Eliminate problems associated with the use of conventional porous junction-based reference electrodes.
Leak Free reference electrodes utilize a unique junction that is highly conductive (< 30 kΩ) but not porous. There is no solution migrating through the junction in either direction making the reference 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, ketones, and hydrofluoric acid or other common dilute acids and bases.
Unlike conventional reference electrodes, there's no need to store these electrodes 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.
Leak Free reference electrodes are available in two sizes, and custom configurations are possible.
The Low-Leakage reference electrodes are designed for use in applications where contamination would interfere with the application.
The electrode junctions are resistant to most commonly used organic solvents. They offer excellent resistance to acetonitrile, DMSO, THF, MEK, acetone, dichloromethane, esters, alcohols, and ketones. Hydrofluoric acid or common dilute acids and bases also have no effect on the on these electrodes.
Two low-leakage reference electrodes are available. One is 2 mm (0.08 in) in diameter and the other is 5 mm (0.2 in) in diameter. Custom configurations are possible.
