Tubing
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.
Cutting and Cleaning
The improper cutting and cleaning of
metal tubing is the largest single cause
of chromatographic problems and
premature valve failure. The use of our
precision cut and finished tubing with
VICI fittings and valves maintains the
flow uniformity and cleanliness that
high performance systems require.
VICI’s electrolytic cutting process
yields polished tubing with flat
ends, minimizing the potential for
dead volumes or leaks caused by
the uneven ends and burrs left by
the tools common in the general
laboratory environment – wire cutters,
files, jewelers’ saws, and most tubing

Forty years of Valco

cutters. These non-precision cutters
are likely to generate particulates and
deform inner and outer diameters,
which can introduce dead volume and
flow anomalies.
Each piece of VICI pre-cut metal
tubing is specially cleaned with micro-
filtered steam from deionized water
to remove both organic and inorganic
contaminants, representing a major
improvement over the common
practice of using organic solvents to
“clean” tubing. Our test reports have
been confirmed by most of the major
instrument suppliers: the VICI process
provides analytically clean tubing.
