title: Influence of sterilization and temperature changes on the in vitro characteristics of the pH electrode.
abstract: 1. When chemical sterilization (with Korsolin, Cidex) is performed, a minimal duration of sterilization of 3 h is required for asepsis. 2. Duration of Korsolin sterilization up to 3 h does not influence the in vitro characteristics of the pH-electrode. 3. Sterilization with formaldehyde (24 h, 40 degrees C) is safe, but needs another 24 h restabilization time of the electrode. 4. The temperature dependence of the pH-electrode is minimal. With increasing temperature a slight decrease of pH measurement can be found (-0.02 pH units from 20--40 degrees C).
