Description
BM N20-L bimetal crimp cap is an N 20 chromatography closure finished in blue and silver with a centre hole for needle access. It is intended for use with compatible sample or headspace vials in gas and liquid chromatography workflows where a reliable crimp seal is required during sample preparation, storage and injection. The bimetal construction supports a firm crimp that helps maintain vial integrity under routine laboratory handling and autosampler use. Supplied as a pack of 100 pieces, the closure is practical for continuous analytical throughput in research, quality-control and industrial laboratories. Net weight of the pack is 0,09 kg, which simplifies inventory and goods-receipt checks. This accessory forms part of the chromatography consumables range from manufacturer Macherey-Nagel and matches standard N 20 neck finishes used with manual or automated crimping tools. Laboratories choosing open-centre N 20 bimetal crimp caps gain consistent geometry for reproducible sealing across batches without an integrated septum in this configuration. Suitable as a dedicated spare or bulk consumable for systems that rely on centre-hole crimp closures.

Questions about BM N20-H, si/bl
What is this article?
BM N20-H, si/bl 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.
