Light Gates/Timing Gates (Product Code: SLE/PHY/230) is a pair of timer gates used to start and stop an electronic timer as a moving object passes, in school and college mechanics experiments. The two gates link to the timer through DIN connections, so the time between them is recorded electronically instead of with a hand-held stopwatch. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for motion and acceleration practicals.

Key Details

What Are Light Gates/Timing Gates Used For?

A light gate senses the moment an object breaks its beam. With two gates set a measured distance apart, the timer records how long a trolley, air-track glider or falling object takes to travel between them, giving an average speed. Passing a card of known length through the gates lets students work out speed at each gate, and from the change in speed, the acceleration.

For reliable readings, mount both gates so the card or object crosses the beam cleanly, measure the gap between them carefully, and run a few trial passes before recording results. Electronic timing removes human reaction time from the measurement, which is why light gates are standard mechanics lab equipment in India for Newton's laws, momentum and free-fall practicals.

What to Specify When Ordering

• The timer you will connect the gates to, so we can confirm the DIN connections suit its inputs.
• The number of pairs needed for your practical groups.
• Whether a timer, track or trolley should be quoted with the gates.

Light Guide Demonstrator (Product Code: SLE/PHY/231) is an S-shaped acrylic bar used to demonstrate total internal reflection and the principle behind optical fibres in school physics optics lessons. Measuring 220 x 20 x 20 mm, it is used with a raybox, and the bottom of the bar is painted white to aid visibility of the light path. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Light Guide Demonstrator Used For?

When a raybox beam is directed into one end of the bar, the light does not leak out at the bends. Each time it meets the acrylic surface at a large enough angle it is totally internally reflected, so it zig-zags along the S-shape and emerges from the far end. Students can see that light can be guided around corners, which is exactly how optical fibres carry telephone and internet signals.

For the clearest view, dim the room lights and align the beam squarely with the end face; the white-painted base helps the reflected path stand out. Wipe the acrylic with a soft, clean cloth and store it where it will not be scratched, because surface marks let light escape. It is a simple, durable piece of optics lab equipment for school and college physics departments across India.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) of the Light Guide Demonstrator. The company is incorporated under CIN U29309HR2020PTC087597, and production takes place at the company's licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414). Because the demonstrator is made by the manufacturer itself rather than bought from a trader, schools, colleges, dealers and importers receive it factory-direct, and replacement bars or repeat orders can be discussed with us directly. Read more on the ScienceLab company profile.

Line Shaft Unit (Product Code: SLE/PHY/232) is a base-mounted shaft and pulley unit used to show electrical energy being converted into potential energy, by winding up a weight on a cord, in school physics energy lessons. It is one of the separately available units of the Energy Transfer Kit, built on a 165 x 100 mm base with a 6 mm steel shaft and a 56 mm aluminium 'V' pulley. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Line Shaft Unit Used For?

In an energy-transfer lesson, an electrically driven unit turns the line shaft through its V pulley. The cord, fixed by the anchoring collar, winds onto the turning shaft and lifts a weight, so the electrical energy put in ends up stored as gravitational potential energy of the raised mass. Students can note the mass and the height gained to calculate that stored energy, then compare it with the electrical energy supplied to discuss efficiency and losses.

Because every unit in the Energy Transfer Kit shares the same 165 x 100 mm base, the line shaft lines up neatly beside the other units on the bench, and teachers can build different chains of energy conversion from the same set. It is a practical piece of school physics lab equipment in India for teaching energy stores and transfers.

What to Specify When Ordering

• Which other Energy Transfer Kit units you need to drive or extend the line shaft.
• The number of Line Shaft Units per lab or per student group.
• Whether a weight and cord should be quoted, as these are not listed with the unit.

Linear Air Track Blower (Product Code: SLE/PHY/233) is an electronically controlled air supply unit used to feed a steady flow of air to a linear air track in school and college mechanics laboratories. Its 700W motor runs on 220-240V 50Hz and delivers a constant volume and pressure through a flexible hose with a 30 mm internal diameter, helping experiments give more accurate results. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Linear Air Track Blower Used For?

The blower is the air source that makes an air track work. Once the hose is attached to the track's inlet and the unit is switched on, air escapes through the small holes along the track and the gliders float on a thin cushion, so friction almost disappears. Students can then study Newton's laws, collisions and the conservation of momentum with results that are much closer to theory than on a normal runway.

Because the unit keeps the volume and pressure of air constant, the gliders ride at a steady height throughout each run, which makes repeated timings consistent. Check that the hose is pushed fully onto the track inlet, stand the blower where its airflow and vibration will not disturb the track, and switch it on before placing gliders. We act as a physics instruments supplier in India for schools that already own, or are buying, an air track.

What to Specify When Ordering

• Your mains supply; the motor is rated 220-240V 50Hz, so tell us if your site differs.
• The air track the blower will feed, so we can check the 30 mm hose suits its inlet.
• The number of blowers needed (usually one per track in use at the same time).
• Whether light gates or a timer should be quoted for glider experiments.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab in Ambala, Haryana, supplies the Linear Air Track Blower to schools, colleges, engineering institutes and dealers in India and international markets. We can quote the blower on its own as a replacement air source, or together with a track and timing equipment as a complete set-up. Visit the ScienceLab company profile to learn more about us.

Magdeburg Hemisphere (Product Code: SLE/PHY/235) is a brass hemisphere apparatus used to demonstrate the existence of atmospheric pressure in school and college physics lessons. It has a diameter of 75 mm and is fitted with a stopcock and handle, so air can be drawn out and the halves then resist being pulled apart. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as educational physics lab equipment.

Specifications

What Is the Magdeburg Hemisphere Used For?

This apparatus recreates, on a bench scale, the famous 17th-century demonstration by Otto von Guericke in the town of Magdeburg. Wipe the rims clean and apply a thin film of vacuum grease, press the two halves together, and connect the stopcock to a vacuum pump. After pumping, close the stopcock and disconnect the pump: students will find the hemispheres very hard to separate, even though nothing seems to be holding them.

The explanation is that air outside pushes on the whole surface of the sphere, while there is very little air left inside to push back. Opening the stopcock lets air rush in and the halves come apart easily, which makes the role of atmospheric pressure obvious. Keep the rims free of dents and grit, and store the brass hemispheres dry so they continue to seal well between demonstrations.

What to Specify When Ordering

• The version: this brass 75 mm set with stopcock, or the larger plastic model with wooden handles.
• Whether a hand or electric vacuum pump and tubing should be quoted with it.
• The number of sets for demonstration or group practicals.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of this brass Magdeburg Hemisphere and makes it at its own licensed factory at Saha, Ambala, Haryana. The company is a registered MSME enterprise with manufacturing as its major activity (Udyam UDYAM-HR-01-0003714), and its export shipments are handled under Importer-Exporter Code AAECJ8618A (DGFT). Schools, colleges, dealers and importers buy directly from the maker, and repeat orders or replacement parts can be discussed with us at any time. See the ScienceLab company profile for more.

Magdeburg Hemisphere, Plastic (Product Code: SLE/PHY/236) is a plastic hemisphere model used to show the force of atmospheric pressure in school science and physics classes. At 120 mm in diameter it is a large, light model, and its wooden handles give students a firm grip when they try to pull the halves apart. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Plastic Magdeburg Hemisphere Used For?

This model turns an abstract idea into a tug-of-war. Once the air between the two halves is removed, two students each take a wooden handle and pull, and they find the hemispheres held together by the air pressing on them from outside. Letting air back in releases the halves at once, which shows clearly that it is the air, not any glue or catch, that was holding them.

Its 120 mm diameter gives a useful teaching point: the force from atmospheric pressure depends on the area it acts on, so a wider sphere is held more strongly than a smaller one. Plastic keeps the model light enough for younger pupils to handle. Keep the rims clean, avoid solvents and store it away from heat. It is a practical, lightweight option among physics lab equipment for schools in India.

What to Specify When Ordering

• The version: this 120 mm plastic model or the smaller brass set with stopcock.
• Whether you want us to confirm the air-removal method and quote a vacuum pump if needed.
• The number of models for classroom demonstrations or student groups.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) that makes this plastic Magdeburg Hemisphere at its own licensed factory in Saha, Ambala, Haryana. Rather than passing through a chain of traders, the model goes factory-direct to schools, colleges, dealers and importers in India and international markets, and quotations are prepared by the manufacturer itself. For repeat orders or replacement handles, ask us. More details are on the ScienceLab profile page.

Magnetic Activity Kit (Product Code: SLE/MG/24) is a compact set of ferrite magnets and fittings used to demonstrate magnetic poles, levitation by repulsion and field strength in middle- and secondary-school science lessons. It contains 5 anisotropic ferrite magnets, a rod, screw-on caps and washers, with instructions, making it an easy-to-use magnetism experiment kit for Indian classrooms. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Magnetic Activity Kit Used For?

The kit walks students through the core ideas of magnetism with one small set of parts. They first identify the N and S pole of each magnet, then arrange the magnets on the rod with like poles facing so that each one hovers above the next — levitation by repulsion — with the screw-on caps keeping everything on the rod. Adding or removing magnets and watching the gaps change leads naturally into how magnetic force weakens with distance.

Stacking magnets together shows how to make a stronger magnetic field, and simple tests through water, a sheet of card or plain air show that magnetic fields pass through liquids, solids and gases. Anisotropic ferrite magnets are magnetised along a preferred direction, which gives them a strong pull for their size, but ferrite is brittle, so handle the magnets gently and do not let them snap together.

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM manufacturer of the Magnetic Activity Kit and assembles it at the company's own licensed factory at Saha, Ambala, Haryana, India. Schools, science centres, dealers and importers buy the kit directly from the manufacturer.

If a magnet chips or a cap goes missing, ask us about spares; replacement-part and repeat-order enquiries are handled by the manufacturer itself. See our company profile for more about the business.

• Magnets, Ring — ceramic ring magnets for floating-magnet experiments.
• Super Floating Magnets Set — for comparing the strength of different magnets.
• Economy Magnet Kit — a boxed starter set with bar, horseshoe and donut magnets.
• Compass Plotting (Clear) — helps students confirm which end is the N pole.

More magnetism apparatus is listed in the Magnets category.

Frequently Asked Questions

What is included in the Magnetic Activity Kit?
The Magnetic Activity Kit (SLE/MG/24) contains 5 anisotropic ferrite magnets, a rod, screw-on caps and washers, together with instructions that guide students through each magnetism demonstration.

What does "anisotropic ferrite" mean?
The magnets in the Magnetic Activity Kit are anisotropic ferrite, a ceramic magnet material magnetised along a preferred direction during production. This gives a stronger pull for its size than non-oriented ferrite, but the material is brittle and should not be dropped.

Which experiments can students do with the kit?
The Magnetic Activity Kit demonstrates N and S poles, levitation by repulsion, the link between magnetic strength and distance, how to make a stronger magnetic field, and how magnetic fields pass through liquids, solids and gases.

How is levitation by repulsion shown?
In the Magnetic Activity Kit, magnets are arranged on the rod with like poles facing, so each one pushes against the next and hovers in the air. The screw-on caps keep the magnets on the rod during the demonstration.

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

How should the kit be stored?
Store the Magnetic Activity Kit with its magnets kept apart, away from computers, bank cards and other magnets. Avoid letting the ferrite magnets snap together, as the impact can chip their edges.

Can the kit be quoted for a whole school or for export?
Yes. ScienceLab quotes the Magnetic Activity Kit direct from the manufacturer for single classes, whole schools, dealers and importers in India and international markets. Share the number of kits and delivery city or port via the contact page.
