Unlike conventional reference electrodes, there is no need to store Leak-Free electrodes in concentrated chloride solution.  However, if the electrode was left dry for a very long period of time, it should be immersed in water for a few hours to recover.

If you plan to use the electrode in solutions containing ions that form precipitates with chloride and potassium ions, such as silver and perchlorate ions, we DO NOT recommend storing the electrode in potassium chloride solution.  This may cause the adsorption of potassium and chloride ions at the electrode surface.

If you plan to use the electrode in dry organic solvent, the electrode should be washed with that solvent or acetone to remove water.  After the experiment, the electrode should be stored in aqueous solution NOT in the organic solvent.
