Agilent, 5067-5958, InfinityLab Quick Connect Fitting assembly with pre-fixed 0.12 x 150mm capillary

Agilent InfinityLab Quick Connect fitting assemblies create low-dead-volume connections at the inlet of high-performance and ultrahigh-performance liquid chromatography columns. A spring-loaded, finger-tight fitting is combined with a pre-fixed stainless-steel capillary having a 0.12 mm internal diameter and a 150 mm length. The assembly includes a Quick Connect end and a Swagelok connection at the opposite end. Pressure stability extends to 1300 bar when installed in a suitable LC configuration. The spring-loaded seal helps accommodate column changes without repeated manual adjustment of a conventional ferrule, limiting connection-related peak broadening and leakage. Before installation, verify that the capillary dimensions, end fittings and flow path match the instrument and column port. Establish solvent flow gradually, monitor the assembled connection for leaks, and inspect capillary routing to prevent sharp bends. Proper fitting installation protects chromatographic efficiency, especially in low-dispersion UHPLC systems.
