ABSTRACT:
A container for protecting and enclosing an electrophoretic support medium is disclosed. The container includes a first portion and a second portion slidingly engageable with one another, whereby when closed they sealingly engage one another to form a substantially air-tight cavity therein. The first portion has a first recess defined by a protruding rim for accommodating a portion of the support medium therein. The second portion has a second recess defined by a protruding rim for accommodating the remainder of the support medium therein. The protruding rims are spaced apart from the bottoms of each portion and engagable with the base sheet of the support medium, whereby the support medium is retained within the recesses between the rims and the bottoms. The bottoms each have a substantially smooth planar surface to facilitate secure retention of the support medium.
