Striped color-coded 1/16" PEEK tubing

Precut and custom lengths

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 sulphuric acid will attack PEEK.

Color-coding identifies the ID of your PEEK tubing – each ID is coded with a different color. The stripe is added to the outside, so dye never contacts the fluid stream. Tolerance is ±.0005" for IDs up to .010", and ±.001" for larger IDs.

If you like the look of solid-colored tubing but have been concerned that a critical sample stream could be contaminated by the pigments used to color code the tubing, check out our new Dual Layer PEEK tubing. It looks like any other solid colored tubing at first glance, but a closer look reveals that the pigmented layer surrounds a separate but integrally-bonded inner layer of natural PEEK.

Custom PEEK tubing
Remember - we make custom PEEK tubing in any size and color, with an OD range of .014" (360 micron) to 1/8". Minimum ID is .002" for tubing up to 1/16" OD. (Maximum ID varies according to the OD.) The parts below represent only our stock items.
