Description
The N11-L aluminium crimp cap is a silver, holed closure for chromatography sample vials in the N 11 format. It combines a natural rubber/butyl septum in red-orange with a colourless TEF facing, hardness 45° Shore A and septum thickness 1,0 mm, for controlled sealing and needle access. The aluminium shell provides a durable crimp finish suited to routine analytical workflows. Packs of 100 pieces from manufacturer Macherey-Nagel support high-throughput vial preparation in GC and related laboratory methods. The laminated septum construction is intended to balance resealability with chemical contact performance at the TEF surface. Silver appearance aids visual distinction on the bench and in autosampler trays. Use with matching N 11 vials and appropriate crimping tools to achieve a consistent seal. These specifications make the cap a practical accessory where defined septum hardness, thickness and aluminium crimp geometry are required for N 11 chromatography closures.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about CC N11-H, si, NR/But or/TEF, 45°, 1.0
What is this article?
CC N11-H, si, NR/But or/TEF, 45°, 1.0 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
