Description
The N 20 aluminium crimp cap in silver with hole is a chromatography vial closure for secure sealing of larger neck sample vials. Fabricated from aluminium, this open-top Bördelkappe (crimp cap) is designed for use with suitable septa so that needles can access the sample while the cap remains crimped in place. The silver finish provides a clear, neutral appearance for routine laboratory identification. Delivered in packs of 100 pieces from manufacturer Macherey-Nagel, these N 20-L caps support standard N 20 vial formats common in headspace, GC and related chromatographic applications. They form part of core chromatography accessories for sample preparation, storage and autosampler workflows. Net weight per pack is 0,04 kg. Choose this open-hole aluminium crimp design when reliable mechanical sealing and repeated needle access are required without removing the entire closure. Suitable for analytical laboratories that standardise on N 20 crimp-neck vials for consistent sealing performance across series of samples.

Questions about CC N20-H, si
What is this article?
CC N20-H, si 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.
