PEEKsil™ tubing

Product / Chromatography

PEEKsil™ tubing combines a fused silica capillary with a sheeting cover of PEEK polymer, making it mechanically strong with ideal characteristics for sealing with many fitting styles. The fused silica core provides a consistent, rigid fluid pathway with excellent chemical compatibility and very low adsorption, and it can replace stainless steel or PEEK tubing in many analytical systems. It should never be cut manually and is used at its precut lengths. Pressure tolerance varies from 6,000 psi (414 bar) to 25,000 psi (1,723 bar) depending on ID, and it can be used up to 100 °C.
