ABSTRACT:
An electrophoresis device includes first and second electrode vessels for containing buffer solution and adapted to be connected to poles of a direct current source. A plurality of vertical channels containing carrier medium have opposite ends opening into the first and second electrode vessels. At least one of the electrode vessels has a cavity into which commonly open adjacent ends of the channels. A sealing piece is operable to seal in an airtight manner the cavity and thereby the ends of the channels from the interior of the electrode vessel. A connection extends through the sealing piece to the cavity to connect the cavity and the interiors of the channels to a source of overpressure or underpressure.
