CHEMICAL INCOMPATIBILITIES: Some non-aqueous solvents may cause damage, leakage, or swelling to the epoxy tube and electrode.
This Standard Platinum Counter Electrode 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 PTFE adapter suitable for mounting the tube in a 14/20 port on our standard electrochemical cells. Alternatively, the counter electrode may be removed from the glass tube and mounted directly in the electrochemical cell. The coil is fabricated from a 0.5 mm OD Pt wire that has an approximate surface area of 4.7 cm2. The approximate diameter of the coil is 9 mm. The 6.9 mm OD black epoxy rod is 150 mm long. The overall length of the rod and the coil is approximately 180 mm.
