MicroTight® connectors

Product / Chromatography

MicroTight® unions, tees, crosses and adapters for capillary connections, plus a NanoTight™ union for 1/16" OD tubing sleeves, joining 360 µm, 1/32" or various capillary dimensions. A conductive MicroTight® union is available for introducing voltage into electrospray or capillary electrophoresis systems. Port designs include 6-32 and M4x0.7 internal coned and 5/16-24 external coned ports; pressure ratings range from 4,000 psi (276 bar) for some PEEK connectors up to 30,000 psi (2,070 bar) for VHP stainless-steel connectors.
