Overview

The RRDE-6A rotating disk electrode is widely used in modern electroanalytical chemistry, electrode processes, and homogeneous chemical reaction research. When the rotating disk electrode rotates itself, it can cause the solution to undergo regular motion (i.e. laminar motion) on the electrode surface, and the thickness of the diffusion layer on the electrode surface varies with the speed of rotation. Therefore, the convection diffusion equation can be accurately decomposed, which is a rare special case in electrode reaction kinetics.

Product Details

RRDE-6A typeRotating disk electrodeIntroduction

Widely used in chemical power sources; electroplate; Metal corrosion; Electrochemical reaction intermediates; Material researchOxygen reduction reaction（ORR）；Oxygen evolution reaction（OER)Research and Evaluation of Hydrogen Fuel Cell Catalysts; Research on lithium air batteries;Characterization of fuel cell catalysts, metal corrosion, and other electrochemical kinetic studies.With a constant potential meter/Electrochemical workstation combination (the ring electrode must be used in conjunction with a dual potentiostat or an electrochemical workstation with dual potentiostat function)

The instrument is connected by an upper motor and a motor drive, and the transmission between the motor and the spindle is achieved through a universal joint. The electrode head is installed at the lower end of the spindle, and a threaded connection is used to accommodate multiple electrodes. The spring pin on the shaft maintains contact with the electrodes.

The host is equipped withRDE and RRDE dual function, operating software, speed can be manually controlled or remotely controlled from the electrochemical workstation
Capable of rotating coating status function

Swiss imported motor, with rotating shaft components that can move up and down, horizontally or upside down, for easy coating and modification of working electrodes
