WaveDriver 200 EIS Bipotentiostat

The WaveDriver 200 EIS Bipotentiostat/Galvanostat has been engineered to provide you with the essential hardware and software features you need at an affordable price.  The most complete electrochemical workstation offered by Pine Research, the WaveDriver 200 combines the benefits of a true integrated bipotentiostat with Electrochemical Impedance Spectroscopy (EIS).

True Integrated Bipotentiostat. From the software to the cell cable design, everything about the WaveDriver 200 bipotentiostat makes working with dual working electrode configurations as straightforward as possible: no messy inter-channel connections are required, and no additional cell cables or adapters are required. The WaveDriver 200 connects to your laptop or PC via a standard USB cable and is controlled by our powerful AfterMath software. The software user interface is designed with two working electrodes in mind, so entering experimental parameters for dual-electrode techniques is quick-and-easy.

Applications. The WaveDriver 200 finds use in academic and industrial research laboratories around the world and across a wide variety of applications. The instrument offers a large range of accessible current ranges (±100 nA up to ±1 A) and potential ranges (±2.5V up to ±15 V) along with advanced filtering and iR compensation. Back panel connections allow rotation rate control when performing voltammetry using a Rotating Disk Electrode (RDE), Rotating Ring-Disk Electrode (RRDE), or Rotating Cylinder Electrode (RCE). Additional input/output and timing connections permit the WaveDriver to control third-party instrumentation in applications such as spectroelectrochemistry.

Electrochemical Impedance Spectroscopy. Our talented team of engineers and chemists have taken a careful approach to integrating EIS into our WaveDriver series potentiostats, giving you access to the most practical range of EIS frequencies (10 µHz to 1 MHz) at an affordable price. We have incorporated powerful and easy-to-use EIS equivalent circuit fitting directly into our AfterMath software platform. Multiple curve fitting algorithms and options allow you to fit even the most troublesome EIS data to one of the built-in equivalent circuit models, or alternately, you can design and draw your own equivalent circuit model.

• 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. Unique slider controls allow you to rapidly vary the value of one circuit component while watching the effect of that component on the Bode and Nyquist plots.

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.
