Shimadzu Sil-20AHT Direct Injection Autosampler

The Shimadzu Sil-20AHT is a total-volume injection type autosampler.  It enables high-speed injection and high-throughput sample processing withoutwasting sample.  It is designed to ensure greater stability, with improveddurability attained through modifications in valves and sample loops.  Multiplevial and plate types are supported, and a control vial rack isolates standardsfrom analytical samples.
