Zero Dead Volume Fill Ports for 1/16" Cheminert and Valco Valves

fill ports for metal valves

The ZVISF-1 is a unique fill port designed to minimize sample carryover.

A leaktight seal is formed against the face of the bottom of the fitting detail instead of at the end of an angular ferrule, resulting in a true zero dead volume connection with no carry over or sample loss.

The polymer bushing snaps into the knurled PEEK nut, providing the convenience of a one-piece fitting. An ultrathin metal sleeve surrounds and supports the portion of the bushing which extends into the pilot of the fitting detail, preventing the bushing from mushrooming and getting stuck in the pilot as the fitting is tightened.

All fittings below are for use with a 22 gauge blunt tip needle.
