Potentiostats - well used

From an electronic point of view, potentiostats are operational amplifiers. Their special features, especially output power, speed, phase stability and extremely high input resistance are a real advantage for many applications beyond electrochemical ones.

The original purpose of a potentiostat is to control the potential between a working electrode WE and a reference electrode RE. Let us start this feature with the potentiostatic control as the regular use of a potentiostat.
