50 feet of our most popular solid red color PEEK Tubing.
Color-coding identifies the ID of your 1/16" OD PEEK tubing – each ID is coded with a different color.
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 nitric and sulfuric acid will attack PEEK.
Tolerance is ±.0005" for IDs up to .010", and ±.001" for larger IDs.
