Duostat power supply

Description (Brief)
This power supply was used in the Stanley Cohen lab at Stanford University to run an electrical current through a vertical chamber for gel electrophoresis (see object 1987.0757.14). Gel electrophoresis was one of the most important tools Cohen and Boyer used to analyze the effects of restriction enzymes on plasmids. The technique allows a way to visualize molecules by separating them out according to their length using an electrical current.
