Lung Demonstration Model Manufacturer,Supplier and Exporter in India
Product Code : EL-HBE-6965
Jlab Export is a leading Lung Demonstration Model Manufacturer,and suppliers in India
Lung Demonstration Model (code EL-HBE-6965) is a working model of breathing in which two sacs stand for the lungs, a rubber membrane acts as the diaphragm and a clear plastic enclosure represents the chest cavity. Moving the membrane makes the sacs fill with air and empty again, so students get a firsthand view of how the lungs work. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Lung Demonstration Models?
| Model | Construction as listed | Listed size |
|---|---|---|
| This model (EL-HBE-6965) | Two sacs as lungs, rubber membrane diaphragm, clear plastic enclosure as the chest cavity | 6.5 in D x 5 in H |
| Lung Demonstration Model (bell jar) | Two rubber balloons, rubber stopper and bell jar, with a thin rubber diaphragm at the bottom of the jar | 17 x 17 x 20 cm |
Choose this model for a compact clear plastic demonstrator built exactly as described above. The bell-jar version is listed with a rubber stopper and a larger footprint; if the enclosure material matters for your order, ask JLab to confirm it for either model.
What Is the Lung Demonstration Model Used For?
The model shows the mechanism of breathing that NCERT introduces in class 7 science under respiration in organisms and builds on in the life processes chapter of class 10 and breathing and exchange of gases in class 11 biology. Pulling the rubber membrane down imitates the diaphragm contracting and flattening: the space inside the enclosure grows, the pressure around the sacs falls and air flows in to inflate them, as in inhalation. Letting the membrane return, as the diaphragm relaxes, shrinks the space and the sacs empty, as in exhalation. Students see that air moves because of pressure changes created by the diaphragm rather than because the lungs draw it in by themselves.
Teachers often follow the demonstration by asking what the model leaves out: a real chest wall is not rigid, and the rib cage moves up and out with the intercostal muscles, which makes a good discussion point for older classes. Handle the rubber membrane gently, avoid over-stretching it and keep the model away from sharp objects and strong heat so the rubber parts last.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; schools usually plan one per demonstration bench or student group.
- Model choice — this clear plastic model or the bell-jar version compared above.
- Spare rubber parts — ask whether replacement sacs or diaphragm membranes can be added to the quotation.
- Companion items — a lung chart, a lung volume kit or a spirometer for follow-up practicals.
Frequently Asked Questions
How does the lung demonstration model work?
Pulling the rubber membrane down enlarges the enclosure and the two sacs fill with air; letting it go back empties them. These are the same pressure changes that move air in and out of the lungs when the diaphragm contracts and relaxes.
What size is the model?
It is listed as 6.5 in diameter x 5 in high, about 16.5 x 12.7 cm. Confirm the dimensions with JLab if they matter for storage or a tender.
How does it differ from the bell-jar lung demonstration model?
This one uses two sacs, a rubber membrane and a clear plastic enclosure. The other is listed with two rubber balloons, a rubber stopper, a bell jar and a thin rubber diaphragm, at 17 x 17 x 20 cm.
Does the model show how the ribs move?
No. It models the diaphragm only, so rib and intercostal muscle movement is better explained with a chart or torso model beside it.
Who manufactures this lung model?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of science teaching models and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This lung model is assembled at JLab’s own works and is not bought in from a trader, so schools, colleges, dealers and importers order it factory-direct, every model is checked by eye before packing, and repeat orders and spare parts are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Hungary in Eastern Europe, Kyrgyzstan in Central Asia, Ethiopia in East Africa, Ecuador in South America and Laos in Southeast Asia. Tender buyers can find details on the JLab lab tenders page.
