Fingertight zero-dead volume fittings
Looking to make perfect LC connections without any extra tools? Use Thermo Scientific Viper and nanoViper Fingertight Fittings throughout the entire fluidic pathway of your LC system.
Viper and nanoViper connections allow you to quickly connect LC modules, valves, and columns for leak-free connections that improve chromatographic results by minimizing dead volume. Viper and nanoViper fittings require no tools for installation, and combine simplicity with high performance.
Featured Viper fingertight fittings
Viper UHPLC fittings
Viper fingertight 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.
Reusable and available in stainless steel (SST), PEEK and a biocompatible alloy (MP35N).
