GroLine Electrode Storage Solution (230 mL)

The HI70300-023 is a storage solution specially formulated to maintain the optimal condition of pH and ORP electrodes. It ensures that the glass membrane remains hydrated and the reference junction stays clear, which is vital for fast, accurate measurements. Unlike distilled or deionized water—which can harm electrodes—this solution prevents microbial growth and minimizes osmotic effects from the internal reference electrolyte.

Packaged in an airtight, tamper-proof bottle, the solution includes clear labeling with a lot number and expiration date. Unopened, it remains effective for up to five years, making it ideal for consistent long-term storage and maintenance.
