Steam sterilizable probes for dissolved oxygen measurement. Reprinted from Biotechnology and Bioengineering, Vol. VI, Issue 4, Pages 457-468 (1964).

Steam-sterilizable membrane probes for monitoring the dissolved oxygen level in fermentors, or the oxygen content of gas streams, are described. The probes have a silver cathode, a lead anode, and an acetate buffer as an electrolyte. The membrane is Teflon. The current output of the probes in the absence of oxygen is negligible.
