Description
The RRDE-3A is a compact electrochemical rotator system designed for hydrodynamic electrochemistry using rotating disk or ring-disk electrodes. It provides precise control of mass transport by rotating the electrode at controlled speeds. The system uses a DC servo motor with closed-loop control, ensuring accurate and stable rotation. It also includes a built-in gas purging system, allowing experiments under low-oxygen conditions. Its modular design enables easy electrode exchange and compatibility with various potentiostats, making it suitable for advanced electrochemical research.
