Description
neochrom® headspace vials, 20 ml, are clear-glass sample containers with roll finish, dimensions 75,5 x 23 mm and a rounded bottom for reliable headspace and autosampler workflows. Manufactured from glass of the first hydrolytic class, they offer the chemical resistance and dimensional consistency expected in routine GC sample preparation. The rounded base improves mechanical stability under elevated internal pressure during tempering and helps the vial slide smoothly into a heated block when magnetic transfer is used. A roll (crimp) finish supports standard headspace closures across a wide range of instruments. Market instruments demand many vial geometries; these clear 20 ml bottles address common volume, neck and base requirements without writing fields or fill marks. Supplied in packs of 100 pieces from manufacturer neolab - Labor, they suit laboratories that need transparent vessels for visual sample checks in autosampler trays and heating stations. Use them wherever clear first-hydrolytic-class headspace glassware with a rounded bottom and roll rim is specified for analytical sample handling.
This article is part of Autosampler vials, in Vials, caps & septa.

Questions about neochrom® Headspace Flaschen, 20 ml, Klarglas, Rollrand, 75,5 x 23 mm, gerundete
What is this article?
neochrom® Headspace Flaschen, 20 ml, Klarglas, Rollrand, 75,5 x 23 mm, gerundete is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Flacons pour passeur d'échantillons, inside Vials, bouchons & septa, in Chromatographie.
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.
