Thermo Fisher, 6083.2300, 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 fluidic connections in analytical HPLC and UHPLC systems. This particular Viper stainless-steel capillary has a 0.13 mm internal diameter and a 300 mm length. The flexible stainless-steel tube has a 1/32-inch outer diameter and uses the Viper fingertight fitting design, which seals at the tubing tip rather than relying on a conventional ferrule position. The resulting connection minimizes unswept space that could otherwise contribute to chromatographic band broadening. Tool-free installation facilitates changes to columns or valve connections, and the fitting design is compatible with a wide range of chromatographic hardware. This capillary format supports system pressures up to approximately 1300 bar, with a Viper system capability stated to 1310 bar, and can be used at temperatures up to 120 °C within the applicable product limits. The 0.13 mm bore makes the capillary suitable for analytical-scale fluidic paths where internal volume is important. It is a connection component supplied individually, rather than a prepacked chromatographic column, detector or complete LC system. The 300 mm length distinguishes this part from shorter Viper variants with identical 0.13 mm internal diameter. Choosing the intended tubing length helps preserve the desired fluidic routing while limiting unnecessary connection volume. Stainless-steel capillary construction is distinct from polymer tubing and is intended for high-pressure analytical LC plumbing.
