Electrode storage solution, 500 mL bottle
  • Top of Form

    HI70300L is a storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. 

    Properly storing your pH electrode in a solution keeps the glass membrane well hydrated which maintains proper function and provides accurate readings.

    ·       Special formulation to minimize microbial growth and osmotic/diffusion effects between the solution and inner reference electrolyte 

    ·       Clearly marked expiration date and lot number for traceability. 

    ·       Designed for storing any pH or ORP electrode. 

    Bottom of Form


    HI70300L is a pH storage solution that can be used to store your pH electrode*. To ensure an optimum response time, the glass sensor tip and the reference junction of the pH electrode should be kept moist and not be allowed to dry out 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 a suitable way to store the electrode. The HI70300L should also be used to rehydrate the electrode after a cleaning procedure by soaking for at least one hour before taking measurements.


    * Never store pH or ORP electrodes in distilled or deionized water. Doing so will shorten the life of the sensor.
