Microbore UHPLC Injectors and Switching Valves

Nanovolume® UHPLC injector

Cheminert microbore UHPLC injectors and switching valves are ideal for high speed, high throughput techniques which demand a valve and fitting system that minimize internal volume and eliminate dead volume.

A proprietary rotor material and stator coating achieve pressures to 20,000 psi, suitable for the most demanding analytical techniques. All models are compatible with any VICI actuation option.

TECH TIP

The 20,000 psi 6 port valve with 1/16" fittings on this page was supplied as original equipment in EASY-nLC models prior to the Model 1200. Some users have experienced premature valve failure caused by overtightening the Viper™ fittings. We now offer a new stator design which virtually eliminates this possibility.
