Electrode preservation and cleaning solutions are special solutions for the maintenance and maintenance of pH electrodes. Electrode preservation solutions are used to store electrodes for long periods of time to maintain their performance and extend their lifespan, and are usually the solutions recommended by the electrode's manufacturer. The cleaning solution is used to remove dirt and sediment from the electrode surface to ensure accurate and stable measurements. The cleaning solution should be selected according to the material and usage of the electrode to avoid damage to the electrode.
HI70300L pH Electrode Storage Solution (500 mL) is an electrode storage solution formulated with reagent-grade chemicals to maintain optimal performance of pH and ORP electrodes. The stock solution is specially formulated to minimize bacterial growth on the electrodes and keep the glass membrane moist to ensure proper electrode function and accurate reading. The storage bottles are labeled with expiration dates and lot numbers and are equipped with tamper-evident seals to ensure the quality and freshness of the solution. HI70300L can also be used to rehydrate the electrode after cleaning, soaking for at least one hour before taking measurements. In order to guarantee the response time of the electrode, it is recommended to keep the electrode in a small glass vial with a storage solution or to replace the solution in the protective cap. This stock is valid for up to 5 years when unopened. Please note that pH or ORP electrodes should never be stored in distilled or deionized water to avoid shortening the lifetime of the sensor.
