HI-9072 is a 13 mL electrode storage solution supplied in a dropper bottle, designed to help maintain the performance and longevity of pH and ORP electrodes.

Regular storage in Hanna Storage Solution helps keep the sensor tip and reference junction from drying out, while also reducing bacterial growth during periods of non-use. This supports faster response times and more stable, accurate readings.

Formulated with reagent grade chemicals, HI-9072 is designed to help ensure consistent electrode performance in both pH and ORP measurements.

After cleaning the electrode with a suitable cleaning solution, it should be rinsed with tap water and then placed in the storage solution before use or storage. Between measurements, it helps limit microbial growth and reduces issues caused by diffusion and osmosis while keeping the sensing elements properly hydrated.

Each bottle is sealed in an air-tight, tamper-proof container to maintain solution quality and freshness, and includes a batch number and expiry date for traceability.
