PH CONTROL IN MICROBIOLOGICAL RESEARCH TECHNIQUE

Abstract

A sterilizable pH measuring chain was developed in which the glass and the reference electrode (single-bar or single-member measuring chain) were housed together in a compact frame or mounting and in which the overpressure can very easily be compensated for. The shock-resistant electrodes reveal good properties with respect to absence of hysteresis, stability of transconductance, and the position of the zero-point even after heat stress, so that the electrodes can be sterilized along with the rest in the fermenter. In this way the microbiological breeding systems will be kept sterile. The article also includes the set up for a control loop for automatic pH control.
