The working electrode holder is suitable to hold a working sample of thickness up to 5mm. This design incorporates a gold-coated copper clip and a chemically stable PTFE body. Simplifying electrode handling, it employs a user-friendly mini alligator clip. The 8mm shaft, in conjunction with the B14 movable holder, not only facilitates seamless integration with MTX electrochemical cells (B14 sockets) but also accommodates cells with hole sizes ranging from 12mm to 14mm. The inclusion of a flat jaw alligator clip ensures the protection of samples from damage, while the movable B14 cone allows for easy adjustment of immersion length. Beyond these features, the holder offers versatility and user-friendly operation, making it an indispensable tool in various electrochemical setups. Gold-coated connecting rod 2mm diameter helps to link the electrode holders to potentiostats and galvanostats for precise control of potential and current.
