Specify Power Cord

This product requires a power cord to connect to AC mains. Please specify the plug style used in your region when you order this product. We stock a variety of power cords.

Maximum Rotation Rate

All rotating electrodes, including RDE, RRDE, and RCE, have an assigned maximum rotation rate. The maximum rotation rate is specific to each electrode series. Do not exceed the maximum rotation rate when working with rotating electrodes.

Electrodes sold separately.

Given the wide range of electrodes we offer, rotators do not include electrodes (RDE, RRDE, RCE) and must be purchased separately. This way, you can select the perfect electrode for your applications.

Shafts sold separately.

Given the wide range of electrodes we offer, where each series requires one of several rotating shafts, shafts must be purchased separately for the MSR and MSR evo rotators. Consult the RDE, RRDE, and/or RCE specifications to learn which shaft is compatible.

The Pine Research MSR Rotator is the most popular rotating electrode configuration worldwide.  This flexible electrochemical instrument may be used with Rotating Disk Electrodes (RDE), Rotating Ring-Disk Electrodes (RRDE), and Rotating Cylinder Electrodes (RCE).  The MSR Rotator bears both the CE and ETL marks and is compatible with most international power configuration standards. The rotation rate of the electrode may be adjusted using a control knob on the front panel of the motor control unit, or alternately, the rotation rate can be controlled via an analog control signal provided by a potentiostat or by a third-party waveform generator.  The rotation rate may be viewed using the LCD display on the front panel.  The rotation rate is adjustable over a range from 50 to 10,000 RPM and is accurate to within 1% of the reading on the display.  A rotation rate may also be monitored via an output signal proportional to the rotation rate which is available on the front panel. The rotation rate may be controlled and modulated by a sine wave, square wave, or other externally generated waveform.  The outstanding acceleration characteristics of the motor and its control circuitry allow the rotation rate to follow the control waveform with very little error.  This feature is particularly desirable for techniques such as Hydrodynamic Modulation Voltammetry (HMV) . The rotator motor position is easily raised or lowered with respect to the cell platform, making immersion or removal of the rotating electrode tip quick and easy.  The enclosure base is made from chemically resistant polypropylene, and the large enclosure window provides a good view of rotating electrode during operation.  (A smaller base is available separately for using the rotator in a glove box or fume hood.) Electrode connections are made to the rotating shaft using silver-carbon brushes.  There are two pairs of contacts – the red pair is for the disk, and the blue pair is for the ring.
