Gold (Au) working electrode is chemically stable, is a typical working electrode. Gold Disk working electrode is most commonly used electrochemistry measurements, for e.g. Cyclic Voltammetry.

Electrode size is as shown in the figure. The gold diameter is 2.0 mm. and the Electrode body material is Teflon. The Outside diameter is 1/4(inch); 6.35 mm. with gold plated connector for connecting to system. The total length of the electrode is 100 mm
