The best way to work with a Pine Research Rotating Ring-Disk Electrode (RRDE) system is to pair it with a Pine Research electrochemical workstation. This bundle gets you started with a WaveDriver® series bipotentiostat-galvanostat, an E8 Series High-Efficiency RRDE tip, and a Pine Research Modulated Speed Rotator (MSR) – the most popular electrode rotator in the world. The High-Efficiency RRDE tip features a fixed platinum ring, a fixed glassy carbon disk, and the highest collection efficiency (43.9%) of any RRDE tip available on the market.

Every purchase of a Pine Research potentiostat and rotating electrode bundle includes a free one-hour online training session! Contact Pine Research now (click here) to learn more and to schedule your training session.

Under the control of our powerful AfterMath® software package, the WaveDriver 200 is capable of performing Electrochemical Impedance Spectroscopy (EIS) and a wide range of DC electroanalytical techniques including hydrodynamic voltammetry.  This instrument is a truly integrated bipotentiostat with a convenient cell cable that allows quick and easy connection to a rotating disk electrode (RDE) or rotating ring-disk electrode (RRDE).

The versatile Pine Research MSR Rotator lets you get started immediately with hydrodynamic experiments. This RRDE start-up bundle includes the following principal items along with compatible cables and accessories:

  • WaveDriver 200 EIS Bipotentiostat/Galvanostat
  • Pine Research MSR Rotator
  • High-Efficiency RRDE tip (glassy carbon disk, Pt ring, 43.9% collection efficiency)
  • Pine Research AfterMath Software
  • Jacketed RDE Cell (glass) with Pt Counter and Ag/AgCl Reference Electrode

The WaveDriver 200 EIS Bipotentiostat/Galvanostat is the most complete electrochemical workstation offered by Pine Research.  Unlike other “bipotentiostats” on the market, this instrument has a truly integrated bipotentiostat circuit by design.  Because the second working electrode is fully-integrated into the design, the instrument is ready to use out of the box, the cell cable has convenient electrode leads for both the first and second working electrodes (no messy cable configurations necessary), and no additional adapters or connectors are required to perform true dual working electrode experiments like rotating ring-disk voltammetry.  Further, the WaveDriver 200 finds use across a wide variety of applications with current ranges up to ±1 Amp, potential ranges up to ±15 V, advanced input, output, and waveform filters, iR compensation, and EIS up to 1 MHz.

Our talented team of engineers and chemists have taken a careful approach at integrating EIS into our WaveDriver series potentiostats.  Our software engineering team has incorporated EIS equivalent circuit fitting directly into our AfterMath® software platform.  Multiple curve fitting algorithms and options allow you to fit even the most troublesome data.  This instrument is a cost-effective tool you can use to make a wide variety of electrochemical measurements in your research work.  The unique features of the WaveDriver 200 are summarized below.

Cost-Competitive.  Take a look around at similar bipotentiostat/galvanostat systems and you will have a difficult time finding another with comparable specifications and capabilities at the price of the WaveDriver 200.  While you may find a single-channel EIS-capable potentiostat at a similar price, the WaveDriver 200 gives you a built-in second working electrode without having to purchase a second channel.

Integrated Curve Fitting and Analysis.  Our software team has seamlessly integrated EIS curve fitting into AfterMath.  Why work with more than one software application to fit your EIS data when you can do it using the very same software application that acquired the data?  AfterMath EIS curve fitting utilities provide several analyses, including Circuit Fit, Transmission Line, and Kramers-Kronig.  Unlike others, our fitting software also provides several fitting methods including Modified Levenberg-Marquardt (LM), Simplex, and Powell algorithms in addition to fitting options that include dynamic point selection, unity, and parametric fitting.

Novel Transmission Line Fitting.  AfterMath provides a unique approach to model your porous electrodes.  While the transmission line model is not new, AfterMath provides you with some unique transmission line fitting tools.  Instead of a static circuit, where you have no control over the elements of the model, we provide a very flexible basic model, from which you can customize nearly all aspects of the model to suit your system.  Give it a try – import your three- or five-column EIS data directly into AfterMath and see the difference with our transmission line fitting.

Finishing Touches.  While fitting your EIS data, why flip back and forth between Nyquist and Bode plots?  Why not be able to view both plots and fits simultaneously?  We heard this feedback from many customers and have designed AfterMath to provide you with both plots simultaneously during fitting.  You can also draw your own equivalent circuits to fit your particular system.

What makes the WaveDriver 200 bipotentiostat even more powerful?
Combining it with a precision electrode rotator manufactured by Pine Research…

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