RRDE-6A modelRotary Disc ElectrodeIntroduction
Widely used in chemical power sources; electroplating; metal corrosion; electrochemical intermediates; material researchOxygen Reduction ReactionORR）；Oxygen Evolution ReactionOER）Hydrogen Fuel Cell Catalyst Research and Evaluation; Lithium-Air Battery ResearchFuel cell catalyst characterization, metal corrosion, and other electrochemical kinetics research areas.With a potentiostatChemical Workstation Coupling (Ring Disk Electrode must be coupled with a Dual Potentiostat or a Chemical Workstation with Dual Potentiostat Function)
The instrument is connected by a motor at the top and a motor-driven coupling, which transmits power through a universal joint between the motor and the main shaft. At the bottom of the main shaft, an electrode head is installed. It features a threaded connection for compatibility with various electrodes, maintaining contact with the electrode by a spring-loaded pin on the shaft.
The main unit featuresRDE and RRDE dual-function, operation software, speed can be manually controlled or remotely controlled by electrochemical workstation
Features a rotating coating state function
Swiss-imported motor, rotating shaft components are adjustable for up and down movement, lateral and inverted positions for convenient coating and finishing of the working electrodes.
