The Metabolism Chamber is a 250-mL sample bottle with 2 holes cut specifically to allow PASCO gas sensors to simultaneously measure carbon dioxide and oxygen gas concentrations.

One of the most popular methods to explore cellular respiration in the biology lab is to measure the production of carbon dioxide by germinating seeds using a carbon dioxide sensor. The study of cellular respiration becomes richer when students simultaneously obtain carbon dioxide gas data and oxygen gas data.
