Disc electrode:Simply replace with different rotating electrode tips on the rotating shaft. The standard rotating disk electrode comes with a 4mm glassy carbon electrode, and switching to a platinum ring electrode turns it into a rotating ring disk electrode.
Broadly used in chemical power sources, electroplating, metal corrosion, electrochemical intermediate bodies, material research on oxygen reduction reactions (ORR), oxygen evolution reactions (OER), research and evaluation of catalysts for hydrogen fuel cells, lithium-air battery research, characterization of fuel cell catalysts, metal corrosion, and other electrochemical dynamics studies. Compatible with potentiostats/electrochemical workstations (ring disk electrodes must be used with a dual potentiostat or an electrochemical workstation with dual potentiostat functionality).
Technical specifications and main features
The main unit features dual functions of RDE and RRDE, comes with the Keyhuan operating software, and the speed can be manually controlled or remotely operated by an electrochemical workstation (1V=1000rpm).
Features Spin-coating state functionality
The motor shaft component can be moved up and down, as well as rotated horizontally and inverted for convenient coating and finishing of the working electrode.
