This product is designed for researchers in electrochemistry, energy materials, and analytical applications, offering a high-purity platinum mesh electrode with a PTFE outer jacket for reliable performance in corrosive or high-temperature environments. The platinum mesh, with a purity exceeding 99.95% and a 52-mesh configuration, ensures excellent conductivity and catalytic activity, making it suitable for use as a working or counter electrode in electrochemical cells, battery research, and sensor development. Available in both rectangular and circular sizes, including 10×10 mm and 20×20 mm, the electrode can be customized to meet specific experimental requirements. The electrode features a 20 mm terminal and a 60 mm jacket, with a total length of 80 mm, while alternative models offer a gold-plated terminal for oxidation resistance. These characteristics support reproducible measurements in fundamental studies and applied energy research.
