This product is a high-purity platinum electrode designed for advanced electrochemical research, energy materials testing, and analytical applications. Manufactured by Tianjin Aida, the series includes seven models (Pt105 to Pt160) with platinum wire diameters ranging from 0.5 mm to 6 mm, all featuring 99.99% purity for reliable and reproducible measurements. Each electrode is housed in a PTFE sleeve with a length of 60 mm and a copper terminal of 20 mm, ensuring chemical resistance and stable electrical contact. The electrode body has a total length of 80 mm, with sleeve diameters varying from 6 mm to 12 mm to accommodate different experimental setups. These electrodes are commonly employed in cyclic voltammetry, impedance spectroscopy, and as working or counter electrodes in electroanalytical and energy conversion studies.
