Introduction
Rodeostat Introduction
The Rodeostat is an open source (hardware and software) potentiostat which is ready-to-use with firmware/software implementing many standard voltammetric methods. One of the main development goals was to make it easy for users to make custom modifications. To enable this the Rodeostat design is base…

Irreversible Cyclic Voltammetry
In this blog post we provide data from our testing of the new Rodeostat. We performed a side-by-side comparison between the Rodeostat and the Cheapstat potentiostat using ascorbate cyclic voltammetry experiments.

Reversible Cyclic Voltammetry
In this blog post we carried out a cyclic voltammetry experiment with ruthenium hexamine Ru(NH3)6 a reversible redox couple.

Electrochemistry: Current dependence on scan rate
In this tutorial we use the Rodeostat potentiostat and a screen printed electrode to demonstrate current dependence on scan rate. We know that for freely-diffusible analytes like ascorbate, the anodic peak current depends linearly on the square root of the scan rate. This is described by the Randles…
