This product is designed for CO₂ electrochemical reduction studies, functioning as a flow cell device suitable for a range of electrolysis experiments including water splitting and ammonia oxidation. The cell body incorporates a PEEK working electrode block with an integrated flow channel, paired with a PTFE reference electrode block featuring a 10×10 mm internal cavity, ensuring chemical resistance and stability under electrochemical conditions. Both working and reference electrodes must be supplied by the user, with a silver/silver chloride reference electrode recommended for consistent potential control. The modular design allows customization of dimensions to meet specific experimental setups. Available configurations include a version with electrode rods for fixed electrodes and a sheet electrode variant, offering flexibility for different research requirements. This device is particularly relevant for laboratories investigating carbon dioxide conversion and sustainable energy materials, providing a robust platform for evaluating catalytic performance under controlled flow conditions.
