pH Storage Solution

Before First Use

Rinse the pH electrode with deionised or distilled water to remove any residual contaminants. If the electrode has dried out, hydrate it by immersing the glass bulb and junction in storage solution for at least one hour before taking measurements. Overnight hydration is preferable for maximum performance.

During Routine Use

After each measurement session, rinse the electrode thoroughly with deionised or distilled water. Gently shake off excess water without wiping the glass bulb to avoid static or damage.

Storage Between Uses

Ensure the sensing glass and reference junction remain moist when the electrode is not in use. Replace the solution in the protective cap with a small amount of storage solution so that the electrode tip and junction are covered. Never store electrodes dry or in plain distilled/deionised water, as this can cause the junction to dry out and degrade performance.

After Cleaning

If the electrode has been cleaned with a dedicated cleaning solution to remove deposits, always rinse with deionised or distilled water and then soak the electrode in storage solution for at least one hour before use.

Extended Periods of Non-Use

For extended storage, check periodically that the storage solution in the protective cap remains sufficient to keep the junction and glass bulb moist. Replenish with fresh storage solution if evaporation occurs.
