This component provides a precise seal between the injection needle and the flow path, ensuring accurate, leak-free sample introduction and consistent injection performance.
Constructed from Vespel®, a high-performance polyimide material, it offers excellent thermal and chemical resistance even under demanding HPLC conditions. The 0.12 mm ID capillary minimizes dead volume and supports accurate, reproducible sample delivery. Regular replacement of the needle seat helps maintain autosampler reliability and prevent sample carryover.
