Rotating Ring Disk Electrode

RRDE-3A Rotating Ring Disk Electrode Apparatus Ver.3.0

RRDE-3A is a miniature rotator system for use in constant rotation and hydrodynamic techniques by rotating ring disk electrode in electrochemistry field. A short stainless steel shaft and 12 mm diameter electrode provide a concentric circle electrode system that is capable of high accuracy.

RRDE-3A is electronically controlled by a proportional-integral closed loop circuit driven by a DC servomotor. The compact electrodes are easily and rapidly interchangeable. The unit also provides an adjustable valve system for inert gas purging inside the cell vial.

RRDE-3A can be operated as a stand-alone unit and directly controlled by Model 2325 or other instruments. During or between electrochemical analyses, a built-in gas control allows purging the sample.
Besides, easy to remove and replace the cell vial, easy for rinsing, cleaning, and replacing electrodes.

Improvement points of Ver.3.0

RRDE-3A Ver.3.0 is electronically controlled by a proportional-integral closed loop circuit driven by a DC servomotor. The main frame structure has been improved and the weight of the instrument has been reduced from 6.0 Kg to 3.5 Kg.

Design changes

  • The position of the power switch has been changed from the back to the front (next to the LCD display) (easy to operate).
  • The color of the LCD display changed from green to blue.
  • The clear warning button on the back has been removed. It is operated by the built-in software (easy to operate).
  • The built-in power supply is changed to an external power supply (for easier maintenance of the instrument).

New maintenance mode for the software

The new maintenance mode has been added to the software to facilitate the operation of the instrument and to help customers to keep track of the rotational wear and tear of the instrument, and to regularly clean and maintain the mechanical system in order to keep the instrument in optimum working condition.

RRDE-3A Ver.3.0 can perform the following settings in the maintenance mode added by the software:

  • Rotation speed setting unit change
  • Display of total rotation time and time to next warning
  • Clear warning display
  • Remote control input voltage monitoring
