PEEK Tubing



• 1/16", 1/8" and 1.8mm ODs Available
• Biocompatible, Inert and Easily Cut
• Great for High Pressure Applications

PEEK (polyetheretherketone) polymer tubing is biocompatible, chemically inert to most solvents, and can be used to replace stainless steel tubing in most liquid analytical systems. Unlike stainless steel and titanium tubing, PEEK tubing is flexible and can be easily cut to desired lengths. PEEK tubing can be used with stainless steel or polymer fittings.
The benefits of PEEK polymer tubing include a high pressure rating (up to 7,000 psi in most cases) and a high temperature rating (maximum continuous use temperature of 100ºC).
Additionally, PEEK tubing has a very smooth internal surface, which causes less turbulance than similar sized metal tubing.
Turbulence can cause remixing of separated sample bands and dilution of bands by the mobile phase. Of all our polymer tubing materials, PEEK is the least permeable to gas.
