Overview
Rotating Disk Electrodes (RDE) and Rotating Ring-Disk Electrodes (RRDE) are essential tools in modern electrochemistry, enabling researchers to study reaction kinetics under well-defined hydrodynamic conditions. By rotating the electrode, a stable diffusion layer forms at the surface, allowing accurate determination of reaction rates and transport behaviour. ScienceGears offers high-quality RDE and RRDE electrodes engineered for precision, durability, and compatibility with leading potentiostat systems used across Australia and New Zealand.

FAQs
1. What is the principle behind a Rotating Disk Electrode (RDE)?
An RDE rotates to generate a controlled laminar flow of electrolyte, forming a steady diffusion layer that allows precise kinetic and mass-transport measurements.
2. How does an RRDE differ from an RDE?
An RRDE adds a ring electrode surrounding the disk to capture intermediates or products, enabling detailed mechanistic studies of multi-step electrochemical reactions.
3. Which potentiostats are compatible with RDE/RRDE setups?
Any potentiostat supporting standard three-electrode configurations and rotation control can be used.
