Description
N 11 aluminium crimp cap with hole is a red crimp closure fitted with a PTFE red/silicone white/PTFE red septum for secure sealing of N 11 vials in chromatography and analytical sample handling. The laminated septum is specified at 50° Shore A hardness with a septum thickness of 1,0 mm, supporting reliable needle penetration and resealing during injection workflows. Supplied in packs of 100 pieces, this aluminium Bördelkappe (crimp cap) suits routine GC and HPLC sample preparation where a defined open-top aluminium shell and multilayer PTFE–silicone–PTFE liner are required. The construction from manufacturer Macherey-Nagel combines a durable aluminium body with a chemically resistant liner stack intended for laboratory vial systems of the N 11 format. Colour coding in red aids quick visual identification on the bench or in autosampler trays. Use these holed crimp caps wherever standardised N 11 closures with a 1,0 mm PTFE/silicone/PTFE septum are specified for analytical sample integrity and reproducible sealing performance.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about CC N11-H, r, PTFEr/Sil w/PTFEr, 50° 1.0
What is this article?
CC N11-H, r, PTFEr/Sil w/PTFEr, 50° 1.0 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
