PEEK-lined stainless steel UHPLC tubing

A bioinert tubing with high pressure tolerance

PEEK-Lined Stainless Steel (PLS) Tubing from IDEX is ideal for biocompatible UHPLC applications. The tubing combines the strength of industry-standard 316 stainless steel with the chemical inertness of PEEK polymer to enable more efficient bio-separations at pressures up to 15,000 psi (1,034 bar).

At the heart of PLS Tubing is specially-extruded PEEK tubing in a wide assortment of inner diameters, ranging from 25 μm ID to 254 μm ID. The unique design features of PLS Tubing allow it to be bent into shapes that may be required by the system equipment, including angled bends and even sample loops for the injection valve, all with no loss of performance. Even in a bent shape, the PEEK lining maintains its integrity along the entire length. To accommodate the various connections that are required in today’s UHPLC systems, PLS Tubing is available in a number of pre-cut lengths, including 50, 100, 200, and 300 mm.

PEEK-Lined Stainless Steel (PLS) Tubing achieves its maximum performance of 15,000 psi (1,034 bar) when used with IDEX high pressure fittings systems, including MarvelXACT™, MarvelX™, and VHP fittings. Other fitting systems can also be used with the PLS tubing, however, this may reduce the overall pressure performance capabilities of PLS Tubing.
