Working classic electrode designed for routine use as (non-rotating) working electrodes.
The WCE is a glass rod with a Pt (WS.D1-3) or Au (W1.D4) wire inside. The electrode ends with polished active surface of 1 or 2 mm2. Only the cross section of the metal wire is exposed and so a metal disc electrode is formed. The working classic electrode (WCE) fits in the NJ 10/13 side openings of the TC4, TC5, TC6 glass cells.
