About This Product
Organisms are placed in one tube, where potassium hydroxide absorbs the CO2 they give off, so the liquid level in the manometer changes as respiration goes on. The other tube serves as a thermo-barometer control, and the syringe on the experimental side is used to set the liquid level before readings start.
Frequently Asked Questions
How does the Respirometer show respiration?
CO2 given off by the organisms is absorbed by potassium hydroxide in the experimental chamber, which changes the level of liquid in the manometer tube.
What is the second tube for?
It acts as a control thermo-barometer, while the first tube holds the organisms and has a syringe for adjusting the manometer liquid level during setting up.
