EAS-2 Automatic Sampler
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.
Product Advantages
◆ Dual-stroke inner and outer dual-needle structure is compatible with septum protected corrosive sample.
◆ Enables unattended automated analysis, making it an essential option for batch analysis.
◆ Allows for adjustable sample volume to accommodate various sample types.
◆ The autosampler can be used with various brands of analytical instruments.
◆ Equipped with pre-wash needle and pre-sampling functions, reducing cross-contamination and minimizing waiting time between injections, thus achieving
high-throughput analysis.
