616A Rotating Disk Electrode

A RDE system uses a single potentiostat to polarize a Disk electrode.  Rotation of this disk electrode encourages mass-transport of ions in solution to the electrode surface.  This increased flux benefits physical electrochemistry applications, such electroplating and fundamental research.

A RCE system uses a larger area electrode that is a different form.  This is common configuration for studying velocity-sensitive electrochemical corrosion such as in an oil and gas pipeline.

For RRDE system, please inquire about our model 636A Electrode Rotater.
616A Rotating Disk Electrode
The Princeton Applied Research Model 616A Electrode Rotator is a high precision, low mass rotator for use with any potentiostat. When connected to many Princeton Applied Research potentiostats, it uses control lines to give a remote start/stop and speed control.  Using the convenient control panel and input jacks, the model 616 can easily be operated for either manual or automated experiments.

Standard features include:
  • Integrated shaft (arbor)
  • Front panel speed control and remote analog speed control
  • Front Panel and remote (TTL) on/off switching (using Princeton Applied Research stir-control signals)
  • Protective enclosure
  • Model variants for local power 616A for 110V and 616B for 220V.
A variety of disk materials are available in different electrode materials, including the popular Pt, Au, and Glassy Carbon (GC), as well as different shroud materials.
