RDE-2 Rotating Disk Electrode

The BASi® RDE-2 is a rotator system for both fixed rotation rate and hydrodynamic modulation rotating disk electrochemical experiments. The short titanium shaft and 1/4" diameter electrode provide for an extremely low-inertia system capable of rotation rates from 50 to 10,000 RPM at better than 1% accuracy. The rotator unit is manually raised and lowered, and can be inverted for spin-coating. Rotation and built-in gas purging functions can be controlled remotely using a BASi® PC-controlled potentiostat, or manually.

The built-in gas control allows purging or blanketing of the sample prior to or during analysis. The cell arm with detachable cell top allows easy access to the electrodes for rinsing and cleaning, and the cell top is also compatible with BASi® voltammetry working electrodes. Electrodes are easily interchangeable, and the cell vial base pivots for easy removal and replacement of the cell vial.
