Abstract:
A sanitary static seal for the fixed end of a chromatography column is described. The seal is in the form of an “L” or a “U” so as to form a seal against at least one major surface of the frit or screens and the outer peripheral edge of the frit or screen. In this way, any bypass is prevented and the potential for dead spaces such as O-ring grooves is eliminated thereby reducing the potential for bacteria or mold growth in the system. The gasket maybe formed separately and placed on the edge of the frit or screen or it may be molded in place.
