A Bipotentiostat controls the voltage and measures the current at two Working Electrodes immersed in an electrolyte, using only one reference electrode and one counter electrode. It is generally used with an Rotating Ring-Disk Electrode for studies under flow conditions that can be precisely described mathematically. Rotating ring-disk electrodes are used where products generated at the disk electrode are monitored at the ring electrode. Rotating Electrodes are important research tools for fuel cell researchers, corrosion scientists, and anyone interested in controlling the mass transport of reactants to the electrode surface.
AFCBP1 bipotentiostat is a general purpose electrochemical instrument with a built-in analog voltage sweep generator. This can be operated as either a three or four electrode potentiostat for use in many kinds of electrochemical experiments, including cyclic voltammetry, anodic stripping voltammetry, rotating disk voltammetry, rotating ring-disk voltammetry and interdigitized array experiments. It can also be operated as a two-electrode device for tracing the current-voltage characteristics of electrochemical systems. One of the working electrodes can be operated in a galvanostatic manner where the current is controlled.
