IDEX Health & Science seamless, precut stainless steel tubing is
designed to meet the exacting requirements of today’s analyses.
We machine cut and polish each end, deburr the inside and
outside edges and passivate the tubing (please see the passivation
information box on this page). Finally, we flush reagent-grade
isopropanol through each piece.
Our thorough preparation and cleaning procedure guarantees tubing
that is truly ready-to-use, with fat, burr-free ends and a clean fnish.
This care is important in achieving zero-dead-volume connections and
good chromatographic results.
We offer a variety of precut lengths as well as longer lengths (5’ and 25’)
of some sizes. Cutting the tubing disturbs and roughens the tubing’s
end surface, so we recommend using our precut tubing whenever
possible. If you need to cut tubing to custom lengths, we suggest
you then passivate the tubing. For a description of a cold passivation
process, please contact IDEX Health & Science or visit our website at
www.idex-hs.com and search for “stainless steel tubing.”

High Pressure Tubing
Stainless steel is naturally self-passivating, forming an oxidized layer
on newly created surfaces. IDEX Health & Science takes extra steps to
ensure the chemical resistance of our stainless steel tubing by manually
passivating before and after the tubing is cut into specifed lengths
(except in a few cases where size is prohibitive). In the precut stage,
the internal wall is acid passivated and fushed. After the tubing is cut,
deburred and polished, it is completely submerged in an acid passivation
bath and again fushed clean. The table below summarizes the manual
passivation steps performed for each size of our stainless steel tubing:

polymer tubing can be used to replace stainless steel tubing
in most liquid analytical systems. Unlike stainless steel tubing, PEEK
tubing is biocompatible, fexible and can easily be cut to desired lengths.

Note
Our 1/32” OD tubing is designed for plumbing the Agilent 1100
Capillary LC system.
Standard 1/16” and 1/8” OD stainless steel tubing is suited for most
analytical applications.
