These sample loops are made from PEEK tubing and fittings. Mechanically strong, chemically inert polymer ideal for HPLC applications. Softener-free polyethylene caps are used to avoid contamination of the tubing.

• Fits Valco W and UW type valves
• Tolerance of ±0,025 mm

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.
