NKSSC-10-B 10 mm Black Open-Top PP Screw Cap With Red PTFE/White Silicone Septa (CAT#: STEM-AL-0143-ZJF)

This product is a 10 mm black polypropylene screw cap for GC and HPLC vial applications. It is configured as an open-top ND10 screw closure with a 7 mm center hole. The cap includes red PTFE/white silicone septa with 1 mm thickness. The open-top design supports needle access through the septa during autosampler sampling. The polypropylene cap body provides a practical closure format for compatible 10-425 vials. The septa help maintain sample containment while permitting controlled penetration. The cap is suitable for GC, HPLC, and routine analytical sample preparation workflows. This model is compatible with common autosampler platforms used in chromatography laboratories.
