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 WaveVortex 10 rotator has a maximum rotation rate. Do not the exceed maximum rotation rate when working with rotating electrodes.
The WaveVortex 10 Electrode Rotator is designed to suit the needs of those looking to perform rotating disk (RDE) and rotating ring-disk (RRDE) electrode experiments with limited lab space. This small footprint rotator is compatible with all 15 mm OD RDE/RRDE electrodes manufactured by Pine Research, along with many of our cells, glassware, and accessories.
The control box, motor, shaft, and enclosure are all fixed into one convenient unit, making the WaveVortex compact and portable. The rotation rate can be manually adjusted on the front panel and monitored on the digital display. Alternately, a potentiostat can control the rotation rate using an appropriate rate control cable.
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.
