Hanna HI70300-023 GroLine Electrode Storage Solution (230 mL) hydro-filter so nutrients are more likelyHI70300 023 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 Hanna Instruments storage solution is specifically formulated to
