Respirometer Manufacturer,Supplier and Exporter in India
Product Code : EL-LS-5086
Jlab Export is a leading Respirometer Manufacturer,and suppliers in India
Respirometer (code EL-LS-5086) is a glass apparatus for comparing the rates at which small organisms absorb or give off gases during respiration, used in senior-school, college and university biology labs. Two stoppered boiling tubes connect through three-way taps to the limbs of a U-shaped graduated manometer, one holding the organisms and the other acting 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 the Micro Respirometer?
| Item | Construction | Other details |
|---|---|---|
| This respirometer (EL-LS-5086) | Two stoppered boiling tubes, three-way taps and a U-shaped graduated manometer | Control thermo-barometer; supplied with wire basket and 1 mL syringe |
| Micro Respirometer | Mounted on a board, 400 x 150 mm | For oxygen uptake and/or carbon dioxide output; rod for fixing on a retort stand |
Choose this respirometer for a two-tube set-up with three-way taps and a U-shaped graduated manometer; the Micro Respirometer is a board-mounted unit that fixes to a retort stand.
What Is the Respirometer Used For?
Living organisms take in oxygen and give out carbon dioxide as they respire. In this apparatus the carbon dioxide is absorbed by potassium hydroxide, so the gas taken up by the organisms shows as a movement of the liquid in the graduated manometer, and the rate of movement lets students compare how fast different organisms respire, or the same organisms at different temperatures. The second tube contains no organisms and acts as a thermo-barometer: changes in temperature or air pressure affect both tubes, so comparing them reduces the effect of these changes on the reading. Respirometers are used in class 11 biology work on respiration and in college and university practicals in plant and animal physiology, with small organisms such as germinating seeds or small insects held in the wire basket.
What to Specify When Ordering
- Quantity — usually one respirometer per student group.
- Reagent — potassium hydroxide is a separate catalogue item that can be quoted on the same enquiry.
- Model — this two-tube respirometer or the board-mounted Micro Respirometer.
Frequently Asked Questions
What does this respirometer measure?
It compares the rates at which small organisms absorb or give off gases during respiration, read from the change in level of the liquid in a U-shaped graduated manometer.
How does the respirometer work?
Carbon dioxide given off by the respiring organisms is absorbed by potassium hydroxide in the experimental chamber, and this changes the level of the liquid in the manometer tube.
What is the second tube for?
It acts as a control thermo-barometer. Because it holds no organisms, it shows the effect of temperature and air pressure alone, which helps separate those effects from the respiration being measured.
What is the syringe used for?
The syringe on the organism tube alters the level of the liquid in the manometer while the apparatus is being set up.
What comes with the respirometer?
It is supplied complete with a wire basket for supporting the organisms and a 1 mL syringe.
How does it differ from the Micro Respirometer?
The Micro Respirometer is mounted on a 400 x 150 mm board with a rod for fixing on a retort stand. This model uses two stoppered boiling tubes with three-way taps, one of them acting as a control thermo-barometer.
What should an export enquiry include?
The quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling requirements and a tender reference if one applies.
Who manufactures this respirometer?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a biology lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The respirometer is made at JLab’s own works rather than bought from a trader, so schools, colleges, universities, dealers and importers buy it factory-direct, each unit is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Hong Kong in East Asia, Malta in Southern Europe, Mexico in North America, Zambia in East Africa and Namibia in Southern Africa. Tender buyers can refer to the JLab lab tenders page.
