Biological Respirometer with Stand

Quick answer: A biological respirometer with stand is used to measure the rate of respiration of a living organism, such as germinating seeds or small invertebrates, by tracking the volume of oxygen consumed over a fixed time period.
The organism is sealed inside a chamber together with a chemical, such as potassium hydroxide, that absorbs the carbon dioxide it produces. Since the carbon dioxide is removed from the system, any change in gas volume inside the chamber reflects the oxygen being consumed by the organism. This volume change is read from a graduated liquid manometer connected to the chamber, giving a simple, quantitative measure of respiration rate.
The accompanying stand holds the chamber and manometer securely at a stable, consistent level throughout the experiment, which is important for taking accurate, repeatable readings in a school or college biology practical.

Frequently Asked Questions
What is a biological respirometer used for?
It is used to measure the rate of respiration of a living organism, such as germinating seeds or small invertebrates, by tracking the volume of oxygen consumed over time.
How does the respirometer measure respiration rate?
Carbon dioxide produced by the organism is absorbed by a chemical such as potassium hydroxide, so any change in gas volume inside the sealed chamber reflects oxygen consumption, which is read from a graduated liquid manometer.
What does the stand do?
The stand holds the respirometer chamber and manometer securely and at a consistent level, keeping readings stable and easy to take throughout the experiment.
What organisms can be studied with this apparatus?
Common subjects include germinating seeds, small invertebrates and other small living specimens used in respiration rate experiments in school and college biology.
Can temperature affect the results?
Yes, respiration rate is temperature-dependent, so experiments are usually carried out at a controlled, known temperature for comparable results.
Does LabEquip supply respirometers for bulk or institutional orders?
Yes. LabEquip supplies biological respirometers with stand to schools, colleges and laboratories across India, including bulk and institutional orders. Contact us for a quotation.
