Product Description

The Bluelab pH Probe KCl Storage Solution is a potassium chloride (KCl) based storage and hydration fluid designed specifically for pH probes and pH pens. It helps keep the pH probe’s glass sensor moist and in optimal working condition when the probe is not in use. Proper storage in this solution improves response time, maintains accuracy, and extends the life of the pH probe by preventing drying of the internal reference electrolyte.

This version, STSOL120BL, is typically supplied as a carton/pack of six 120 ml bottles, ideal for regular use or multi-probe environments.

Key Features & Benefits

 Maintains Probe Performance: Keeps the glass sensor and internal reference electrolyte hydrated, which ensures quicker and more stable pH readings.
 Prevents Drying Out: Storing the probe dry or in plain water can reduce accuracy and shorten probe life; this solution prevents that by maintaining proper moisture levels.
 Extends Probe Life: Regular use of the correct storage solution helps prolong the usable life of pH probes and pens.
 Suitable for Regular Use: Ideal for growers, labs, aquariums, hydroponics, and other applications where pH probes are used frequently.

 Typical Use

1. After measuring pH, rinse the pH probe gently with clean water.

2. Fill the probe’s storage cap or a small container with KCl storage solution.

3. Place the probe tip into the solution so the glass sensor is submerged.

4. Store the probe upright in the solution when not in use.

5. Hydrate regularly, especially if the probe tip has dried out or hasn’t been stored in KCl before.

Storage & Handling

• Keep the bottle tightly closed when not in use to prevent evaporation.

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

• Do not use distilled or pure water for storage instead of this solution, as it can harm the probe’s internal chemistry.

• Change the solution if it becomes contaminated or cloudy.
