Glassy Carbon Rotating Disk Electrode (GC RDE)
GC Rotating Disk Electrode (RDE) 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.
Key Specifications
- Electrode Material: High-purity glassy carbon disk
- Disk Diameter: 5 mm standard (custom sizes available)
- Body Material: PTFE or PEEK for solvent and chemical resistance
- Electrical Contact: Gold-plated connector for stable conductivity
- Surface Finish: Polished to mirror finish for low background noise
Applications
Ideal for:
- Electrocatalyst characterisation and ORR/OER studies
- Fuel cell and redox mediator evaluation
- Battery electrode testing and sensor calibration
- Electropolymerisation and thin-film deposition research
