Respirometer Manufacturer,Supplier and Exporter in India
Product Code : EL-AE-6714
Jlab Export is a leading Respirometer Manufacturer,and suppliers in India
Respirometer (code EL-AE-6714) is a compact unit for comparing the rates at which small organisms absorb or give off gases during respiration. Two stoppered boiling tubes connect through three-way taps to the two limbs of a graduated manometer: one tube holds the organisms and has a syringe for setting the liquid level, the other acts as a control thermo-barometer. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Respirometers?
| Model | Design as listed | Other listed details |
|---|---|---|
| This respirometer (EL-AE-6714) | Two stoppered boiling tubes, three-way taps, graduated manometer; control tube as thermo-barometer | Syringe on the organism tube; carbon dioxide absorbed by potassium hydroxide |
| Respirometer | Two stoppered glass boiling tubes, three-way taps, U-shaped graduated manometer; control thermo-barometer | Supplied complete with a wire basket for supporting organisms and a syringe |
| Micro Respirometer | Board-mounted unit for studying gas exchange during respiration | Measures oxygen uptake and/or carbon dioxide evolved; rod for fixing on a retort stand |
The two respirometers are described in almost the same terms; the other listing names a wire basket for holding the organisms, which this one does not mention, so ask JLab to confirm the fittings if a basket matters to you. Choose the micro respirometer if you want a board-mounted unit held on a retort stand.
What Is the Respirometer Used For?
Students place germinating seeds, woodlice or maggots in the experimental tube, with potassium hydroxide to absorb the carbon dioxide they release, and watch the manometer: as the organisms take up oxygen, the gas volume falls and the liquid moves. Because the control tube is a thermo-barometer, changes caused by room temperature or air pressure affect both limbs and cancel out, so the reading reflects respiration. Timing the movement gives a rate that can be compared between organisms, or between the same seeds at different temperatures. It suits the rate-of-respiration practical in class 11 biology and plant and animal physiology work in college labs. Handle potassium hydroxide with eye protection and gloves, keep it separated from the organisms, and use the syringe to reset the liquid level between runs.
What to Specify When Ordering
- Quantity — the minimum order is 10 units, for example one per student group.
- Fittings — confirm whether you need a support for the organisms in the experimental tube.
- Reagents — potassium hydroxide is not listed as part of the unit; ask if you want it quoted separately.
Frequently Asked Questions
What does the respirometer measure?
It compares rates of gas absorption or evolution by small organisms during respiration, shown as a change in the level of liquid in a graduated manometer.
Why are there two tubes?
One tube holds the organisms; the other is a control thermo-barometer, so temperature and pressure changes affect both sides and do not distort the reading.
What is the potassium hydroxide for?
It absorbs the carbon dioxide given off by the respiring organisms in the experimental chamber, which is what produces the change in the manometer level.
What is the syringe for?
It alters the level of liquid in the manometer during set-up, so the scale can be zeroed before timing starts.
Who manufactures this respirometer?
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 laboratory apparatus manufacturer in India for biology and other sciences, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This respirometer is assembled in JLab’s own works instead of being sourced from a trader, so institutions, dealers and importers deal directly with the maker, each unit is visually inspected before dispatch, and repeat orders and spares are handled by the same team. JLab exports worldwide and ships to buyers in every region — for example Serbia in Southern Europe, Libya in North Africa, the USA in North America, Gabon in Central Africa and Mongolia in East Asia. Tender information is on the JLab lab tenders page.
