The EAS-2A Autosampler adopts a dual-stroke inner and outer dual-needle structure, where the outer metal needles open the septum and the inner PEEK needle pull the sample solution.This design prevents sample contamination, exhibits strong anti-interference capability, and ensures high accuracy. It is a high-precision, high-throughput scientific instrument.
