A novel column cartridge for a chromatography apparatus, particularly HPLC, is comprised of a hollow metal tube, open at both ends and having internal shoulders facing each open end, and a pair of end plugs each having a frusto-conical shape at its outer end. The end plugs are sealed into place by rolling the tube end to compress it against the frustum surface, leaving a short length of plug extending beyond the tube end for compression sealing against a conventional holder or mounting device.
