Microvolume Connectors - Replacement Components

microvolume replacement components

Inserts are made of stainless steel, Hastelloy C, Titanium, PEEK, or CTFE. PEEK rings are not usable above 75°C. The stainless steel ring with a metal insert can operate at up to 10,000 psi for HPLC or SFC.

We recommend that replacement ferrules be the same material as the insert, and replacement nuts be the same as the ring. All standard Valco zero dead volume nuts and reducing ferrules (ZRF, FS, and FSR) will work in these fittings.

TECH TIP

Valco microvolume fittings make it possible to couple 100 micron ID capillary GC, HPLC, or CZE columns without special nuts and ferrules. A stainless ring with one of the plastic inserts provides electrical insulation within the insert, while the PEEK ring achieves total isolation.
