Chemical Compatibility Caution Notice
PEEK dissolves with long exposure to concentrated acids.
Thermal Stability Range: 10°C - 80°C
Electrode damage may occur at temperatures beyond recommended range. This range is provided for electrodes with PEEK shrouds.
Compatibility Notice
Avoid using this reference electrode with the following: NH3 buffers, sulfides, perchlorates, non-aqueous/organic solvents, and alkaline solutions stronger than 0.1M OH–.
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.
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: 3000 RPM
Never exceed maximum rotation rate when working with rotating electrodes.
Fragile Material Warning
Platinum wire is fragile. While it can be formed into a shape, repeated bending will cause the wire to break. In almost all cases, this is irreversible and cannot be repaired. Do not bend platinum wire.
Consumable U-Cups!
The PTFE U-Cup is a consumable product for the ChangeDisk RDE and RRDE tips. To ensure proper operation and longevity of the tip, Pine Research recommends replacing the U-Cup every 4-5 times you perform a ChangeDisk operation. Permanent, irreversible damage to the tip will result if the U-Cup is not regularly changed. Consider purchase a backup supply when ordering a new ChangeDisk RDE or RRDE tip.
MSR evo Electrode Rotator
The MSR evo Electrode Rotator is an evoLUTION of the world's most popular rotator, the Modulated Speed Rotator (MSR). This flexible electrochemical instrument may be used with Rotating Disk Electrodes (RDE), Rotating Ring-Disk Electrodes (RRDE), and Rotating Cylinder Electrodes (RCE). The MSR evo Rotator is compatible with most international power configuration standards. The MSR evo Rotator shares many of the same technical specifications as the MSR, with a few exciting updates:
- Rotation range increase: 0 to 10,800 RPM
- Improved and revised control unit electronics, for improved stability.
- Updated control unit is smaller, modern, and better laid out.
- Added Pause/Run button to front panel (as found on the WaveVortex 10 Electrode Rotator).
- Bright LED display on front panel replaced old LCD.
- Continues to use the same RDE, RRDE, and RCE electrodes as the original MSR.
- New USB port on control unit means new smart features possible.
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 output signal from an electrochemical workstation or third-party waveform generator. The rotation rate shines brightly on the new blue LED display on the control unit. The rotation rate is adjustable over a range from 50 to 10,800 RPM and is accurate to within 1% of the reading on the display. Rotation rate may also be monitored via an output signal proportional to the rotation rate, accesible on the control unit input/output connector.
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.
E8R4 Series High Efficiency Fixed Disk Rotating Ring-Disk Electrode (RRDE) tip
The E8R4 Series High Efficiency Rotating Ring-Disk Electrode (RRDE) with Platinum Ring and Glassy Carbon Disk has the highest collection efficiency of any RRDE electrode on the market, 43.9%! This tip features a 15 mm OD PEEK shroud, 5 mm OD glassy carbon disk, and 1.25 mm thick platinum ring. The tip threads into the Precision RDE/RRDE Shaft for E5, E5TQ, E6, E7, and E8 Series Tips, which is then installed into the MSR evo Electrode Rotator. Pine Research offers more electrode in more materials than anybody else. Check out all the other MSR evo compatible RRDE tips we offer.
