If a combined pH glass electrode is kept in this medium then the performance of the glass membrane does not change with respect to the response time and the alkali error
Normally a combined pH glass electrode is only stored in c(KCl)=3mol/l because it is then immediately ready for use without prior conditioning of the diaphragm.
However, long-term storage in KCl damages the glass membrane and causes increased response times.
For the pH glass membrane the optimal storage medium would be distilled water, but after such storage the diaphragm would have to be conditioned for several hours.
The new 6.2323.000 storage medium (patent pending) has been developed to solve this very problem.
If a combined pH glass electrode is kept in this medium then the performance of the glass membrane does not change with respect to the response time and the alkali error.
If c(KCl)=3mol/l is additionally used as the reference electrolyte then the optimised composition of the storage medium guarantees that the pH glass electrode is always ready for immediate use.
Conditioning prior to the measurement is not necessary, no matter how long the electrode has been stored.
