Hanna Solutions Storage Solution - 500 ML

Hanna Instruments GroLine electrode storage solution (HI70300-050) is an electrode storage solution for pH and orp electrodes, made to keep sensors ready between measurements. This probe care solution supports accurate readings by maintaining the condition of the pH glass membrane during storage.

As a dedicated pH electrode storage solution, it helps keep the pH glass membrane hydrated, which supports proper electrode function over time. That hydration focus matters for anyone relying on steady pH numbers, since a well-kept glass membrane is central to consistent response. For growers and water-testing users, it’s a practical electrode maintenance solution that fits easily into a regular meter-care routine without adding extra complexity.

This GroLine storage solution is prepared with reagent grade chemicals, supporting consistent quality for day-to-day electrode care. It’s designed for both pH and orp electrode storage, making it a straightforward choice when one solution needs to cover multiple probe types used in the same testing kit. Keeping a dedicated storage solution on hand also helps simplify how equipment is kept between checks, especially in busy greenhouse and hydroponics environments where handheld meters see frequent use.

Another key benefit is that it helps to minimize clogging of pH and orp junctions, which supports stable readings and reduces performance issues that can develop with routine exposure to real-world samples. That “minimize junction clogging” focus makes it especially useful for users who test often and want their probe to stay responsive, since a clean, functioning junction is essential for dependable performance.

This Hanna Instruments storage solution is a good fit for anyone maintaining pH meters and orp meters who wants a dedicated electrode storage solution that supports hydration of the pH glass membrane, helps minimize junction clogging, and is built around reagent grade chemicals for reliable probe care.
