ABSTRACT:
The present invention relates to a chromtographic column having a tube, preferably made of glass, with sealed-off connection pieces, preferably with frets, the tube having at each end flanges, which together with a screw joint, connect the connection pieces to the tube. The connection pieces have a central tube which possesses a clamping ring above the fret recess at its end. The clamping ring is preferably of conical design and the tube is surrounded by a sleeve which acts on the clamping ring through a counterpiece, preferably an oppositely sloped cone. Arranged between the clamping surfaces is a squeezable seal. The sleeve is supported by the screw joint and the tube has a thread passing through the screw joint and can be fixed by a nut on the upper part of the screw joint.
