A plug unit configured for use in high performance liquid chromatography is described. The plug unit comprises a capillary comprising a capillary distal face; a sealing element, wherein at least a portion of the sealing element is located distal from the capillary distal face; and a biasing element configured to bias the capillary towards the sealing element.

Plug units, particularly for HPLC, connection system and corresponding use

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.

Connector unit and connecting system for connecting capillaries, in particular for high-performance liquid chromatography

The invention relates to a connector unit for connecting capillaries, in particular for high-performance liquid chromatography, wherein a sealing element sealing the capillary protrudes at least partially into the interior of the capillary, while a portion of the sealing element that protrudes axially from the capillary can be subjected to a compressive force that is introduced via the capillary to obtain an axial or radial plastic and/or elastic deformation.
