GroLine Electrode Storage Solution (500 mL) - HI70300-50 Alexapure Pro spigot Waterproof Design: IP67-rated protection allowsHI70300 050 is a GroLine storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. It is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated. Ideally a storage solution should be used; never store an electrode in distilled or deionized water. The GroLine storage solution is specifically formulated to minimize
