Potentiostat VASD 40

Description The VASD40 is a potentiostat developed in collaboration with teachers in highereducation to provide a flexible educational approach for polarization curvemeasurements (current/potential). Its 3 x 4 mm bananaplugs allow connection of the 3 electrodes needed for such measurements: - A "working"electrode (W) where the reaction occurs with the electro-active chemicalspecies in the solution studied - A reference electrode(R) - An auxiliary electrode(A), also known as the counter-electrode. The potentiostat performs a voltammetricmeasurement, which involves applying a potential and measuring the resultingcurrent. For a given potential, the current will be proportional to theconcentration of the chemical species analysed.
