FEP (fluorinated ethylene propylene) tubing is great for general, low pressure applications and is held to tight tolerances and has low gas permeability.
Much of our FEP Tubing—even the color-tinted options—is translucent, making it possible to watch fluid flow. Black FEP tubing is available for light-sensitive applications (such as enzymatic and chemiluminescent reactions) and entering/exiting flow cells.
Our 5' length PEEK tubing is rough cut to approximately 5'1". A trim cut should be made before use, we recomend a polymer tubing cutter.
