Popis: New sensitive membrane composition and glass preparation techniques have been found to make our GKF sterilizable pH glass electrode. The electrode has a 0.34 zeropotential pH shift after 54 continual cycles of sterilization at 121 o C (each cycle lasts 30 minutes). Before sterilization its zeropotential pH is 6.5±0.5. Its inner resistance is smaller than 500MΩ, its PTS is larger than 95% and its insulation resistance is larger than 10''Ω
