nanoViper fitting

Dionex has introduced the nanoViper fitting, a 100 MPa compatible, finger-tight fitting to be used with nano LC systems and nano and capillary columns.

The fitting does not rely on ferrules or ferrule-shaped parts to tighten to high- and ultra-high-pressure instruments. It provides correct fitting for each use, ensures zero dead-volume connections and fits any common column hardware or injection/switching valve platform.

The fitting is designed to prevent capillaries from slipping away from the column inlet even under ultra-high pressures, ensuring long-term, robust and zero-dead-volume operation. It is claimed to reconnect easily between different column hardware and features an integrated, removable tool to tighten without force and is suitable for small spaces such as the connections of a 10-port valve, once the integrated tool is removed.
