The Platinum-Coated SUS Needle Assembly (228-42325-01) is a high-precision replacement injection needle designed for Shimadzu SIL-series HPLC autosamplers. Manufactured from premium stainless steel and coated with a thin layer of platinum, the needle offers superior chemical inertness compared to conventional stainless-steel needles. The platinum coating minimizes adsorption of active compounds such as amines, acidic compounds, peptides, and chelating agents, significantly reducing sample carryover and improving injection repeatability. The precision-ground needle tip ensures smooth septum penetration while maintaining accurate sample aspiration and delivery during high-throughput chromatographic analysis.
