Description
BM N20-L bimetal crimp cap with septum is an N 20 chromatography closure in blue and silver with a centre hole and a pre-assembled silicone blue transparent/PTFE colourless septum. The liner is specified at 45° Shore A hardness and 3,0 mm septum thickness, supporting controlled needle penetration and chemical resistance for typical GC and HPLC sample handling. Bimetal crimp construction helps secure the seal on compatible N 20 vials during preparation, storage and injection sequences. Offered in a pack of 100 pieces, the product suits high-throughput laboratories that standardise on N 20 headspace or sample vials. Net weight of the pack is 0,23 kg for straightforward stock control. This closure comes from manufacturer Macherey-Nagel and is aimed at chromatography accessories where a combined crimp cap and dual-layer septum is preferred. The blue transparent silicone face with colourless PTFE provides a practical sealing interface for routine analytical work. Ideal for research, quality-control and industrial environments that require consistent N 20 crimp geometry with defined septum hardness and thickness.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about BM N20-H, si/bl, Sil bltr/PTFE, 45°, 3.0
What is this article?
BM N20-H, si/bl, Sil bltr/PTFE, 45°, 3.0 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.
