Description
MBK N20-L magnetic crimp cap is a silver N 20 closure with an 8 mm centre hole for laboratory sample vials that need a secure magnetic crimp seal. The open aperture supports standard septum arrangements used in chromatography, headspace work and other analytical workflows where needle access through the cap is required. Designed for N 20 neck finishes, the magnetic construction aids automated handling on systems that rely on magnetic transport or positioning of capped vials. Packs of 100 pieces from manufacturer Macherey-Nagel suit both method set-up and routine series work in sample preparation and instrumental analysis. The silver finish gives a clear visual identity on the bench and in autosampler trays, while the crimp geometry is intended to hold the septum firmly against the vial rim during sealing. These magnetic Bördel caps are a practical choice wherever consistent N 20 geometry, reliable needle passage and magnetic pickup are needed in everyday laboratory practice. Use with matching N 20 vials and suitable septa according to your method requirements.

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