Coiled Platinum Counter Electrode
This counter electrode design features a coiled platinum wire (99.99% pure) mounted at the end of a chemically-resistant epoxy rod. A fritted glass tube isolates the counter electrode from the main test solution.

The glass tube is equipped with a Teflon adapter suitable for mounting the tube in a 14/20 side port on the electrochemical cell. Alternately, the platinum rod may be removed from the glass tube and mounted directly in the electrochemical cell.

The coil is fabricated from a platinum wire (0.5 mm OD) that is 29.0 (+/- 1.0) centimeters long. The approximate surface area of the platinum coil is 4.7 square centimeters. The approximate diameter of the coil is 9 mm. The black epoxy rod (6.9 mm OD) is 150 mm long. The overall length of the rod and the coil is approximately 180 mm.
