Ivium RRDE

Ivium rotator for RDE and RRDE measurements

The Ivium Rotating Ring Disk Electrode (RRDE) is a robust rotator designed for hydrodynamic electrochemical applications in combination with a potentiostat. 

It can be used for both hydrodynamic measurements

  • disk RDE: Rotating Disk Electrode) 
  • ring-disk (RRDE: Rotating Ring Disk Electrode) 

The combination with Ivium (bi-) potentiostats is recommended as the control is fully integrated in IviumSoft. However, the IviumRRDE can be used with any other suitable potentiostat.

 Potentistat or analog control

The rotation speed can be controlled with up/down buttons on the front panel of the control box, or from an external analog signal. 

The applied and measured rotation speeds are also displayed on the front panel.
