For the quick response of the pH electrode throughout the measurement of sample pH, the electrode needs to be soaked into a little acidic solution and rinse with distilled water. The pH electrode should always be stored in a moist state when you keep it for a long time and between regular measurements and you can dip the pH electrode in pH 4.00 buffer solution or saturated or 3M KCL solution.
Never store the electrodes in de-ionized or distilled water, since this is the migration of the filled solution (3 M KCL) of the electrode, thus reduces the response of the hydrogen ion.
Electrode storage:
Storage between the measurements
The electrode should be left in the lab environment, Do not store in the distilled water.
Short-term storage
Immerse the pH electrode tip in electrode storage solution (3 M KCL/Saturated KCL/ pH 04.00 Buffer solution). Do not allow a solution to evaporation and crystallization on the electrode.
Long-term storage
Electrode tip covers with safety cap.
