CH627279

An apparatus for performing electrophoresis and a multiple-sample applicator for use therewith. Electrophoresis is a physical process in which electrically charged molecules and colloidal particles, upon the application of a DC current, migrate along a gel or a membrane that is wetted with an electrolyte. If a membrane is used, its middle section is kept in tension horizontally above an electrolyte tank, while the ends of the membrane hang down into the electrolyte. If a gel is used, it is held in a tray which is placed on a cooling plate, and wicks make contact with the electrolyte. The tank has unique protected electrodes for conducting the DC current.
