PEEK Tubing
I
ts strength and inertness make PEEK (Poly Ether Ether Ketone) the obvious substitute for stainless steel when biocompatibility is
an issue. SIS offers two types of PEEK tubing: Solid color coded tubing, and natural tan tubing with a color coded stripe. The
striped material is recommended for maximum chemical resistance and biocompatibility, as the dye used for the stripe never comes
in contact with the fluid stream. PEEK is very chemically resistant, and can withstand halide salts and buffers of high ionic strength which
can degrade stainless steel. PEEK does not contribute metal ions or provide protein binding sites the way stainless steel can. Certain
organic solvents including Methylene Chloride, DMSO, and THF will cause PEEK to swell and will result in lower burst pressure.
Concentrated nitric and sulfuric acids will attack the polymer, although 30% nitric acid may be used for passivating.

T
he VICI Jour in-line filter traps fine and other particulates
from samples and mobile phases before they can dam-
age valuable instruments and columns. The PEEK body
and Ti encased filter elements give complete biocompatibility and
chemical resistance. In addition, the design has virtually no hold-up
volume, so these filters can be used in analytical applications with
virtually no band broadening or loss of efficiency.

Last Drop filter/sparger
The Last Drop filter/sparger combines filtration and sparging in a single unit. The PTFE housing con-
tains a mobile phase filter with either a stainless steel or a PTFE filter element. The filter/sparger features
a PEEK tripod connector for the solvent line, and a nut and ferrule for the sparging line. The filter element
is 2.5 µm; the sparger is 10 µm.
Biocompatible filters
This all PEEK filter can be placed in any 1/16" line, providing filtration to 0.5 microns. The filter
can be changed without tools, since both the filter housing and fittings are hand tightened.
Replacement elements are made of PEEK-encapsulated titanium.
