616A Rotating Disk Electrode

Highlights​​

​

• Rotating Disk Electrode (RDE) or Rotating Cylinder Electrode (RCE) Configuration

• Rotational Speeds to 8,000 RPM

• A variety of Fixed-Disk configurations: different electrode materials; PTFE versus PEEK shroud

• On/Off and Rotational Rate Control through DAC control of many potentiostats from Princeton Applied Research

Applications and Software​

​​​

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.
