A ph electrode is active and stable only after wetting.
Ph electrode storage solution kcl.
The correct storage of the ph electrode can increase its lifetime significantly.
Enhance the performance and extend the life of electrodes.
Firstly you should make sure you always keep your ph electrode moist the best solution to submerge the probe for long and short term storage is 4m potassium chloride solution kcl.
Use electrode storage solutions with ph and reference electrodes to maintain proper functioning and accurate readings.
Do not store electrode in distilled or deionized water this will cause ions to leach out of the glass bulb and render your electrode useless.
Always keep your ph electrode moist.
Potassium chloride electrolyte standard solution 3m chem lab is a filling solution for ph electrodes containing 224g kcl per liter of water.
The substances can reestablish proper working conditions after cleaning procedures or when the electrode has not been in use for an extended time period.
For electrodes filled with potassium chloride c kcl 3 mol l as reference electrolyte we have developed a dedicated storage solution which keeps the glass membrane in top quality without impairing the performance of the diaphragm.
We recommend that you store your electrode in a solution of 4 m kcl.
If you re out of storage solution ph 4 or 7 buffers can be used in a pinch.
If 4 m kcl is not available use a ph 4 or 7 buffer solution.
It is used for proper electrode storage to maintain optimal electrode performance.
