Beschreibung
Headspace crimp-neck vial N20-20 is a 20 mL clear glass roll-rim vial designed for headspace analysis, with an outer diameter of 22 mm and an outer height of 75 mm. The vial features a rounded bottom and a beveled crimp rim, together with a graduation mark at 15 mL for convenient volume reference during sample preparation. Packaged in units of 100 pieces, these N 20 vials support reliable sealing and handling in gas chromatography headspace workflows. Clear glass construction allows easy visual inspection of contents throughout the analytical process. This headspace format from manufacturer Macherey-Nagel is widely used in analytical laboratories for the determination of volatile organic compounds and related applications that require controlled equilibration. The beveled roll rim promotes a secure fit with matching crimp caps, while the rounded base aids uniform heating in headspace ovens and autosamplers. The standardised 22 × 75 mm profile ensures compatibility with common trays and heating blocks. Laboratories value the combination of optical clarity, defined geometry and the practical 15 mL graduation for routine and research headspace methods.

Questions about Vial N20-20, CR, c, 22x75, r, HS, GR
What is this article?
Vial N20-20, CR, c, 22x75, r, HS, GR is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Sample vials & NMR tubes, inside Tubes & vials, in Laborbedarf.
A sample vial is a small closed bottle for keeping or for presenting a sample. An NMR tube is a precision glass tube: the wall has to be straight and the diameter has to match the probe, or the spectrum contains the tube.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
