Product Description

The Bluelab pH Probe KCl Storage Solution 250 ml is a specialized potassium chloride (KCl) storage fluid designed to keep pH probes and pH pens properly hydrated when not in use. pH probes are delicate glass-ended instruments that can lose accuracy and lifespan if allowed to dry out. This storage solution helps maintain the internal reference electrolyte in the probe’s glass sensor, ensuring stable readings, quick response time, and longer probe life.

This version is often supplied as a pack/carton containing multiple 250 ml bottles — convenient for frequent calibration or multiple probes.

Key Features & Benefits

 Maintains Probe Performance: Keeps the glass sensor and internal reference electrolyte moist for stable and accurate measurements.
 Prevents Drying: Dry probes can degrade quickly and give unstable readings — this solution prevents that.
 Extends Probe Life: Regular storage in the correct KCl solution helps extend the useful life of pH probes and pens.
 Easy to Use: Simply fill the probe cap or a small container with solution for storage between measurements.

Typical Use

1. After taking a pH measurement, rinse the probe gently with clean water.

2. Fill the probe’s storage cap or a small container with the KCl solution so the glass tip remains submerged.

3. Store the probe upright in the solution until its next use.

4. Hydrate regularly, especially if the probe has been dry or under-used.

5. If the probe has dried out, soaking it in KCl solution before calibrating can help restore performance.

Storage & Handling

• Keep the bottle tightly sealed when not in use to prevent evaporation or contamination.

• Store in a cool, dry place out of direct sunlight.

• Do not substitute plain water for proper storage, as water can damage the internal reference and shorten the life of the probe.
