Description
Crimp cap ND20 aluminium headspace with a 3,0 mm silicone white septum and silver aluminium foil is a colourless sealing component for headspace vials in analytical laboratories. The septum is fully coated with silver aluminium foil and remains temperature-resistant from −60 °C to 220 °C, supporting reliable closure during typical headspace workflows. Its ND20 aluminium shell is frequently used on PerkinElmer instruments and fits standard headspace vial necks for gas chromatography sample preparation. Offered in a pack of 1000 pieces from manufacturer Altmann Analytik, this configuration serves as an alternative to selected National Scientific and Wheaton references used in comparable applications. Soft silicone laminated with aluminium foil aids consistent needle penetration while the crimp design delivers a secure seal on ND20 headspace vials. Laboratories running multi-vendor instrument fleets can integrate this cap into routine analytical consumable sets without changing established vial formats or sealing practices.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about ND20 Al Headspace crimp seal,transparent, 3,0mm, 10 x 100 pc
What is this article?
ND20 Al Headspace crimp seal,transparent, 3,0mm, 10 x 100 pc is the article on this page. Luminix Health distributes Altmann Analytik 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.
