YSI 53 Biological Oxygen Monitor

The YSI 53 Biological Oxygen Monitor is a device for measuring oxygen uptake or evolution by biological systems. It produces “Warburg” type oxygen evolution or uptake curves in 5 to 20 minutes.

The heart of the system is the YSI 5331 Oxygen Probe. This probe is a specially designed Clark type polarographic electrode.

The total system consists of the Model 53 Electronic Unit, the Model 5301 Standard Bath Assembly, two 5331 Oxygen Probes, one 5775 Probe Service Kit, and the 5350 Membrane Applicator Kit. A Constant Temperature Circulator supplied by the customer is also required.
