Cytiva, 18111583, PEEK Tubing, 2 m, i.d. 1.0 mm, o.d. 1/16"

Cytiva PEEK chromatography tubing provides a polymeric flow-path connection between compatible liquid chromatography components. The tubing is supplied as a 2 m length with a 1.0 mm internal diameter and 1/16 in outside diameter. Polyether ether ketone (PEEK) is commonly used in liquid chromatography plumbing because it offers useful chemical resistance and avoids a metal wetted surface in selected fluid paths. The 1.0 mm bore has substantially greater internal volume than narrow analytical-LC capillaries, so it is appropriate only where extra-column dispersion and the method's pressure requirements remain acceptable. Cut tubing squarely using a suitable tool, select fittings designed for 1/16 in tubing, and check that the assembled connection is correctly seated. After installing, flush the line and verify flow, leakage and pressure performance with the operating solvent. Evaluate solvent compatibility rather than assuming that every organic solvent or strong reagent is suitable for PEEK.
