Platinum Gauze Electrode - OD: 23 mm, H: 20 mm

The counter (auxiliary) electrode provides a means of applying input potential to the working electrode. It completes the circuit and allows charge to flow between counter and working electrodes. Platinum is the most commonly used material for the auxiliary electrode, due to its alleged inertness, reaction speed and catalytic properties. 

Application Note:
Platinum Gauze Electrode is suitable for studies of many electrochemical processes in aqueous and organic media. Platinum is a well-known catalyst for water electrolysis (HER), direct ethanol fuel cells, organic electrosynthesis or oxidation of alcohols into organic acids. Thanks to the high surface area, this counter electrode is a perfect choice for electrochemical characterization of highly capacitive materials for energy storage applications.
