Kinetic Theory Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4617
Jlab Export is a leading Kinetic Theory Apparatus Manufacturer,and suppliers in India
Kinetic Theory Apparatus (code EL-SLE-4617) is a physics demonstration in which a DC motor agitates metal spheres inside a test tube, so a class can watch a working model of the kinetic theory of gases and of related effects such as air thinning with increasing altitude. Socket terminals on the apparatus take the electrical supply for the motor. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Kinetic Theory Models?
| Model | Listed details |
|---|---|
| This apparatus (EL-SLE-4617) | DC motor agitates metal spheres in a test tube; socket terminals for the motor supply |
| Kinetic Theory Model Polystyrene Piston | Motor running at 4–12 V DC vibrates a platform under many small steel balls in a transparent tube; supplied with balls and floats, whose weight stands for gas pressure |
| Kinetic Theory Model (perspex tube) | Metal spheres driven up a wide perspex tube by a vibrating piston; low-voltage motor in a box, with speed control |
| Kinetic Theory Model (large demonstration) | Large demonstration model with polystyrene balls; 6 V AC |
Choose this apparatus for a compact test-tube demonstration of molecular motion and the thinning of air with height. The polystyrene-piston model adds floats for showing pressure, and the perspex-tube model lists a built-in speed control.
What Is the Kinetic Theory Apparatus Used For?
The kinetic theory pictures a gas as a huge number of molecules in constant, random motion; their collisions with the container walls create pressure, and a higher temperature means a higher average molecular speed. In this apparatus the metal spheres play the part of molecules and the motor-driven agitation plays the part of heat: switch the motor on and the spheres bounce about the tube, colliding with each other and the walls. They crowd most densely near the bottom and thin out further up — a direct picture of why air is densest at ground level and thinner at altitude, as gravity keeps most of the air's molecules close to the ground. Where the supply can be raised within the motor's rating, stronger agitation sends the spheres faster and higher, modelling a rise in temperature. It fits class 11 physics on kinetic theory, class 9 science on the particle nature of matter, and introductory college physics and chemistry.
Keep the test tube upright and secure during a demonstration, run the motor only within its rated supply, and switch off before handling the tube or changing connections.
What to Specify When Ordering
- Power supply — state the DC source you plan to use, so JLab can confirm the motor rating and terminals.
- Quantity — the minimum order is 10 units.
- Alternative models — if you need floats for pressure work or a built-in speed control, ask for the related kinetic theory models in the same enquiry.
- Delivery details — destination, delivery terms and any packing or tender requirements.
Frequently Asked Questions
What does the kinetic theory apparatus demonstrate?
The kinetic theory of gases — molecules in constant random motion — and related effects such as the thinning of air with increasing altitude, using metal spheres agitated by a motor.
How does it show air thinning with altitude?
When the spheres are agitated, more of them stay near the bottom of the tube and fewer reach the top, just as air is denser near the ground and thinner higher up.
How is the motor powered?
It is a DC motor fed through socket terminals on the apparatus. The supply voltage and current are not given in this listing, so ask JLab to confirm them with your quotation.
How many spheres are there, and how big is the tube?
The number and size of the spheres and the tube dimensions are not stated in this listing. JLab can confirm them on request.
How does it differ from the polystyrene-piston kinetic theory model?
Both use motor-driven balls. The polystyrene-piston model is listed with a 4–12 V DC motor, a transparent tube and floats for simulating pressure; this apparatus is the test-tube version with metal spheres.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and supplies it direct.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of physics demonstration apparatus and school lab equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The kinetic theory apparatus is built at JLab's own works rather than bought in from a trader, so schools, colleges, dealers and importers buy factory-direct, each unit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab ships worldwide to buyers in every region — Chad in Central Africa, Nepal in South Asia, Malta in Southern Europe, Norway in Northern Europe and Saudi Arabia in the Middle East, for example. See the JLab lab tenders page for tender supply.
