Respirometer with Stand

Product Code : SCL-LG-11978

Respirometer with Stand (SKU SCL-LG-11978) is a two-chamber apparatus for studying respiration: gas-pressure changes in two cork-closed tubes move the liquid in a graduated manometer, so students can compare respiring seeds or small organisms with a control. It is used in senior-school biology and in college botany and zoology practicals. Science Lab Supplies delivers it from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.

Specifications

Two respiration tubes are closed with corks and fitted with three-way taps, and extensions from both tubes lead to a graduated manometer. A stand holds the chambers and manometer upright for reading. Chamber volume, materials, manometer range and graduation interval are not stated in the listing and are confirmed on the quotation.

Applications and Experiments for the Respirometer with Stand

With a carbon dioxide absorbent in the chambers, oxygen taken up by respiring material lowers the pressure and moves the manometer liquid. Readings at equal intervals let students compare the experimental chamber with the control and see how temperature or seed type changes the rate of respiration.

• NCERT Class 11 biology (respiration in plants): oxygen uptake by germinating seeds.
• B.Sc. botany practicals: comparing respiration of different seeds or at different temperatures.
• Zoology and general biology: respiration of small invertebrates using a control chamber.
• Data handling: plotting manometer displacement against time.

Carbon dioxide absorbents such as potassium hydroxide or soda lime are corrosive: handle them under supervision and keep them out of contact with the specimen. Hold the temperature steady, since warming alone moves the manometer.

Standard Scope of Supply

The set comprises two respiration tubes, cork closures, three-way taps, connecting extensions, one graduated manometer and one supporting stand. Specimens, manometer fluid, carbon dioxide absorbent, a water bath and timing equipment are not confirmed as included.

Packing, MOQ and Lead Time

You can ask for one respirometer for demonstration or enough for each practical group, and the quotation lists packing, delivery time and price for that quantity. Fermentation tubes and potometers can be added for a full plant-physiology bench of laboratory glassware.

As a registered exporter with its own Importer-Exporter Code, Science Lab Supplies can ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. For prices, message us via the contact page, place items in the enquiry cart, or review the lab tender page for institutional tenders.

Frequently Asked Questions

Why does the respirometer have two chambers?
One tube holds the respiring specimen and the other acts as a control, so pressure changes not caused by respiration, such as small temperature shifts, can be allowed for.

Can it measure oxygen consumption?
It shows relative oxygen uptake when carbon dioxide is absorbed and conditions are controlled. Absolute values need the chamber volume and manometer calibration, which the quotation can confirm.

Who supplies the Respirometer with Stand?
Science Lab Supplies, based in Ambala, India, is the supplier; it confirms the set's details, packing and dispatch on every quotation for schools, colleges and contractors.

Is the carbon dioxide absorbent included?
No absorbent is listed with the set. Laboratories normally use potassium hydroxide or soda lime, both corrosive, prepared and handled by trained staff.
