Porous glass frits are, in many cases, the best material for use as reference electrode junctions. They offer relatively low electrical resistance and low leakage. In older literature, porous Vycor® made by Corning was cited. However, several years ago Corning discontinued making porous Vycor®. A similar material is available from Schott Glass, CoralPor™ 1000. These tips can be attached to glass tubes by heat shrink FEP tubing. Frit size is approximately 1/8″ (3.1 mm) diameter and 1/8″ (3.1 mm) length.
Note that these frits are not recommended for solutions that readily dissolve glass, such as strongly basic solutions.
