NKSSC-8-A-P 8-425 Black Pre-Slit Screw Cap With White PTFE/Red Silicone Septa (CAT#: STEM-AL-0193-ZJF)

This product is a black polypropylene 8-425 pre-slit screw cap for chromatography vials. It is configured with white PTFE/red silicone septa. The pre-slit septa format supports easier needle access during autosampler workflows. The ND8 screw closure is compatible with short or standard-opening 2 mL vial formats. The cap can be used with 2 mL glass vials, polypropylene vials, micro vials, and high recovery vials. It is suitable for GC, GC/MS, LC, LC/MS, and sample preparation applications. The cap is useful where a screw closure is preferred over snap or crimp formats. This model uses 1.5 mm thick septa with 45 Shore A hardness.
