Sample Loops

PEEK Sample Loops avoid many of the problems associated with stainless steel sample loops. Metal loops will often absorb sample components resulting in inaccurate quantitative results. In addition, metal loops may be corroded by high-salt buffers and chloride salts. Sample Loops are made from PEEK tubing and fittings. PEEK (Poly-Ether-Ether-Ketone) is a mechanically strong, chemically inert polymer ideal for HPLC applications where metal surfaces may interact with mobile phase or sample components.

The PFA sample loop, 1.0 mm inner diameter, is used with the AXPRESS^® PLUS valve/pump module for oils applications.

The size designations of stainless steel loops are nominal. The actual volumes can differ from the theoretical designations because of the ± 0.025 mm (0.001") tolerance of the metal tubing bore.
