GroLine Electrode Storage Solution (120 mL)

The HI70300-012 is specially formulated to preserve the performance of pH and ORP electrodes. This storage solution maintains the hydration of the glass membrane and keeps the reference junction clear—critical for ensuring fast, reliable measurements. Unlike plain water, it prevents microbial growth and osmotic imbalances that could compromise sensor function. It's also ideal for rehydrating electrodes after cleaning: simply soak for at least one hour to guarantee optimal response time.

The solution comes in an airtight, tamper-proof bottle, with clearly labeled lot and expiration dates for traceability. Unopened, its shelf life extends up to five years, making it a dependable choice for long-term electrode maintenance.
