nanovolume fittings

Nanovolume® connectors
for high resolution capillary HPLC


Select to jump directly to product numbers:


Cheminert nanovolume connectors include our new one-piece 1/32" fingertight fittings, with a patented* collapsible ferrule that makes fingertight nanovolume connections a snap. These fittings work with a variety of tubing, including PEEK, fused silica, and 1/32" electroformed nickel tubing (standard or gold-plated ID). Liners adapt the fittings for use with fused silica.

To avoid potential confusion, all fittings utilizing the Cheminert collapsible ferrule are made of black PEEK; fittings with a standard Valco ZDV fitting detail are natural PEEK.

* Patents pending
