tech tip
When using Cheminert
Nanovolume® CN2
injectors and valves,
use fill ports designed
just for them.
Nanovolume
fill ports . . . . page 60
Fill ports
for 1/16" polymeric Cheminert valves
These fill ports provide direct syringe connections to polymeric valves and fittings. Since the fitting
detail in the high pressure Cheminert valve is unique, be sure to order the high pressure version for
polymeric HPLC injectors. For use with 22 gauge blunt tip needle.

Fill ports
for metal Valco and Cheminert valves
Fill ports provide direct syringe connections to valves and fittings, with the
polymeric ferrule compressing a liner to seal around the needle. These fill ports
are for use with metal valves.

Zero dead volume fill ports
The ZVISF-1 is a unique fill port fitting designed so that 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.
For use with 22 gauge blunt tip needle.
