PEEK Loops for Rheodyne® Valves
Part Number #JR-SLR-2190
For use with all Rheodyne® metal and metal-free valves, VICI Jour PEEK sample loops are available in a wide range of volumes. Tubing and fittings are made from PEEK, a mechanically strong, chemically inert polymer ideal for HPLC applications.
Our PEEK sample loops contain no metals or other extractable compounds, which prevents foreign materials from being introduced into the system. Softener-free polyethylene caps are used to avoid contamination of the tubing. PEEK hex-head nuts and PEEK ferrules provide reliable connections and prevent the tube from twisting.
PEEK sample loops are particularly well suited for separations involving proteins, peptides, nucleic acids, or other samples, as well as ion chromatography (IC) systems where metal traces may interact with ionic samples or release transition metals that deactivate ion exchange columns.
Other sample sizes are available on request. Please contact your distributor or VICI Jour directly.
TECH TIP
Using tubing with a tighter ID tolerance will minimize the tolerance of the loop volume.
