For corrosion testing, electrocatalysis screening, metal dissolution studies, deposition kinetics and any experiment where the working-electrode material is the experimental variable, base-metal working electrodes cover the full relevant range: copper electrode, aluminium (aluminum) electrode, zinc electrode, nickel electrode, titanium electrode, tungsten electrode (Wolfram), lead electrode, iron electrode, cadmium electrode and palladium electrode, all in 2 mm and 3 mm disk diameters. This page also lists PEEK-bodied working disk electrodes and high-pressure disk electrode formats for autoclave and high-temperature electrochemistry.
