SIMPLE
RESPIROMETER
A complete unit for
comprising 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
thermo-barometer. CO2 given off by the respiring
organism is absorbed by potassium bydroxide in
the experimental chamber resulting in a change
in the level of liquid in the manometer tube.
Complete with wire baskets for supporting
organisms.
