## Description

The 'LEAK FREE' reference electrodes were developed to eliminate the problems associated with the use of conventional porous junction-based reference electrodes such as clogging, sample contamination, electrolyte loss, changing of ionic strength of the sample, and the difficulties with organic based solvents. They utilize a unique junction that is highly conductive (<10 K ?) but not porous. There is no solution migrating through the junction in either direction. The reference is totally leak free! The junction is resistant to most commonly used organic solvents. It offers excellent resistance to acetonitrile, DMSO, THF, MEK, acetone, dichloromethane, esters, alcohols, and ketones, hydrofluoric acid or common dilute acids and bases. Unlike conventional reference electrodes, there is no need to store them in concentrated chloride solution. If the electrode is left dry for a long period of time, it should be immersed in water for few hours to recover.
