PEEK-lined stainless steel tubing

Biotech AB proudly announces the new PEEK Lined Stainless Steel (PLS) Tubing from IDEX Health and Science, 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).

Wide Assortment of ID:s Available

At the heart of PLS Tubing is specially-extruded Upchurch Scientific® PEEK tubing in a wide assortment of inner diameters, ranging from 25 μm ID to 254 μm ID.

Designed to Work with VHP Fittings

PLS Tubing achieves its maximum performance of 15,000 psi (1,034 bar) when used with Upchurch Scientific VHP Fittings. The standard configuration of this tubing automatically pairs a length of tubing with two VHP-325 fittings, which allow repeat connections at UHPLC pressures. PLS Tubing is also available without fittings to allow the tubing to be paired with different polymer-based fittings; however, the use of other fittings may reduce the overall performance capabilities of PLS Tubing. Please contact us for more information and guidelines on proper use of the tubing.

Available in a Variety of Lengths

To accommodate the various connections that are required in the “high pressure” zone of today’s UHPLC systems, PLS Tubing will be available in a number of “off-the-shelf” lengths. (Custom lengths of PLS Tubing are also available, contact us for more information.)

Strong Yet Flexible

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.
