Rodeostat: open source potentiostat

$ 200.00

New version 0.2

The Rodeostat  is an open source potentiostat for performing electrochemical measurements which is designed to work with the Teensy 3.2 development boardIt is a very flexible instrument with multiple output voltage and current measurement ranges. 

  • Current measurement ranges: +/- 1, 10, 100, 1000uA
  • Output voltage ranges: +/- 1, 2, 5, 10V

    The Rodeostat is sold with a clear acrylic enclosure and a pre-programmed Teensy 3.2. Also included are a USB cable, set of 3 alligator clip cables and a 50K dummy cell.

    New features available in version 0.2.

    • Adjustable ranges,  +/- 1, 2, 5, 10V, for reference electrode measurements
    • Digital switches for software control of electrode connections

    The Rodeostat firmware implements many common voltammetric methods e.g., chronoamperometry, linear sweep, cyclic and constant voltage voltammetry. The potentiostat is easily re-programmed with the popular Arduino IDE via the Teensyduino add-on. 

    Rodeostat Open Source Software

    1) Software is available in the form of a web-based application which provides a graphical user interface. A description and user guide can be found here:

    2) Software is also available in the form of a Python library which enables the users to configure and run voltammetric tests from a host PC. A getting started guide and documentation for the python library can be found here 


    Adapters for screen printed electrodes and additional dummy cell ranges are also available separately in the store.
