PEEK tubing has the strength required to withstand continuous use at HPLC
pressure without swelling or bursting. The dense polymer structure of VICI Jour
PEEK tubing eliminates the permeability to organic solvents that causes other
polymer tubing, such as ETFE, to "sweat".
VICI Jour tubing is color coded for easy identification of the ID. We recommend
"Striped Color-Coded" tubing. It is manufactured of virgin, natural PEEK and
therefore ensures maximum chemical resistance and biocompatibility. The color dye
is applied only to the outer surface and thus does not contact the fluid stream. "Solid
Color-Coded" tubing, however, is made of pre-dyed raw material.
The new VICI Jour striped premium grade PEEK tubing is the best choice for
chromatography applications in which exact flow rates or tube volume are important.
The tighter tolerance of ±0.025 mm ensures a more consistent internal volume of the
transfer lines.
PEEK tubing is not affected by halide salts, high strength buffers, or other
aggressive mobile phases that degrade stainless steel. The polymer surface will not
leach metal ions into the eluent or extract metal sensitive components from the
sample. By far the most outstanding property of PEEK tubing is its excellent burst
pressure.
PEEK is compatible with almost any of the solvents commonly used in HPLC.
However, dichloromethane, THF and DMSO may cause swelling in PEEK.
Concentrated nitric and sulphuric acid will attack PEEK.
