PEEK Loops for Cheminert valves

Cheminert PEEK loops
  • Fits all Cheminert C1, C2, C2V, and C3 type valves
  • Wide range of volumes available
  • Biocompatible

VICI Jour PEEK sample loops are made from PEEK tubing and fittings. PEEK is a mechanically strong, chemically inert polymer ideal for HPLC applications. Since our PEEK sample loops contain no metals or other extractable compounds, no foreign materials will be introduced into the system. Softener-free polyethylene caps are used to avoid contamination of the tubing.

PEEK sample loops are particularly well suited for separations involving proteins, peptides, nucleic acids or other samples of biological origin as well as in IC systems where metal traces may interact with ionic samples or release transition metals that may deactivate ion exchange columns.

loop fittings

PEEK hex-head nuts and PEEK ferrules provide reliable connections, and avoid twisting of the tube.
