Respirometer

Product Code : EL-BL-10824

Quick Answer: The Respirometer is a compact unit for comparing rates of gas absorption or evolution by small organisms during respiration, using two stoppered boiling tubes linked to a graduated manometer.

Last updated: October 2026

Key Features

  • Two stoppered boiling tubes connected by three-way taps to either limb of a graduated manometer
  • Experimental tube with a syringe for setting the manometer liquid level
  • Second tube acts as a control thermo-barometer
  • Potassium hydroxide absorbs the carbon dioxide given off
  • Wire baskets for supporting the organisms

About This Product

One boiling tube holds the organisms on a wire basket, while the other serves as a control thermo-barometer. Carbon dioxide given off by the respiring organisms is absorbed by potassium hydroxide in the experimental chamber, and the result shows as a change in the liquid level of the manometer tube. A syringe on the experimental tube is used to adjust that level during set up.

Frequently Asked Questions

How does the Respirometer show respiration?

Carbon dioxide from the organisms is absorbed by potassium hydroxide, which changes the liquid level in the graduated manometer.

What is the second tube for?

It acts as a control thermo-barometer.
