High pressure seal and coupling |
摘要 |
A coupling for high pressure liquid chromatographic columns of any length, individually, or by union of two columns together, in which an end fitting carries a secondary seal together with internal means for retaining the seal in place. The end fitting is designed as a unitary assembly wherein the secondary seal is secured into the end fitting as a unitary assembly of parts without the use of screw threaded members. A special screw and nut configuration of end fittings permits the same design to be used for columns of extremely short lengths.
