for an elongation of 3 times. Laid on the floor or a long bench and stretched between two students, it carries pulses and waves slowly enough for a whole class to follow them, so transverse and longitudinal motion can be compared side by side. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and forms the heart of a wave motion kit for schools in India.

Specifications

Typical Use

With one student holding each end, a quick sideways flick sends a transverse pulse along the coils, while a sharp push along the spring's length sends a band of compression that models how sound travels. Holding one end firmly shows that a pulse returns inverted from a fixed end; letting that end move freely shows it returning the same way up. Shaking one end at a steady rate sets up standing waves, and the class can point out nodes and antinodes, measure the wavelength with a tape and time pulses to estimate wave speed.

Work on a smooth, clear floor or a long bench, keep the stretch within the specified elongation so the coils are not permanently deformed, and never let go of a stretched end suddenly. Easy to see from the back of the room, the spring earns its place in any physics demonstration kit in India.

Manufacturer

Jain Scientific Equipments Private Limited, known to schools by its trade name ScienceLab, produces this spring in Ambala, Haryana, alongside a wide range of apparatus for teaching waves, sound and mechanics. Visit the company profile to learn more about the business.

See the whole Lab Equipment category for more physics apparatus.

Frequently Asked Questions

How far can the spring be stretched?
It is specified for an elongation of 3 times. Staying within that limit keeps the coils evenly spaced and prevents permanent stretching.

Can it show both transverse and longitudinal waves?
Yes. A sideways movement of one end produces transverse pulses, and a push along the axis produces compressions and rarefactions.

What is it made of?
The spring is silver-coloured stainless steel with a cylindrical shape and a diameter of 20 mm.

How much space is needed for a demonstration?
It is 3 metres long before it is stretched, so a corridor, a long bench or a clear strip of classroom floor works best.

How can we stop it from tangling in storage?
Let the coils close up gently, tie the bundle loosely at a few points and store it in a box or bag so the turns cannot twist through each other.

Do you supply schools in bulk and abroad?
Yes. We quote class and bulk quantities for institutions and distributors in India and international markets; share the quantity and destination with your enquiry.

Newton's Pendulum (Newton's Cradle) (Product Code: SCL1321/09) is a row of suspended steel balls used to show how momentum and energy pass along a line of colliding bodies in school and college physics lessons. Its 5 steel balls, at least 15 mm across, hang on two 120 mm wires in a straight line, so a released end ball sends the far ball swinging while the middle ones stay still. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Newton's Cradle Used For?

Start by releasing a single end ball and ask the class to predict what will happen; then release two together and watch two leave from the far side. Discussing why the number of balls leaving always matches the number released leads students to see that both momentum and kinetic energy are conserved in these near-elastic collisions. Raising the first ball higher makes the far ball rise higher too, a neat link between potential and kinetic energy, and the gradual dying away of the motion opens a discussion of energy lost as sound and heat.

Place the cradle on a level bench, check that the balls hang in a straight line and just touch before you begin, and release the ball rather than pushing it. The two-wire suspension keeps each ball swinging in one plane, which is why the effect is so clear when the set is well aligned. It is a favourite demonstration model in physics lab equipment across India, for classroom lessons and science exhibitions alike.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of this Newton's cradle and makes it at its own licensed factory at Saha, Ambala, Haryana, India, rather than sourcing it from a trader. Schools, colleges, dealers and importers order it factory-direct, and replacement balls or wires for sets already in use can be requested from the manufacturer — ask us. For vendor registration, institutional buyers can record the company's GSTIN 06AAECJ8618A1ZT and its Legal Entity Identifier (LEI) 3358004HRD1JIVXKYX49. More about the company is on the company profile.

More demonstration apparatus is listed in our Lab Equipment category.

Frequently Asked Questions

How many balls does it have and how large are they?
The Newton's Pendulum (Newton's Cradle) has 5 steel balls with a minimum diameter of 15 mm. Each ball hangs on two wires 120 mm long, and the balls are aligned in a straight line on the support.

What happens if two balls are released together?
When two end balls of the Newton's Pendulum (Newton's Cradle) are released together, two balls swing out from the opposite end. The number leaving matches the number released because both momentum and kinetic energy are conserved in the collisions.

Why does the motion eventually stop?
The swinging of the Newton's Pendulum (Newton's Cradle) dies away because each collision is not perfectly elastic. A little energy is lost as sound and heat and to air resistance with every swing, so the motion gradually stops.

What should I do if the balls fall out of line?
If the balls of the Newton's Pendulum (Newton's Cradle) drift out of line, gently untwist the wires until every ball hangs in a straight row and just touches its neighbours. For a damaged wire, ask us about a replacement through the contact page.

Who manufactures the Newton's Pendulum (Newton's Cradle)?
The Newton's Pendulum (Newton's Cradle) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools and distributors receive quotations directly from the manufacturer.

Do you supply it for bulk and export orders?

Newton's Tube (Product Code: SCL1223/010) is a long, sealed glass tube used to show that light and heavy bodies fall together once air resistance is removed, in school and college physics demonstrations. At least 1,500 mm long, it holds a wedge, a piece of sponge and a 5 mm metal ball, and its lid carries a tap and an air-outlet connection for a vacuum pump. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as mechanics lab equipment.

Specifications

What Is the Newton's Tube Used For?

The demonstration runs in two stages. First, with the tube full of air, the teacher closes the tap, holds the tube upright and turns it over smoothly: the metal ball drops quickly while the sponge drifts down slowly, just as everyday experience suggests. Next, the air outlet is connected to a vacuum pump, the air is drawn out and the tap is closed before the tube is inverted again. This time the objects fall side by side, showing that without air resistance all bodies fall with the same acceleration.

Letting a little air back in and repeating shows the effect of air resistance returning step by step, which makes a strong closing question for the class. An evacuated glass tube must be handled with care: turn it in a controlled way, never knock it against the bench, keep students at a safe distance and wear eye protection while it is under vacuum. Wipe the glass clean before class so the falling objects are easy to see from the back of the room.

What to Specify When Ordering

• The tube diameter you need within the 30–100 mm range (the length is a minimum of 1,500 mm).
• Whether a vacuum pump and vacuum tubing should be quoted with the tube, as no pump is listed with it.
• The number of tubes and the delivery location, so packing for the glass can be planned.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Newton's Tube and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Because the tube comes from its maker rather than a trader, schools and distributors get quotations, packing advice and repeat orders straight from the source, and a replacement part can be requested if one is damaged — ask us. Read more on the about-us profile.

Related Lab Equipment

Items needed to evacuate the tube, plus alternatives for the same lesson:

• Vacuum Pump with Pressure Gauge — removes the air through the tube's outlet and shows the pressure reached.
• Vacuum Tubing — connects the air outlet to the pump.

Explore other items in the Lab Equipment category.

Frequently Asked Questions

What objects are inside the Newton's Tube?
The Newton's Tube contains a wedge, a piece of sponge and a metal ball of 5 mm external diameter. The contrast between the light sponge and the dense ball makes the effect of air resistance, and its removal, easy to see.

Is a vacuum pump supplied with the tube?
No pump is listed with the Newton's Tube. The tube connects through its tap and air-outlet connection to a separate vacuum pump, such as the Vacuum Pump with Pressure Gauge, using suitable vacuum tubing.

What diameter will the tube be?
The Newton's Tube is specified with a diameter of 30–100 mm and a minimum length of 1,500 mm. Tell us the diameter your syllabus or tender needs, and the exact dimensions will be confirmed in your quotation.

Can the demonstration be done without a vacuum?
Partly. With air inside, the Newton's Tube shows the sponge falling far more slowly than the metal ball, which demonstrates air resistance. The equal-fall result needs the air to be pumped out through the air outlet first.

What precautions apply to an evacuated glass tube?
Handle the evacuated Newton's Tube gently: turn it in a controlled way, avoid knocks and sudden temperature changes, keep observers at a safe distance and wear eye protection while the glass tube is under vacuum.

Who manufactures the Newton's Tube?
The Newton's Tube is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations for the tube, with or without a pump and tubing, come directly from the manufacturer.

Pascal's Sphere (Product Code: SCL1225/011) is a complete demonstration of Pascal's law: a hollow sphere with 10 equidistant nozzles, connected to a hand pump whose plunger applies pressure to the fluid inside. Push the plunger and fluid leaves every nozzle with equal force in all directions, showing that a change in pressure in a fluid is transmitted equally to all its parts. Supplied with instructions, it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its educational laboratory equipment in India for fluid-pressure lessons.

Specifications

Typical Use

The sphere is filled with water, the teacher pushes the plunger steadily, and thin jets spring from all the nozzles at once – upwards, downwards and sideways alike. Because the jets leave with equal force whichever way the nozzles point, students can see that the pressure applied at the pump is passed on undiminished throughout the liquid. The lesson leads naturally to hydraulic jacks, presses and vehicle brakes, where a small force on a small piston produces a large force on a larger one.

Carry out the demonstration over a sink or a large tray, and push the plunger smoothly rather than in jerks for even jets. After class, empty out the water, let the sphere and pump dry, and check that no nozzle is blocked, since a blocked opening spoils the symmetry of the display. Follow the supplied instructions for filling and use.

Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, builds this sphere in Ambala, Haryana, as one of several apparatus it makes for teaching pressure and fluids to secondary students. You can find out more from the company profile.

• Glass Beaker — a container of water for filling the sphere through its nozzles.
• Pascal’s Principle Demonstrator — an alternative apparatus for the same law.
• Set to Demonstrate Archimedes’ Principle/Law — the next step in the fluids syllabus, on buoyancy.
• Set of Capillary Tubes — shows another property of liquids, capillary rise.

More fluids and mechanics apparatus is in our Lab Equipment category.

Frequently Asked Questions

How many nozzles does the sphere have?
It has 10 equidistant nozzles, so jets appear in every direction when pressure is applied.

Which liquid should be used?
Clean water is the usual choice for classroom demonstrations. Use the instructions supplied with the apparatus for filling and operation.

Are instructions included?
Yes, the apparatus is supplied with instructions.

Why do the jets leave with equal force from every nozzle?
The plunger raises the pressure of the enclosed liquid, and that increase is transmitted equally in all directions, which is exactly what Pascal's law states.

What materials are the sphere and pump made from?
Materials are not listed in the current specification. Please ask through the contact page if your tender or purchase order needs them stated.

Can you supply several units for a school network or distributor?
Yes, bulk quantities can be quoted for institutions and distributors in India and international markets. Include the product code SCL1225/011.

Power Source For Teacher (Product Code: SCL1427/012) is a demonstration-table power unit with two separate outputs: an alternating (AC) source on one pair of terminals and a continuous (DC) source on the other pair. The output is adjustable from 2 to 24 V (minimum range) on a graduated control, supplies a maximum current of 5 A, and is protected against short circuits, while a built-in voltmeter and ammeter let the whole class see the voltage and current. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a practical power supply unit for lab demonstrations in India.

Specifications

Typical Use

From the front bench, a teacher can run the DC terminals into an electrolysis cell, an electromagnet or a resistance wire to show chemical, magnetic and heating effects of current, then switch to the AC terminals for a demonstration transformer or induction experiment. Because the meters are built in, students read the voltage and current straight from the unit while the teacher varies the setting, which makes Ohm's law and power calculations easy to follow in real time.

Good practice is to turn the control to its lowest setting before switching on, make all connections with the unit off, and raise the voltage gradually while watching the ammeter. If the short-circuit protection operates, switch off and check the wiring before trying again. Always plug into an earthed 220 V socket so the earth conductor can do its job.

Manufacturer

The unit is built by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and produces electrical demonstration apparatus for school and college physics. Further information is available on the ScienceLab company profile.

Vacuum Pump with Pressure Gauge (Product Code: SCL1429/013) is a mechanical or electrical installation with a minimum power of 90 W that both removes air from, and pumps air into, the apparatus used to study gas processes. Through its tap, air can be exhausted down to a pressure of 130 Pa, and by pumping, a pressure of up to 0.3 MPa can be obtained, while the pressure gauge lets the class follow each change. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for schools that want a single physics instruments supplier in India for pump and accessories.

Specifications

Typical Use

Connected to a glass bell on its sealed support, the pump draws out the air so students can watch a partly inflated balloon swell, water begin to boil at room temperature, or a ringing bell fade into silence as the medium for sound is removed. The same pump evacuates a Newton's tube for the free-fall demonstration and supports other experiments on gases where pressure is the variable being changed. In pumping mode it raises the pressure inside suitable apparatus, so the class can explore how a gas responds to compression.

Check hoses and seals before each lesson, close the tap to hold a vacuum once the gauge shows the pressure you want, and open it slowly to let air back in. Only pressurise vessels that are intended to take pressure – never ordinary thin glassware – and keep students behind a safe line when glass is under vacuum.

Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited in Ambala, Haryana, which supplies gas-law and pressure apparatus to schools and colleges. The company is incorporated under CIN U29309HR2020PTC087597 and manufactures at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414).

Glass Bell on The Support (Product Code: SCL1431/014) is a transparent glass bell with a handle, at least 200 mm in diameter and 250 mm high, standing on a plastic holder fitted with a sealing gasket. Placed over small apparatus and used with a vacuum pump, it forms a clear, sealed enclosure in which students can watch what happens as the air is taken away. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a school laboratory equipment supplier in India for air-pressure and vacuum lessons.

Specifications

Typical Use

Typical experiments under the bell include a partly blown-up balloon that swells as the surrounding air is pumped away, warm water that starts to boil at reduced pressure, and a small ringing device whose sound fades as the air thins. Once the bell has been evacuated, students can also try to lift it by the handle and feel how firmly the outside air presses it onto the gasket – a memorable way to show that atmospheric pressure is real and large.

Before each use, inspect the glass for chips or cracks and never evacuate a damaged bell. Keep the rim and the sealing gasket clean and free of grit so the seal holds, and let air back in slowly before lifting the bell off the support. Carry it with one hand on the handle and the other under the glass.

Manufacturer

This bell and support come from Jain Scientific Equipments Private Limited, the Ambala, Haryana company that sells its teaching apparatus under the ScienceLab name to schools in India and international markets. For company details, see the ScienceLab profile.

Digital Hygrometer - Thermometer (Product Code: SCL1235/015) is a digital device for measuring humidity and temperature, equipped with a measuring probe so that readings can be taken both inside and outside. It covers temperatures from -10 °C to +40 °C and relative humidity from 20-25% up to 80-95%, in a compact 20x100x150 mm body with the battery included. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is one of the simple digital measuring instruments in India's school labs that students can read at a glance.

Specifications

Typical Use

A class weather project is the classic use: students record indoor conditions on the display and outdoor conditions through the probe at the same time each day, then plot how temperature and humidity change with the weather and the season. The readings feed discussions on evaporation, why washing dries slowly on humid days, dew and human comfort. In biology the instrument checks conditions around germination trays or potted plants in transpiration work, and laboratory staff use it to keep an eye on humidity where hygroscopic chemicals or balances are stored.

After moving the unit from one room to another, allow the reading to settle before recording it. Keep the probe out of direct sun and rain for true air readings, stay within the stated temperature range, and replace the battery when the display becomes faint. As a practical addition to an environmental science kit for schools, it gives students real data rather than textbook values.

Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana, offers this instrument alongside its thermometers, barometers and other measuring apparatus for teaching laboratories. Company background is on the profile page.
