670 Electrolysis Workstation
670 Electrolysis Workstation
The 670 Electrolysis Workstation is a comprehensive, customizable platform capable of accommodating both liquid and gas on one or both electrodes. It features a multi-range, high-current (±20 Amp) potentiostat, ensuring high accuracy across a wide range of reaction rates and cell sizes. The system includes the powerful and user-friendly FlowCell® software for system operation and experimentation. With numerous accessory options available, you can tailor this system to suit your specific research needs. It is particularly well-suited for Electrolysis and Desalination by Capacitive Deionization studies, as well as applications such as Power-to-Fuels & Power-to-Chemicals, CO2 Reduction, Low Temperature CO & Syngas Production, Electrochemical Ammonia Synthesis, and Organic Electrosynthesis.
