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.

What is pH Electrode Storage Solution? pH Electrode Storage Solution is a specially formulated liquid designed for the correct storage and maintenance of pH electrodes. It helps preserve electrode sensitivity, prevents dehydration of the sensing glass and junction, and supports consistent, reliable measurements without the need for pre-soaking before use.

Manufactured in our UK Facility: Our pH Electrode Storage Solution is manufactured and packaged using non-toxic, chemical-resistant containers, ensuring reliable quality for our customers.

Frequent Uses

pH Electrode Storage
Used for both short-term and long-term storage of pH electrodes to maintain hydration of the sensing element and ensure measurement accuracy.

Electrode Performance Maintenance
Helps maximise electrode lifespan and performance by preventing drying out and reducing the risk of junction blockage.

Refill Solution for pH Probes
Suitable for use as a refill solution in compatible refillable pH electrodes, supporting stable reference conditions.

Laboratory and Industrial Use
Commonly used in laboratories, education, water testing, and general analytical environments where pH electrodes are routinely stored between measurements.
