Any UHPLC can now easily be converted for Biocompatible applications with PEEK^® lined stainless steel tubing. IDEX Health & Science/Upchurch Scientific introduces PEEK-Lined Stainless Steel (PLS) Tubing for biocompatible UHPLC applications, complete with suitable VHP fittings.   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).

Strong yet flexible

The unique design features of PEEK lined stainless steel  tubing (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. At the heart of PLS Tubing is specially-extruded Upchurch Scientific® PEEK tubing in a wide assortment of inner diameters, ranging from 25?m ID to 254?m ID. To accommodate the various connections that are required for 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.  

Works with VHP Fittings for UHPLC

PLS Tubing achieves its maximum performance of 15,000 psi (1,034 bar) when used with the included 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.        

Other standard lengths (with above ID's) available are:

• 100mm
• 200mm
• 500mm
