WaveDriver 100/WaveVortex 10 RDE (E5TQ)

The WaveDriver® 100 EIS Potentiostat/Galvanostat has been engineered to provide you with the essential hardware and software features you need at an affordable price. A complete electrochemical workstation, the WaveDriver 100 lets you perform a wide variety of common DC electroanalytical techniques as well as Electrochemical Impedance Spectroscopy (EIS). The WaveDriver 100 finds use across a wide variety of applications, offering 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, iR compensation, and EIS frequencies 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. Some of the unique features to our approach to EIS analysis are summarized below:

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 100 bipotentiostat even more powerful?
Combining it with a precision electrode rotator manufactured by Pine Research…

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. If you are contemplating future RRDE research, then be sure to choose one of our WaveDriver 200 bipotentiostat/galvanostat bundles instead of a WaveDriver 100 bundle.
