Description

This bundle includes an E8 Series High-Efficiency RRDE tip with a fixed platinum ring and a fixed glassy carbon disk.  As your research grows, you can expand your rotating electrode collection to include a wide variety of additional RDE, RCE and RRDE tip designs that are compatible with the Pine Research MSR Rotator.

MAXIMUM ROTATION RATE: Each electrode tip model used with the Pine Research MSR Rotator has a maximum rotation rate. Do not the exceed maximum rotation rate when working with rotating electrodes.

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 contacts – the red is for the disk, and the blue is for the ring.
