The epsilon is a family of
potentiostat/galvanostats that has been designed to allow the user great flexibility in choosing their particular instrument. The most
basic epsilon instrument can be used for standard techniques listed above, as well as chronopotentiometry, making it ideal for the
teaching lab or for materials characterization (e.g., characterization of transition metal complexes by cyclic voltammetry and
controlled potential electrolysis, or of biosensors by cyclic voltammetry and constant potential amperometry). Pulse, square wave, and
stripping techniques can be added by a software upgrade, and a second channel can be added by a hardware upgrade.
