Description
ND20/ND18 20 ml headspace vial is a clear glass laboratory vial for headspace sampling and related chromatographic workflows. With external dimensions of 75,5 × 23 mm and an ND20/ND18 neck finish, it fits common headspace closures and instrument racks used in gas chromatography sample preparation. The rounded base improves stability during tempering and increases resistance to elevated internal pressure; the same geometry also helps the vial slide more smoothly into a heating block when it is introduced by magnet. Packaged as 10 × 100 pieces (1000 pieces in total), the multipack supports routine and high-throughput analytical work. This clear glass headspace vial from manufacturer Altmann Analytik is offered as an alternative to selected references including Agilent 5183-4474, Waters PSL408067, Chromacol 22-CV / 125, National Scientific C4020-2 / 100, Wheaton 985688, Finneran 320020A-2375 and VWR 548-0055. It is intended for laboratories that need consistent vial geometry, reliable sealing interfaces and convenient bulk packaging for volatile-sample analysis.
This article is part of Autosampler vials, in Vials, caps & septa.

Questions about ND20/ND18 20ml Headspace-Vial, 75,5x23mm, clear, rounded bottom, 10 x 100 pc
What is this article?
ND20/ND18 20ml Headspace-Vial, 75,5x23mm, clear, rounded bottom, 10 x 100 pc is the article on this page. Luminix Health distributes Altmann Analytik for laboratory use. It sits in Autosampler vials, inside Vials, caps & septa, in Chromatography equipment.
An autosampler vial is sized for the tray it will sit in. Neck finish, volume, clear or amber glass, and whether an insert is needed are the choices. Amber is for light-sensitive samples. A 2 mL vial is the ordinary one. A vial from a different neck standard takes a different cap.
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.
