RRDE-3A

RRDE-3A

Rotating Ring Disk Electrode

This system has been designed for hydrodynamic (RDE or RRDE) measurements with a high level of accuracy for the control of electrode rotation and modulation.

The RRDE-3A is a system that can be used to perform hydrodynamic (RDE or RRDE) measurements. Its design (short stainless steel shaft) allows users to accurately control electrode rotation. The RRDE-3A is electronically controlled by a closed loop circuit driving a 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. Additionally, access to the glass cell facilitates rinsing, cleaning, and replacing the electrodes. It is also easy to remove and replace the cell vial. RRDE-3A can be operated as a stand-alone unit or directly controlled by a Bio-Logic electrochemical workstation.
