Description
Headspace vial N20-5 is a 5 mL brown roll-rim bottle with N 20 neck finish for headspace sample handling. Outer diameter is 20,5 mm and outer height is 38 mm, with a flat bottom and a flat DIN roll rim for standard crimp sealing. The brown glass body is suited to light-sensitive samples in chromatographic and general laboratory workflows that specify N 20 headspace vials. Nominal volume of 5 mL together with the compact 20,5 × 38 mm format supports routine headspace preparation where a flat-bottom DIN crimp-rim vial is required. Packaged as 100 pieces from manufacturer Macherey-Nagel, the vials fit organised bench and instrument supply for methods that call for N 20 roll-rim containers. Clear dimensional data—20,5 mm diameter and 38 mm height—aid rack compatibility checks and documentation. Select this brown N20-5 headspace vial when a 5 mL flat-bottom DIN roll-rim bottle at the stated outer dimensions is needed for laboratory sample work.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Vial N20-5, CR, a, 20.5x38, fl., DIN
What is this article?
Vial N20-5, CR, a, 20.5x38, 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.
