School Lab Respirometer

School Lab Respirometer

One tube holds the organisms and has a syringe for altering the level of liquid in the manometer during set up.  
A compact unit for comparing rates of absorption or evolution of gases by small organisms during respiration.  
The other tube acts as a control thermo-barometer.  
C02 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.  
The apparatus consists of two stoppered boiling tubes connected by three way taps to either limb of a graduated manometer.  

Specification: 
The apparatus consists of two stoppered boiling tube connected by three-way taps to either limb of graduated manometer.  
Complete with wire baskets for supporting organisms.
