For all Cheminert C1, C2, C2V, and C3 type valves, VICI Jour offers our biocompatible PEEK sample loops 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 means no foreign materials will be introduced into the system. Softener-free polyethylene caps are used to protect the tubing from contamination. 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 of biological origin, 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.
Using tubing with a tighter ID tolerance will minimize the tolerance of the loop volume.
Tolerances: ±0.025 mm (.001")
