670 electrolysis workstation
Scribner
The 670 Electrolysis Workstation is a turnkey, fully integrated platform purpose-built for advanced electrolysis research.
Whether you’re a university research lab, a startup developing next-generation electrolyzers, or an industrial R&D group scaling electrochemical processes, the 670 delivers exceptional control, flexibility, and measurement accuracy.
Designed to support both liquid and gas-phase operation at one or both electrodes, the 670 enables precise investigation across a wide range of electrolysis conditions. From CO₂ reduction and ammonia synthesis to power-to-fuels, syngas production, and electrochemical separations, the system provides reliable performance for modern electrochemical research. With integrated high-current potentiostatic/galvanostatic control (±20 A), electrochemical impedance spectroscopy (EIS), and coordinated control of reactant flow and temperature, the 670 allows you to focus on reaction insights, not system complexity.
Configure the System for Your Research
The 670 platform is built with flexibility in mind, allowing the system to be configured to match your specific experimental setup. A range of system options and accessories makes it possible to adapt the workstation to different cell configurations, operating conditions, and research goals. As your work evolves, the modular design allows the system to grow with your research, supporting new experiments and expanded capabilities over time.
