A potentiostat is an instrument designed to control the electrodes
in an electrochemical system
by adjusting the potential
and measuring the subsequent effect on current (or potential). This task is accomplished through a variety of internal circuits, operational amplifiers, and feedback loops. External cables are used to physically connect to each electrode, which typically includes a working electrode,
a counter electrode,
and a reference electrode.
A bipotentiostat is a special type of potentiostat that can control two distinct working electrodes simultaneously, along with a counter electrode and a reference electrode.
