Natural PEEK Tubing

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. Note, however, that dichloromethane, THF, and DMSO may cause swelling in PEEK, and concentrated acids like nitric and sulphuric acid will attack PEEK. Available in ODs from 360 microns to 1/4", in custom lengths (priced per meter) and pre-cut lengths of 1.5, 3 and 10 meters.
