WaveNow USB Potentiostat / Galvanostat

Transcription

1 WaveNow USB Potentiostat / Galvanostat Detailed Description Pine Research Instrumentation is pleased to introduce our new line of portable USB potentiostats. Our WaveNow Potentiostat systems break with the past, replacing traditional stationary benchtop instruments with lightweight, portable and powerful alternatives. Weighing less than 200 grams, the WaveNow potentiostat system features a convenient USB interface, a fully functional potentiostat and galvanostat, and our powerful AfterMath instrument control and data analysis software. Portable. Only 30 mm thick and less than 175 mm long, the WaveNow potentiostat is the ultimate portable instrument. Small enough to fit into your laptop's tote bag, your carry-on luggage, or your coat pocket, the WaveNow lets you take your potentiostat to your work area rather than having to move your work area to your potentiostat. A universal AC power supply adapter ships with each WaveNow potentiostat, including adapters to fit standard US, EU, UK, and Australian power plugs. Affordable. At a fraction of the cost of other potentiostat systems, the WaveNow gives you exactly what you need without breaking your budget. The system is affordable enough that you can easily purchase two of them at the same time. And if you are outfitting your entire lab with potentiostats, please be sure to contact us for a special quantity discount quote. Capable. Designed with the everyday user in mind, the specifications for the WaveNow potentiostat are broad enough to permit you to perform a wide range of routine electrochemical techniques but also prudently chosen to allow for a simple and affordable design. Popular and common techniques such as cyclic voltammetry, bulk electrolysis, differential pulse voltammetry, square-wave and pulse voltammetry, chronoamperometry, and chronopotentiometry are easily configured and executed using our AfterMath TM software package.

2 A Note Regarding Potentiostat Specifications* The WaveNow potentiostat / galvanostat is designed to be an affordable, portable instrument capable of performing a wide array of electroanalytical techniques. The intended audience for this instrument are those researchers, instructors, and students who use electroanalytical chemistry as a routine tool. While many potentiostat designs feature such impressive specifications as extreme speed, extreme voltages, and over ten orders of magnitude of current measurement ranges, the reality is that even the everyday electrochemist rarely uses these capabilities. So, if you are just an everyday researcher searching for a powerful and portable potentiostat that fits into your budget as easily as it does into your carry-on baggage, then we think you'll enjoy owning a WaveNow potentiostat system.

4 AfterMath TM Scientific Data Analysis Software Our powerful AfterMath scientific data analysis software lets you create high quality graphs and reports from your experimental results. A licensed copy of AfterMath is included with each potentiostat that you purchase from Pine Research Instrumentation. AfterMath provides you with several important benefits. Instrument Control. When started, AfterMath automatically detects all compatible instrumentation attached to your computer and gives you complete control over each instrument. You can connect to one, two, or as many different attached instruments as you wish. You can queue up multiple experiments on one or more instruments, and while they are running, you can simultaneously work with data already acquired in previous experiments. Flexible Plotting. AfterMath has a powerful "drag-n-drop" feature that lets you easily take traces from one plot and simply drag them on to another plot. Making an overlay plot from several voltammograms is a snap. AfterMath gives you precise control over line sizes, point markers, colors, axis limits, axis labels, and tick marks. You can place one or more text boxes anywhere on the plot, and the text may be formatted with any combination of fonts, font sizes, colors that you wish.

5 Scientific Units. Unlike graphing applications designed for the business and marketing crowd, AfterMath is designed with scientific data in mind. Proper management of scientific units, metric prefixes, scientific notation, and significant figures is built right into the very DNA of Aftermath. If you divide a potential measured in millivolts by a current measured in nanoamps, then Aftermath properly gives you the result as a resistance measured in megaohms. Tools and Transforms. Flexible tools can be placed on any graph to precisely measure quantities like peak height and peak area. Multiple tools can be placed on a plot, and all such tools remain exactly where you leave them, even if you save and reload your data from disk. Several fundamental mathematical operations (addition, multiplication, integration, logarithm, etc.) can be applied to any trace on any plot. Data Archiving. Our unique and open XML-based file format allows you to keep data from several related experiments together in one single archive file. With AfterMath, you won't have to go hunting all over your hard drive to find all of your voltammograms. The internal archive hierarchy can contain as many subfolders, reports, plots, notes, experimental parameters, and data sets as you wish. Tel: 02) Fax: 02) sales@wonatech.com Web site:
