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
