Description
SR N11-L PE snap ring cap is a blue N 11 closure fitted with a pierced septum of white silicone bonded to red PTFE. The septum is specified at 45° Shore A hardness and 1,0 mm thickness, giving a reliable reseal profile for routine chromatography and sample-handling workflows that use snap-ring vials. Designed for N 11 neck finishes, the polyethylene cap body provides a secure snap fit while the silicone/PTFE laminate offers chemical resistance on the sample side and mechanical resilience on the needle side. Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, these caps suit laboratories that standardise on 11 mm snap-ring systems for HPLC, GC or general analytical sample storage. The open-top design allows repeated septum penetration without removing the cap, supporting high-throughput autosampler use. Colour coding in blue aids quick visual identification on the bench or in storage racks. Dimensions and material combination match common N 11 PE snap-ring specifications, making the SR N11-L a practical consumable for method development, quality control and routine analysis where consistent septum performance is required.
