Open source hardware science instruments for research & education

Purposefully designed to be open, affordable, customizable & easy-to-use. Supported by documentation.

Electrochemistry & Biochemistry Tools

Currently we have two signature open hardware tools: the Rodeostat and Open Colorimeter. 

The Rodeostat is an open source potentiostat used in electrochemistry experiments. The Rodeostat has been used in many peer-reviewed publications covering a wide-range of studies such as novel biosensor research. In addition the Rodeostat is used as an educational tool for introductory electrochemistry labs. 

We also have a multi-channel version, the Rodeostat Plus, and a $20 Rodeostat Featherwing, an affordable and flexible version with many of the same capabilities as the original Rodeostat. 

The Open Colorimeter is an open hardware science instrument for researchers, educators and hobbyists. It is used with colorimetric assays for environmental studies, water-quality monitoring, biochemistry and more.
