670 electrolysis workstation
The 670 Electrolysis Workstation is a turnkey, fully integrated platform purpose-built for advanced electrolysis research.
Whether youโre 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 COโ 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 (ยฑ20 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.
ADVANCED DIAGNOSTICS
The 670 is built not just to run experimentsโbut to help you understand them.
-
- Electrochemical Analysis – Perform advanced characterization with Electrochemical Impedance Spectroscopy (EIS) and High-Frequency Resistance (HFR) measurements, along with whole-cell and half-cell measurements using reference electrodes. IR-corrected measurements improve accuracy, and optional integration with the 857 enables enhanced impedance analysis during electrolysis experiments.
-
- Real-Time Monitoring – Track voltage and current continuously while running automated experiment sequences. All testing is managed through FlowCellยฎ software, which streamlines experiment control, data collection, and system visibility during operation.
-
- Flow & Reaction Insight: Study how operating conditions influence performance with control over gas and liquid environments, support for single-pass or recirculating operation, and sampling options for downstream product analysis.
FlowCellยฎ Software
FlowCellยฎ software provides a streamlined environment for operating the 670 Electrolysis Workstation, giving researchers a clear and efficient way to control experiments, monitor system performance, and capture high-quality data. The interface is designed to make experiment setup straightforward while still supporting the complexity often required in electrolysis research. Real-time system monitoring keeps key parameters visible throughout testing, while automated workflows help simplify longer or more advanced experimental sequences. Integrated diagnostics and data logging ensure that results are recorded clearly and consistently, making analysis and comparison easier across experiments.
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.
