Thermo Fisher, 6040.2325, Viper™ Fingertight Fitting Systems, Stainless Steel, 0.13 mm ID

Viper™ Fingertight Fitting Systems, Stainless Steel, 0.13 mm ID is designed for low-dead-volume tubing connections in analytical HPLC and UHPLC systems. This version is a stainless-steel capillary measuring 0.13 mm in internal diameter and 250 mm in length. Its ferrule-free fingertight connection enables an efficient, tool-free seal between compatible chromatography valves and columns without introducing substantial connection dead volume. The tubing is constructed of stainless steel and is rated for pressures up to approximately 1,300 bar, supporting high-pressure LC operations. The narrow 0.13 mm internal diameter can be selected when a method calls for a smaller tubing bore, while the 250 mm length provides a defined physical routing distance between fluidic components. The configuration can connect columns and valves from a broad range of LC manufacturers and is used for plumbing analytical chromatography systems rather than sample preparation or separation inside a packed column. Its flexible metal capillary and straightforward connection design are useful when setting up or maintaining liquid chromatography flow paths in confined instrument spaces.
