New Universal UHPLC Fingertight Fitting Technology for UHPLC and HPLC

Dionex Corporation introduces Viper™, a 100 MPa compatible, patent-pending, stainless steel, fingertight fitting system to be used with UHPLC and HPLC systems.

This is the first commercial fitting system in the history of HPLC that does not rely on ferrules or ferrule shaped parts to tighten to high and ultra-high pressures. The new fitting system provides three important customer values: firstly, it guarantees a correct fitting each time it is used; secondly, it guarantees zero dead volume connections; and thirdly, it fits to any common column hardware or injection/switching valve platform in the HPLC market.

The Viper fittings are designed to prevent capillaries from slipping away from the column inlet even under ultra high pressures and thus guarantee long-term, robust, zero-dead-volume operation. Viper provides highest ease-of-use as it reconnects easily between different column hardware. It also features an integrated removable tool to tighten without force and it even fits spaces as small as the connections of a 10-port valve, once the integrated tool is removed.
