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 suits senior-school biology and college botany and zoology practicals. For schools, colleges, tender contractors and distributors, the set is quoted and packed for dispatch by Science Lab Supplies in Ambala, India.

Specifications

Every component of the two-chamber respirometer has its own row in the table. In short, two respiration tubes are closed with corks and fitted with three-way taps, extensions from both lead to a graduated manometer, and a stand holds everything upright; chamber volume, materials and manometer range 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, introduced with the Stages of Seed Germination Chart.
• B.Sc. botany practicals: comparing respiration of different seeds or at different temperatures, checked on Laboratory Thermometers.
• Zoology and general biology: respiration of small invertebrates using a control chamber.
• Data handling: plotting manometer displacement against time, with intervals set on a 0–60 minute Mechanical Timer 60min.

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, a carbon dioxide absorbent, a water bath and timing equipment can be arranged by the laboratory or added to the quotation.

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 so the whole plant-physiology bench is covered by one school biology lab equipment order.

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. Request a price by writing in on the contact page, build a respiration-practical list in the enquiry cart, or look over the lab tender page if a formal tender applies.

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 in the results.

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, operating out of Ambala in India, confirms the set's details, packing and dispatch on every quotation, whether it is for a school, a college department or a contractor.

Which carbon dioxide absorbent can be used?
Potassium hydroxide or soda lime can absorb the carbon dioxide, and either can be added to the quotation. Both are corrosive, so they should be prepared and handled by trained staff away from the specimen.
