Simple Respirometer, 7 Inch - Used To Measure Oxygen Absorption & Metabolism

MEASURES OXYGEN ABSORPTION || Useful for measuring the rate at which some respiring plant or animal material absorbs oxygen, measuring rate of metabolism INCLUDED || Two respirometer vessels, two connecting tubes, manometer U-tube and a single-use syringe GREAT PRACTICE TOOL || Excellent practice and experimentation tool for students, teacher or even at home. LARGE || Apparatus is approximately 7" tall - Each vessel is approximately 1" in diameter - Stand is approximately 4.75" tall, 8.5" wide and 4.5" long EASY TO USE || One tube holds the organisms and has syringe for altering the level of liquid in the manometer - The other tube acts as a control thermo barometer     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. Comprising rates of absorption or evolution of gases by small organisms, during respiration. The apparatus consists of two stoppered boiling tub
