This Graphite Counter Electrode features a 0.250″ OD x 12″ long graphite rod seated inside a fritted glass tube by means of a 7 mm OD 14/20 PTFE adapter. The fritted glass tube isolates the counter electrode from the main test solution. The glass tube features a 24/25 taper joint for use in a 24/25 port on our OpenTop corrosion cells. Alternatively, the graphite rod may be removed from the glass tube and mounted directly in the electrochemical cell through a 14/20 side port.
