Abstract

A chromatography column comprises a tubular member (1) having an open inlet end and an outlet end and being adapted to receive a packing material, and an end piece (2) inserted through the inlet end of the tubular member (1). The end piece (2) comprises a generally planar inner end portion 4, and a rounded outer end portion (5), adapted to accommodate pressure forces acting on the inner end. The end piece (2) is fixed to the inner surface of the tubular member (1) by a weld- or bond-forming joining technique based on non-contact energy transfer, preferably laser welding. A method for manufacturing a pre-packed chromatography column is also disclosed.
