J TUBE, SCREW FITTING (LI8034)
Glass J tube formed from 1mm bore thick walled capillary tube, with a brass screw and collar at the end of the longer limb. Used for sampling small quantities of gas held over water (e.g. in photosynthesis or respiration experiments). A bubble of gas is introduced into the short limb. This is then lowered into reagent solution and the bubble moved back and forth so that reagent diffuses through the end water seal. The change in length of the bubble indicates the amount of gas taken up by the reagent. Use potassium, hydroxide for C02 or alkaline pyrogallol for 02. Dimensions long limb 250mm, short limb 100mm.

SIMPLE RESPIROMETER (LI8037)
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 hydroxide in the experimental chamber resulting in a change in the level of liquid in the manometer tube. Complete with wire baskets for supporting organisms.
