Rotational Speed of Rotating Disk Electrodes

Posted by gamry on October 2, 2018

Since the mid-20th century, rotating disk electrodes (RDEs) have been used to provide a steady stream of reactants “uniformly accessible” to the surface of a disk.

Care of Porous Glass Frits

Posted by gamry on January 24, 2018

Porous glass frit is often used at the end of a reference electrode or a bridge tube to allow electrical, ionic conductivity between the bulk of the solution and the internal filling solution, while preventing large scale convective mixing of the solutions.
