    摘要: A clamp for chromatography columns has a first seal with a first opening a movable seal with a second opening and a movable coupler. The movable coupler has first and second coupler seals with communicating third and fourth openings. The clamp is arranged for pressing a first chromatography column between the first seal and the first coupler seal and for pressing a second chromatography column between the movable seal and the second coupler seal, such that the first opening fluidly communicates with the second opening through the first chromatography column, the third and fourth openings and the second chromatography column.

    摘要: A connector unit for connecting capillaries, for high-performance liquid chromatography includes a connector capillary, a connector housing, and an annular sealing element. The connector capillary projects through a bore of the connector housing. The annular sealing element is provided on a front end region of the connector capillary and which is composed of a plastically and/or elastically deformable material. The connector capillary has an inner shell composed of a plastically and/or elastically deformable material and an outer shell which engages around the inner shell. The inner shell has a radially outwardly extending front end region which, on its own or together with the annular sealing element can generate a seal between the front end region of the connector capillary and a bushing unit.
