NKSSC-18M-T UltraClean 18 mm Silver Magnetic Screw Cap With 1.5 mm PTFE/Silicone Septa (CAT#: STEM-AL-0100-ZJF)

This product is an 18 mm silver magnetic screw cap for GC and headspace analysis. It is fitted with UltraClean white PTFE/transparent blue silicone septa. The magnetic cap structure supports automated handling with compatible magnetic-picking autosamplers. The 1.5 mm thin septa support easier needle penetration and reduced fragmentation. The UltraClean septa configuration is intended for sensitive analytical workflows requiring low bleed performance. The screw closure design supports stable sealing on compatible precision screw headspace vials. The cap is compatible with 10 mL and 20 mL headspace vial formats. This model is suitable for headspace and SPME applications using CTC or Shimadzu autosampler platforms.
