Product Description

For comparing rates of absorption or evolution of gases by small organisms, during respiration. The apparatus consists of two stoppered boiling tubes connected by three-way taps to either limb of a graduated manometer.

One tube holds the organisms and has a syringe for altering the level of liquid in the manometer during setting up.

The other tube acts as a control thermobarometer. CO2 given off by the respiring organisms is absorbed by potassium hydroxide in the experimental chamber resulting in a change in the level of liquid in the manometer tube.

Complete with instructions and wire baskets for supporting organisms.
