A chromatography cartridge and method of manufacturing same. A
chromatography cartridge of the present invention can include a tubular
housing having an open end and an inner surface, and a plug. The plug can
be positioned within the open end of the tubular housing and can have an
outer circumferential surface, a substantial portion of the outer
circumferential surface being fused to the inner surface of the tubular
housing. A method for manufacturing a chromatography cartridge can
include coupling at least a portion of the outer surface of the plug to
at least a portion of the inner surface of the tubular housing in
response to rotating at least one of the plug and the tubular housing
about the longitudinal axis with respect to the other of the plug and the
tubular housing.
