Abstract
The present invention relates to a pre-packed chromatography cartridge (10) suitable for flash chromatography. The chromatography cartridge (10) comprises a barrel (20) having one end sealed with a cap (40), a thread (23) arranged on the outer cylindrical surface of the barrel (20) and engaged to a mating thread (43) on the inner cylindrical surface of the cap (40). The barrel is provided with at least one protrusion (24) arranged on the outer cylindrical surface and below the thread (23) in the direction from the end sealed by the cap (40). The protrusion (24) extends essentially radially outwards from the outer cylindrical surface of the barrel (20). The cap (40) is provided with a cylindrical flange (44) arranged below the thread (43) of the cap (40). A locking member (46) is arranged on the flange (44) and extends essentially radially inwards from the inner cylindrical surface of the flange (44). Together with the protrusion (24) of the barrel (20), the locking member (46) forms a mechanical connection that secures the cap (40) such that it cannot be unscrewed from the barrel (20).
