How should the pH meter electrode (acidity meter electrode) be stored for a long life
How should the pH meter electrode (pH meter electrode) be stored for a long life? Please store the pH meter electrode in 3mol/L potassium chloride solution (3M KCl) when not in use; it can be stored in pH7.00 buffer solution for a short time. Drying or immersing the pH meter (acidity meter) electrode in distilled water for a long time will shorten the service life of the electrode.
Maintenance problem: How to maintain the ph electrode (pH meter electrode). After using the ph meter (pH meter) electrode for a period of time, if you find that the slope becomes lower and the response speed becomes slower, you can try the following methods.
1. If the measured sample contains protein, use pepsin/hydrochloric acid washing solution (ME51340068) to clean the electrode membrane.
2. If the measured sample is oily/organic liquid, it can be washed with acetone or ethanol.
3. If the junction of the pH meter (acidity meter) electrode is found to be dirty and black, use mercaptan cleaning solution (ME51340070) to clean the junction.
4. Activate the electrode membrane. Activation method: soak in pH meter (acidity meter) electrode regeneration solution (ME51340073) for 30 seconds, then soak in 3mol/L KCl solution for 5 hours
