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. * Supplied complete with wire baskets for supporting organisms * Manufacturer's part BI0218 https://elecena.pl/product/27243865/eisco-respirometer-simple-kit 2024-11-12 https://elecena.pl/product/27243865/eisco-respirometer-simple-kit 2025-05-25
