pH electrode storage

Metrohm’s storage solution guarantees that your pH glass electrode is always ready for immediate use.

The Metrohm storage solution, gentler than 3 mol/L KCl

Long-term storage in KCl damages the glass and results in ever-increasing response times.

When a combined pH glass electrode is kept in this Storage Solution the performance of the glass membrane does not change regarding response time and the alkali error.

If c(KCl) = 3 mol/L is additionally used as the reference electrolyte the optimised composition of the Storage Solution guarantees that the pH glass electrode is always ready for immediate use.

Conditioning before the measurement is not necessary, no matter how long the electrode has been stored.
