Color-coding provides easy identification of the ID of your PEEK tubing – each ID is coded with a different color stripe. PEEK tubing has the strength required to withstand continuous use at HPLC pressure without swelling or bursting, and is not affected by halide salts, high-strength buffers, or other aggressive mobile phases that corrode stainless steel.
The polymer surface will not leach metal ions into the eluent or extract metal-sensitive components from the sample. However, PEEK can be somewhat absorptive of solvents and analytes, notably methylene chloride, DMSO, THF, which may cause swelling. High concentrations of sulfuric and nitric acid will attack PEEK.
Maximum recommended working temp: 100° C (continuous) for 1/16" OD tubing with ID ≤0.75 mm. The high-performance you expect from VICI Jour PEEK tubing, each ID coded with a different colored stripe for easy identification.
Options: Other package sizes and tubing lengths are available. Customized ODs and IDs are available (minimum quantity of 30 meters).

PEEK and Other Polymers
PEEK exhibits excellent resistance to a wide range of organic and inorganic chemicals. The compatibility of PEEK with many chemicals at 20°C (68°F) has been investigated and the results for unreinforced grades are given in the table below.
PEEK is compatible with almost any of the solvents used in HPLC. The only solvents which will attack PEEK are concentrated nitric acid and sulphuric acids. However, PEEK tubing can safely withstand the 20-30% nitric acid used for system passivation.
Methylene chloride, DMSO, and THF may cause swelling in PEEK. The highest temperature we recommend for PEEK is 100°C. Up to that temperature the tubing will maintain the stated pressure rating.

Use the chart below to determine the volume per length of tubing, based on the inside
dimension (ID). Note that VICI Jour 1/16" OD tubing typically has an ID
tolerance of ±.001". This is a much tighter tolerance than normal commercial grades of tubing; however, it is
enough to result in noticeable error if exact volumes are not measured.
