* Specially formulated storage solution for aquarium pH and aquarium ORP electrodes * Keeps aquarium electrode sensor tip and reference junction moist when not in use * Prepared with reagent-grade chemicals to ensure optimum aquarium electrode performance Extend sensor life of your aquarium electrode by properly storing it when not in use. Hanna Electrode Storage Solution is a specially formulated electrode storage solution prepared with reagent-grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. Proper storage of your aquarium electrode in Hanna Electrode Storage Solution keeps the glass membrane well hydrated which in turn helps maintain proper electrode function and accurate readings. Use the Hanna Electrode Storage Solution to store your aquarium electrode or to rehydrate your electrode after cleaning by soaking for at least one hour before taking measurements. Air tight bottle with a tamper-proof seal ensures quality and freshness of solution. Special formulation minimizes bacterial growth on your electrode. Each 230mL bottle is marked with a lot number and expiration date and has an expiration of 5 years from manufacture for an unopened bottle. Did You Know? To ensure the best response time, the sensor tip and the reference junction of your pH or ORP electrode should be kept moist when not in use. Placing the pH electrode in a small glass filled with storage solution or replacing the solution in the protective cap is an easy way to store your electrode. Never store pH or ORP electrodes in distilled or deionized water. Doing so will shorten the life of the sensor.
