Fingertight zero-dead volume HPLC fittings and kits
Thermo Scientific Viper and nanoViper HPLC fittings, connectors, tubing, and kits allow you to quickly connect HPLC modules, valves, and columns for leak-free connections that improve chromatographic results by minimizing dead volume. Viper and nanoViper fittings systems and kits require no tools for installation, fit narrow connections (e.g., 10-port valves), and combine simplicity with high performance.

HPLC and UHPLC fittings
Our HPLC and UHPLC fittings seal at the tip of the tubing, virtually eliminating dead volumes and making it easier to plumb your HPLC or UHPLC system without any tools for reproducible leak-free connections to pressures up to 1500 bar. The nanoViper HPLC fittings consist of PEEK-shielded fused silica tubing and a fingertight sealing fitting.
Our HPLC and UHPLC Fittings, Connections, Tubing, Crosses, Tees, and kits are reusable and available in stainless steel (SST), PEEK and a biocompatible alloy (MP35N). Find specific fittings and capillaries or purchase complete solution kits for your nano LC system or applications.
