ABSTRACT:
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.
