Respirometer, Complete With Graduated And Levelling Tubes, Rubber Tubing And Stand

The Respirometer is a sophisticated laboratory apparatus engineered to measure and analyze the rate of respiration in germinating seeds, small invertebrates, or plant tissues by monitoring oxygen consumption and carbon dioxide evolution. Fabricated from premium borosilicate glass, this comprehensive system allows researchers and educators to quantify metabolic activity under controlled experimental conditions.

This complete turn-key assembly features a precision-bore graduated tube for accurate volume tracking, a companion leveling tube to maintain atmospheric pressure equilibrium, high-grade flexible rubber tubing for leak-proof connectivity, and a robust support stand. The use of borosilicate glass ensures excellent thermal stability and chemical resistance when utilizing potassium hydroxide (KOH) or other CO2-absorbing solutions.
