Description
Crimp cap ND20 Al headspace, colourless, is an aluminium sealing cap designed for headspace vials with an ND20 neck finish. The colourless finish supports clear visual identification of the sealed vial and suits routine sample preparation where neutral appearance is preferred. Supplied in a practical multipack of 10×100 pieces, the total pack delivers 1000 caps for continuous laboratory use. These crimp caps are intended for secure closure of headspace vials used in gas chromatography and related analytical workflows, helping maintain sample integrity during storage and transfer prior to analysis. The ND20 format matches standard headspace vial systems commonly found in pharmaceutical, environmental, and quality-control laboratories. Manufactured by Altmann Analytik, the caps form part of a focused range of laboratory sealing components for analytical sample handling. The aluminium construction provides a robust crimp seal when applied with a suitable crimping tool. Ideal for high-throughput environments that require consistent, colourless ND20 headspace closures in bulk packaging without unnecessary colour coding.

Questions about ND20 Al Headspace crimp seal, transparent, 1000/pac, 10 x 100 pc
What is this article?
ND20 Al Headspace crimp seal, transparent, 1000/pac, 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.
