Description
Vial N20-20 is a 20 mL headspace roll-rim bottle with N 20 neck finish for headspace sampling and related gas-chromatography workflows. Outer diameter is 23,25 mm and outer height is 75,5 mm; the amber body has a flat bottom and a flat DIN roll rim for crimp or roll-seal closures. The 20 mL nominal volume supports standard headspace methods where vapour-phase equilibration above the liquid or solid sample is required. Amber colouring helps protect light-sensitive contents during storage and analysis. Packaged in units of 100 pieces from manufacturer Macherey-Nagel, these DIN roll-rim vials are suited to routine headspace GC sample series and laboratory sample logistics. Dimensions of 23,25×75,5 mm and the flat-bottom profile aid stable standing on benches and in sample trays. Choose this N20-20 amber headspace vial when a flat DIN roll rim, 20 mL capacity and consistent outer geometry are specified for your autosampler or manual headspace protocol.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Vial N20-20, CR, a, 23.25x75.5, fl., DIN
What is this article?
Vial N20-20, CR, a, 23.25x75.5, fl., DIN is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Labware.
A flat-bottom flask stands on the bench without a cork ring, which a round-bottom flask will not do. It is for heating on a plate and for simple setups. It is a poorer shape than a round bottom for even boiling under vacuum.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
