A container for protecting and enclosing an electrophoretic support medium is disclosed. The container includes a top portion and a bottom portion, which when closed sealingly engage one another to form a substantially air-tight cavity therein. The bottom portion has a recess formed therein for accommodating the support medium and at least a portion of the recess has a substantially smooth planar surface. The bottom recess is defined by a protruding continuous rim which has a plurality of nubs protruding into said recess and engagable with the base sheet of the support medium, whereby the support medium is retained within the recess.
