Aqua Master Tools KCl Storage Solution - 100 ml

Product detailed description

Aqua Master Tools KCl 3 mol/l storage solution is intended for pH electrodes that should be stored in storage liquid between measurements. It helps keep the glass membrane and reference electrolyte in good condition, so the probe does not dry out unnecessarily.

When to use KCl

Use the solution for routine and longer-term storage of pH probes for which storage in liquid is suitable. For Aqua Master Tools pH pens with a dry electrode, follow the specific instructions for the relevant model.

How to store the probe in KCl

Pour a little storage solution into the electrode's protective cap and place the probe in it. This is exactly what KCl is intended for: a bath between measurements in which the glass membrane and reference electrolyte remain in good condition. A glass pH electrode should not be stored dry or in distilled water – this is why it is stored in KCl, not in a cup of water.

Rinse the electrode thoroughly with clean water before storage and before the next measurement, so that fertiliser residue is not introduced into the cap. Close the bottle immediately after pouring and keep it at a temperature between 15 and 25 °C. Do not return solution in which the probe has already been standing to the bottle – pour it away and use fresh solution next time.

Specifications

If the probe is heavily contaminated, first use Aqua Master Tools Cleaner D cleaning solution, rinse the probe and only then store it in KCl.

Frequently asked question

Is KCl a calibration solution?

No. KCl is used for storing pH electrodes. To calibrate a pH metre, use pH 4 and pH 7 solutions.
