Hanna Instruments GroLine Storage Solution, 500mL Molds & Parts and VPD triggers but alsoThe GroLine storage solution is 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 microbial growth
