Introduction
RRDE-3A is a constant rotation system for use in hydrodynamic
modulation rotating ring disk electrochemistry. A 7 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 a potentiostat. 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.
