A potentiostat is a wonderfully useful tool in the study of electrochemistry. However, their widespread adoption is limited primarily by their price, with research setups often costing up to $10,000 and barebone potentiostats still upwards of $1,000 (i.e. Dagan Chem-Clamp). A group out of UC Santa Barbara have developed both the hardware and software necessary to build your own potentiostat for only $80. Placing it well in the range of undergrad and developing world lab budgets.

To test it’s capabilities they also ran it through a few sample projects listed below.

• Measurements of Ascorbic Acid in Orange Juice   

• Monitoring Redox of Ferricyanide Using Cyclic Voltammetry 

•  Analysis of Acetaminophen Content in Over-the-Counter Pain Medication Using Linear Sweep Voltammetry 

•  Construction of a Simple E-DNA Biosensor and its Interrogation Using Square Wave Voltammetry
