Abstract
A connector for the joining together two fused silica or glass or other types of capillary tubes, in a chromatography system, without detrimental chromatographic effects created by distortion of the two joined capillary tubes, dead volumes or exposure to metal surfaces, or for the butt joining of glass rods, has a pliable elongate surrounding member which sealingly engages a substantial length of each tube or rod from its end as well as supports each and thereby eliminates exposure to a housing or container surface.
