Abstract
A column for use in chromatography, the column having a tube with a bore that can contain a packing medium captured between two porous plugs positioned at opposite ends. End fittings are attached to the tube ends, the end fittings having a duct with a duct opening having a diameter at least as large as the diameter of the tube bore which it faces. The duct opening may be positioned within a recess in spaced apart relation to the porous plugs to prevent the end fitting from contacting the plug and burnishing its surface.
