RRDE-3A is a constant rotation system for use in hydrodynamic modulation rotating ring disk electrochemistry. A 12 mm diameter electrode with short stainless steel shaft provides for a miniature and concentric circle electrode system that is capable for highly accurate rotation and modulation even at radial modulation rates or wave forms.

A 12 mm diameter electrode with short stainless steel shaft provides for a miniature and concentric circle electrode system that is capable for highly accurate rotation and modulation even at radial modulation rates or wave forms.

RRDE-3A is electronically controlled by a proportional-integral closing loop circuit driving as an DC servo-motor. Electrodes are small and rapidly interchangeable. The unit also provides an adjustable valve system for inert gas purging inside the cell vial.

RRDE-3A is able to be operated as a stand-alone unit and directly controlled by CHI, BASi Electrochemical Analyzers or other instruments. When the analysis starts, a built-in gas control allows purging the sample. Besides, the access to glass cell is easy for rinsing, cleaning, and replacing the electrodes. It is easy to remove and replace the cell vial.
