Low cost potentiostat: Criteria and considerations for its design and construction

This article shows the construction of an inexpensive potentiostat, considerations and criteria to be taken for manufacturing it. General purpose and low cost electronic devices were used in this proposal. Excellent results for square wave voltammetry (cyclic voltammetry) were gotten against a commercial potentiostat, this technique is basic and very widely used in the field of electrochemistry.
