Overview
Install a glassy carbon electrode on the rotating shaft, which is a rotating disk electrode. Replacing platinum ring electrodes with rotating ring disk electrodes is widely used in chemical power sources; electroplate; Metal corrosion; Electrochemical reaction intermediates; Materials Research Oxygen 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. Used in conjunction with a potentiostat/electrochemical workstation (the ring electrode must be used in conjunction with a dual potentiostat or an electrochemical workstation with dual potentiostat functionality)
Product Details
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 withRDEandRRDEDual function, Kehuan operating software, speed can be manually controlled or remotely controlled from the electrochemical workstation
