The rotating disk electrode (RDE) and rotating ring-disk electrode (RRDE) are the standard tools for hydrodynamic voltammetry: by rotating the working electrode you fix mass transport mathematically and you can extract kinetics, transfer coefficients, electron-transfer numbers and reaction intermediates from a single experiment. This page lists rotating disk electrode systems (OrigaTrod) and full rotating ring-disk electrode setups (RRDE) for oxygen reduction reaction (ORR) studies, electrocatalyst screening (Pt/C and non-PGM catalysts), corrosion analysis and reaction mechanism work. RDE and RRDE systems are research-grade and configurations vary by motor, shaft and interchangeable tip. Request a quote with your shaft and tip requirements.
