Glassy Carbon Rotating Disk Electrode (GC RDE)

Overview

The Glassy Carbon Rotating Disk Electrode (GC RDE) from ScienceGears is designed for high-precision kinetic and mechanistic electrochemical studies under controlled hydrodynamic conditions. The inert and smooth glassy carbon surface ensures excellent reproducibility, low background current, and chemical stability across a wide potential window, making it ideal for both aqueous and non-aqueous systems.

Principle of Operation

The RDE system generates a laminar flow of electrolyte toward the electrode surface through controlled rotation. This allows quantitative evaluation of diffusion-limited currents and electron-transfer kinetics. The glassy carbon disk provides a chemically inert and stable substrate suitable for surface modification, catalyst deposition, and electrochemical cleaning.
