Thermo Fisher, 6040.2385, Viper™ Fingertight Fitting Systems, Stainless Steel, 0.18 mm ID

Viper™ Fingertight Fitting Systems, Stainless Steel, 0.18 mm ID is designed for tool-free fluidic connections in analytical liquid chromatography instruments. The selected configuration uses a stainless-steel capillary with a 0.18 mm internal diameter and a 250 mm length. A ferrule-free fingertight sealing system produces a virtually zero-dead-volume connection to compatible LC columns and valves, helping avoid unnecessary peak broadening at tubing junctions. The flexible stainless-steel capillary has a 1/32-inch outside diameter and is suitable for high-pressure HPLC and UHPLC fluid paths, with a maximum pressure of approximately 1,300 bar. Compatibility across a broad range of valve and column interfaces enables the component to be used for installation, maintenance, or reconfiguration of chromatography modules. Its 250 mm length supports shorter plumbing paths where adjacent connections do not require a longer capillary. The internal diameter should be considered when matching tubing to a chromatography method because tubing dimensions influence system extracolumn volume. The product is supplied as one connection component and is not a chromatographic separation column.
