Rotating Ring–Disk Electrode (RRDE) | Male Thread | PINE-Compatible

Glassy Carbon / Platinum / Gold Disk Options · Precision Ring Geometry · PTFE Body

Product Overview
The FrankLab Rotating Ring–Disk Electrode (RRDE) is a high-precision hydrodynamic working electrode designed for advanced mechanistic electrochemical studies. This RRDE features a central disk electrode and a concentric metal ring electrode, enabling real-time detection of reaction intermediates and quantitative kinetic analysis.
Fully compatible with PINE-style male-thread rotators, this RRDE provides exceptional stability, reproducibility, and accuracy for catalytic evaluation, ORR selectivity studies, EC/CE pathway analysis, and more.
