A single bottle aerobic respirometer for the laboratory measurement of oxygen consumption rate and derived parameters in aerobic cultures.
This open system, allowing additions of test substances or nutrients throughout the testing period, unlike those respirometers based on pressure reduction techniques. It also supplies air to the culture, hence never being oxygen limiting like some simpler barometric systems.
The measurement principal is that of DO concentration measurement over time. Temperature stability is achieved with a self contained peltier heating/cooling system.
Three modes of operation are available:
