Eisco Respirometer Simple Kit

This simple respirometer kit from Eisco consists of two stoppered boiling tubes connected by three-way taps leading to a graduated manometer. One tube holds the organisms and has a syringe for altering the level of liquid in the manometer during set-up. The other tube acts as a control thermo barometer.CO2 given off by the respiring organism is absorbed by potassium hydroxide in the experimental chamber resulting in a change in the level of liquid in the manometer tube.
