Multi-Function RRDE system
4-in-1 Electrochemical System for RDE, RRDE, Spin Coating & Electro-Spinning
4-in-1 Electrochemical System for RDE, RRDE, Spin Coating & Electro-Spinning
A multifunctional electrochemical platform combining rotating disk and ring-disk measurements with advanced spin coating and voltage/current-assisted electro-spinning, ideal for catalyst development and surface engineering.
Highlights
This multifunction RRDE system is a high-precision 4-in-1 electrochemical platform that supports RDE, RRDE, spin coating, and electro-assisted spin coating (electrospinning-like) applications. Designed for seamless integration with any electrochemical workstation, including those with bipotentiostat functionality, the system enables researchers to fabricate, modify, and test catalytic electrodes within a single compact setup.
With a constant-speed, low-vibration motor and support for both disk and ring-disk configurations, the multifunction RRDE is ideal for mechanistic studies and kinetic analysis in advanced electrocatalytic research areas such as HER, OER, ORR, HOR, and CO₂ reduction. The added ability to perform voltage-assisted spin coating allows precise control of film morphology and adhesion, offering new capabilities for in-situ catalyst layer engineering.
