摘要：
New sensitive membrane composition and glass preparation techniques have been found to make our GKF sterilizable pH glass electrode. The electrode has a 0 0.34 zeropotential pH shift after 54 continual cycles of sterilization at 121 degrees C (each cycle lasts 30 minutes). Before sterilization its zeropotential pH is 6.5 +/- 0.5. Its inner resistance is smaller than 500M Omega, its PTS is larger than 95% and its insulation resistance is larger than 10 ''Omega.
