PEEK Tubing

• 1/32", 1/16", 1/8", and 1/4" ODs
• Available premium grade tubing with tighter tolerances
• Easy to cut
• Biocompatible

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.
