Respirometer

When operating in the aerobic mode, oxygen – from a supply of pure oxygen – is added in small increments into each respirometer vessel in response to oxygen uptake and carbon dioxide absorption. This mode of operation maintains a constant oxygen concentration in the headspace within the reaction vessel. Oxygen transfer from the headspace to the liquid phase is accomplished by using ...
