Product description

The IviumRRDE apparatus is a robust rotator for hydrodynamic electrochemical applications to be used in combination with a potentiostat. It can be used for both disk (RDE: Rotating Disk Electrode) and ring-disk (RRDE: Rotating Ring Disk Electrode) measurements. 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.

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.

Information on purchasing tips for RDE and RRDE experiments can be found here. The rotator stand and RRDE cell shown in the gallery images are not included, but are available as options.

The IviumRRDE apparatus kit includes:
• Rotator with driveshaft and brush assembly (no tips included):
• Motor-controller unit
• Connection cable
• Power supply 100-240V
• Rotator mounting bracket
• Easy carry hard case
