Mini Pt Coil Electrode with Teflon Body

The counter electrode (or auxiliary electrode) closes the circuit in a three-electrode cell, carrying the current required to drive the working-electrode reaction without polarizing the reference. Its job is to be chemically inert, low-impedance and large enough not to limit the experiment. ElectroSeek aggregates more than sixty counter electrodes: graphite rod electrodes (4 mm and 6 mm diameters), platinum in every common geometry (wire, mesh, gauze, sheet, foil, plate, coil, ball, lamina, flag, ring), MMO ruthenium-iridium coated titanium, rhodium-plated meshes and foams, glassy-carbon rods, gold wires, silver and generic stainless-steel auxiliary electrodes for corrosion and high-pressure setups.
