Reagecon pH Electrode Storage Solution is a specially formulated and buffered solution containing 3M Potassium Chloride (KCl), with a special preservative, designed to optimise functionality, accuracy, responsiveness and life span of a pH electrode. Every pH electrode must be stored in such a solution, between readings or when not in use. - A pH electrode is an extremely sensitive device and almost all pH errors are as a result of an electrode fault. Although the fault or failure may be predominantly due to the reference half cell, the sensing half cell must also be maintained correctly.
