Electrode Rotators

Electrode rotators allow users to study a redox reaction with controlled hydrodynamic steady-state conditions, giving access to valuable kinetic information. the rotation rate can be controlled externally by applying an input signal to a pair of jacks on the front panel.

Electrode Rotators

Rotating disk (RDE), ring-disk (RRDE), and cylinder (RCE) electrodes may be used with this rotator. The rotation rate of the electrode may be precisely controlled using a four digit push-pot control on the front panel. The rotation rate is adjustable to within 1% of the control setting over a range from 50 to 10,000 RPM. A voltage output signal that is proportional to the rotation rate is available on the front panel. This signal may be used to accurately monitor the rotation rate during an experiment using a voltmeter or other data acquisition system.

If desired, the rotation rate may be controlled externally by applying an input signal to a pair of banana jacks on the front panel. This allows the rotation rate to be modulated by a sine wave, square wave, or other type of waveform. The outstanding acceleration characteristics of the system allow the rotation rate to follow the input signal with very little error. This feature is particularly desirable for use in hydrodynamically modulated applications.
