The Compact Pine Rotator (CPR) integrates the motor controller unit, motor unit, and shaft into a single-piece rotator body. The built-in shaft is compatible with standard rotating disk electrode (RDE) and rotating cylinder electrode (RCE) tips. This rotator offers a simple and economical solution for routine hydrodynamic voltammetry.  While most customers enjoy the flexibility of the MSR rotator, the CPR may be useful for any of the following reasons:

  • Limited lab bench space is available - the CPR is slightly smaller without a separate control unit
  • You do not ever require rotating ring-disk electrochemistry in your research program
  • Your laboratory operates on the industrial scale and fewer options is preferred for SOP

Compact Pine Rotator (CPR)

  • The CPR rotator features a solid-state controlled servo-system capable of rotating an electrode at rates between 100 and 8,000 RPM. The electrode rotation rate is set using a convenient digital push button pot located on the front panel of the control box. The actual rotation rate is calibrated to within 3% of the front panel setting.

    The entire apparatus is easily taken apart and reassembled, and this facilitates locating the rotator in recessed spaces and in glove boxes. The main body of the rotator is easily raised or lowered with respect to the cell platform, making immersion or removal of the rotated electrode quick and easy. The base is made from a chemically resistant material.

    A group of banana jacks on the back panel of the CPR rotator provide flexible control of the rotator motor. One jack is a voltage input that can be used to control the rotation rate of the electrode (4000 RPM per volt). Another jack is a voltage output signal that is proportional to the actual rotation rate (1000 RPM per volt). A third jack is a TTL signal input that can be used to turn the motor on or off. Other jacks provide a signal ground (DC common) and a chassis ground.
