Seals for GC, LC and HPLC
West manufactures lines seals for gas, liquid and high-performance liquid chromatography applications.

The seals are available in 8mm and 11mm diameter with polytetrafluoroethylene (PTFE) or ethylene-tetrafluoroethylene (ETFE) laminated rubber discs.

The lamination prevents interaction between the rubber disc and the sample and provides excellent self-sealing properties between sampling stages.
