This product, the Electrode Frame (model series MA-CM-AE-0033) from Tianjin Aida, is designed for electrochemical research and analytical electrode setups. Constructed entirely from tetrafluoroethylene (PTFE) and stainless steel, it offers excellent chemical resistance and mechanical stability for laboratory environments. The PTFE plate (150 mm × 120 mm) provides a robust base, while the stainless steel bracket (φ8 × 160 mm) ensures secure electrode positioning. Available in multiple capacity configurations (100 ml to 500 ml), this frame accommodates various cell volumes, making it suitable for experiments in energy materials, electrocatalysis, and battery testing. Its corrosion-resistant materials enable reliable use with aggressive electrolytes, supporting reproducible measurements in advanced material research and development.
