What Is the Hand-Wheel Driving Unit Used For?
The unit lets students supply mechanical energy by hand and watch it drive other apparatus. Belted to a small dynamo, it turns the armature fast enough to light a lamp or deflect a meter, showing mechanical energy becoming electrical energy. Connected to a line shaft, flywheel or model pump, it demonstrates how power is transmitted by belts and pulleys and how a spinning flywheel stores energy, and it also drives eddy current demonstrations in which a spinning disc is slowed by magnets.
The pulley ratio is a lesson in itself: the 75 mm pulley driving the 20 mm pulley makes the smaller one turn 3.75 times for every turn of the larger, so students can relate diameters to speed. Hold or clamp the base firmly on the bench, keep belts properly tensioned, and turn the hand wheel smoothly rather than in jerks. Used with a dynamo, it makes a hands-on physics demonstration kit for energy conversion topics.
What to Specify When Ordering
- The quantity, for example one per demonstration bench or student group.
- Which apparatus it will drive (dynamo, eddy current unit, flywheel or pump) so matching items can be quoted together.

Eddy Current Unit 120 mm
Eddy Current Unit 120 mm (Product Code: SCI-1529/013) is a physics demonstration apparatus used to show how eddy currents induced in a moving conductor oppose its motion in electromagnetism lessons. Its 120 mm aluminium disc has a 20 mm driving pulley for the hand-wheel driving unit, and powerful circular magnets on a pivoted arm swing over or away from the disc, giving a clear electromagnetic induction demonstration. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
Specifications
| Parameter | Detail |
|---|---|
| Purpose | Demonstration of eddy currents |
| Disc | Aluminium, 120 mm diameter |
| Driving pulley on disc | 20 mm |
| Magnets | Powerful circular magnets |
| Magnet mounting | Pivoted arm, so the magnets can be moved over or away from the disc as required |
| Drive | Used in conjunction with the hand-wheel driving unit |
| Product code | SCI-1529/013 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Eddy Current Unit Used For?
With the magnets swung away, a few turns of the hand wheel set the aluminium disc spinning and it coasts for a while. Swing the magnets over the disc and it slows down sharply: the changing magnetic field induces circulating (eddy) currents in the aluminium, and by Lenz's law those currents create a field that opposes the motion. Students can also feel the hand wheel become harder to turn when the magnets are in place, which links the effect to energy being converted into heat in the disc.
Because aluminium is not attracted to a magnet, the demonstration makes clear that the braking comes from induction, not ordinary magnetic attraction. Teachers use it to introduce real applications such as eddy current brakes, induction meters and the damping of moving-coil instruments. Keep the magnets away from phones, watches and cards, and check that the belt runs straight before each lesson.
What to Specify When Ordering
- Whether you also need the Hand-Wheel Driving Unit, which the unit is designed to be used with.
- The number of units, for a demonstration bench or several student groups.
- Whether a drive belt should be included, as it is not mentioned in the listing.

Frequently Asked Questions
How does the Eddy Current Unit 120 mm demonstrate eddy currents?
In the Eddy Current Unit 120 mm, an aluminium disc is spun and the magnets are then swung over it. The disc slows sharply because currents induced in the aluminium produce a magnetic field that opposes the motion, a direct illustration of Lenz's law.
What drives the Eddy Current Unit 120 mm?
The Eddy Current Unit 120 mm is designed to be used with the hand-wheel driving unit. The disc carries a 20 mm driving pulley, so turning the hand wheel spins the disc quickly enough for the braking effect to be clearly seen.
Why is the disc of the Eddy Current Unit 120 mm made of aluminium?
The 120 mm disc of the Eddy Current Unit is aluminium because it conducts electricity well but is not attracted to magnets. Any braking students see therefore comes from induced eddy currents rather than from ordinary magnetic attraction.
Can the magnets on the Eddy Current Unit 120 mm be moved?
Yes. The powerful circular magnets of the Eddy Current Unit 120 mm are carried on a pivoted arm, so they can be moved over the disc or away from it as required, letting students compare free spinning with magnetic braking.
Who manufactures the Eddy Current Unit 120 mm?
The Eddy Current Unit 120 mm is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Buyers order it, and its matching hand-wheel drive, directly from the manufacturer.

| Product code | SCI-1531/014 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is the Large Motor/Generator Used For?
Connected to a low-voltage DC supply, the machine runs as a motor and, through its V pulley and belt, drives other apparatus. Turned by an external drive instead, it works as a dynamo and produces a voltage that students can read on a meter. Showing the same machine doing both jobs is one of the clearest ways to explain that motors and generators share the same principle, run in opposite directions of energy conversion.
For quantitative work, pair it with a smaller motor/generator: drive one with the other, meter the voltage and current on each side, and compare power in with power out to discuss losses and efficiency between larger and smaller machines. Keep the supply within the 2 to 6 V range, align the belt so it runs true, and avoid over-tightening it, which loads the bearings and wastes power.
What to Specify When Ordering
- Whether you also need the Small Motor/Generator for input/output comparison experiments.
- The number of units for your demonstration bench or student groups.
- Any DC supply and meters you want quoted, checked against the 2 to 6 V rating.

It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.
Specifications
| Parameter | Detail |
|---|---|
| Motor rating | 1.5 to 4.5 V |
| Supplied with | Driving belt |
| Designed for use with | The large motor/generator |
| Experiment | Comparing power input and output by driving each machine in turn with the other and metering voltages and currents |
| Product code | SCI-1435/015 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is the Small Motor/Generator Used For?
The unit is built for a classic energy-transfer practical. Belt it to the large motor/generator and power the large machine as a motor, so the small one is driven as a generator feeding a lamp or resistor. With an ammeter and voltmeter on each side, students calculate electrical power in and power out (voltage multiplied by current) and express the output as a percentage of the input to find the efficiency.
Next, swap the roles: supply the small machine within its 1.5 to 4.5 V rating so it drives the large one, and repeat the readings. Comparing the two results opens a discussion on friction, heating, belt slip and why machines of different size behave differently. Start from a low voltage and increase it gradually, and keep the belt clean and correctly aligned.
What to Specify When Ordering
- Whether you already have the large motor/generator or need it quoted with this unit.
- The number of sets, for example one pair per student group.

What Is the Desktop pH Meter Used For?
A desktop pH meter gives a numerical reading where indicator paper only gives a colour. Students and technicians use it to check the pH of acids, bases and buffer solutions, follow the change in pH during an acid-base titration to plot a titration curve, test drinking water and effluent samples, and monitor pH in enzyme and fermentation experiments. The mV mode supports electrochemistry work with a suitable electrode, and the temperature reading helps record the conditions of each measurement.
Calibrate at the start of each session with standard buffers; the automatic buffer recognition identifies them and completes the calibration. Rinse the electrode with distilled water between samples and blot it gently rather than wiping it. The support stand holds the electrode steady above the beaker so both hands stay free, and the electrode should be kept moist in its storage solution when the meter is not in use.
What to Specify When Ordering
- Whether a pH electrode and temperature probe should be quoted, as the listing only mentions the support stand as included.
- Calibration buffer solutions, if you need them supplied with the meter.
- Ask us to confirm the mV measuring range, which is not stated in the listing.

What Is a 250 ml Round Bottom Flask Used For?
The curved wall of a round bottom flask spreads heat evenly, which is why it is the standard vessel for boiling and reflux work. At 250 ml it is the size most students handle in organic practicals such as preparing an ester under reflux, carrying out a simple distillation, or dissolving and heating reagents before crystallisation. Borosilicate glass copes with the heating involved and resists the acids, alkalis and solvents used in these experiments.
A round bottom flask cannot stand on its own, so clamp it by the neck to a retort stand or seat it in a heating mantle. Fill it no more than about half full for boiling and add anti-bumping granules for smooth boiling. Always take the polypropylene stopper out before heating — a closed flask must never be heated — and use the stopper afterwards to cover the cooled contents.
What to Specify When Ordering
- The capacity: this listing is 250 ml, and a larger flask is also available.
- The number of flasks, including spares to cover breakage over the year.
- Any support and heating accessories to quote together, such as a heating mantle, clamp or stand.

Its 500 ml capacity handles bigger batches than student-scale flasks, and an interchangeable polypropylene stopper closes it for storage or transfer, making it versatile chemistry lab glassware. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
Specifications
| Parameter | Detail |
|---|---|
| Capacity | 500 ml |
| Material | Borosilicate glass |
| Resistance | Heat resistant and chemical resistant |
| Stopper | Interchangeable polypropylene stopper, fitted |
| Bottom | Round |
| Product code | SCI-1347/018 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is a 500 ml Round Bottom Flask Used For?
The 500 ml size is chosen when the volume of liquid is too large for a smaller flask to boil safely. Typical jobs include distilling water or a solvent for reuse, steam distillation of plant material such as cloves to extract an essential oil, refluxing a larger preparation for a class demonstration, and acting as the receiving flask at the end of a distillation train. In pharmacy and research labs it is also used to heat and dissolve larger quantities of material before filtration.
Before each use, check the glass for chips or star cracks, and warm the flask gradually rather than applying full heat at once. Let it cool naturally before washing, because pouring cold water into hot glass causes thermal shock. Clean it with a flask brush and detergent, rinse with distilled water and dry it upside down, then refit the polypropylene stopper for storage.
What to Specify When Ordering
- The capacity required: this flask is 500ml, and a smaller size is also listed.

What Is the 50 mm Tripod Stand Used For?
A small tripod is used for small-scale heating, where a full-size stand would be too wide for the vessel. Typical uses include warming a little solution in a small beaker on a piece of wire gauze over a spirit lamp, heating a crucible on a suitably sized pipe-clay triangle, or evaporating a few drops of a solution in a small dish to recover crystals. The three-legged frame keeps the vessel level and resists being knocked sideways.
The plastic caps on the legs protect polished or laminated bench tops, but they should be kept clear of the flame, so place the heat source centrally under the top. Let the stand cool before moving it, and handle hot crucibles or dishes with tongs. Because the height is not stated in the listing, check that your spirit lamp or burner fits underneath before ordering.
What to Specify When Ordering
- The height you need, since the listing does not state it — ask us to confirm.
- Your preferred top material, as the listing mentions both mild steel wire and cast iron.
- Quantity, plus any gauze, spirit lamps or tongs to quote with the stands.
