BASIC DESIGN
The Cheminert design involves a flat rotor which is engraved with slots to connect the
ports and a stator which is held against the rotor at a constant, preset force.
When repairs are required, just take out two or three screws, replace the rotor, and put
the screws back in and tighten them. No adjustments are possible, much less required.
Other advantages of the design include easy panel mounting, low actuating torque,
and compact size.
VICI Valves
A pioneer in products for HPLC, Valco continues to offer a diverse line in terms of number
of ports, fitting sizes, and materials of construction. 3, 4, 6, 8, 10, 12 port versions are
offered, with 1/32" (optional), 1/16", or 1/8" fittings. Valco valves offer a wide range of
rotor and body materials, with alloys and polymer composites capable of meeting virtually
any system requirement. However, longest lifetime is provided by ourCheminert coatedstator injectors.
All models can be ordered in manual, pneumatic, or electrically actuated versions.

TUBING
Overview
We offer chromatography grade tubing in ODs of 360 µm, 1/32", 1/16", and 1/8". Tubing
can be ordered in economical pre-cut standard lengths, or can be custom cut to meet your
specific instrumentation requirements. All VICI metal tubing is chromatographic grade
seamless drawn tubing of the highest available quality. Stainless tubing is 316 series.
Nickel-clad tubing – NEW!
•Fused silica, nickel-clad

The best qualities of silica-lined stainless but with improved heat transfer and a shorter
bend radius
•Polyimide-coated FS, nickel-clad

For ruggedized FS columns or transfer lines with robust metal ferrule connections
•PEEK, nickel-clad

Rated to 40,000 psi!
Electroformed nickel tubing
Unlike glass- or silica-lined stainless, ultra-smooth interiored EFNi can accept tight bends and
cutting without heating, and does not release damaging glass fragments or silica particles.

Product information
PEEK
•Natural PEEK
•Dual-layer PEEK


•Solid color PEEK
•Striped color PEEK
•Nickel-clad PEEK
Other polymeric tubing
Tubing is available in PTFE, FEP, and ETFE, in lengths of 10, 25, or 100 feet (or 5, 10, or 25

Product information
CUSTOM-BENT TUBING
We can supply tubing bent and formed to custom shapes. To learn more about our
custom tube bending service, contact VICI Precision Sampling. North American
customers may call toll-free (800) 828-1653.
CUSTOM PEEK TUBING
We now offer PEEK tubing custom- manufactured to meet your specific OD, ID, and
color requirements. The OD range is .014" (360 micron) to 1/8", with a minimum ID of
.002" for tubing up to 1/16" OD. (Maximum ID varies according to the OD.) Color
coding can be solid or striped.Contact us for more information.
