Vial N20-20 is a 20 ml headspace crimp-neck vial (N 20) for laboratory sample handling and headspace workflows. Outer diameter is 22,5 mm and outer height is 75,5 mm, giving a compact clear-glass format with a flat bottom and a flat DIN roll rim. The glass-clear body supports straightforward visual checks of fill level and sample condition during preparation. Nominal volume is 0,02 l (20 ml). These vials are offered in a pack of 100 pieces from manufacturer Macherey-Nagel and suit routine headspace and analytical sample work where an N 20 DIN crimp finish is specified. The flat base stands stably on the bench or in trays, while the flat DIN roll rim is intended for matching N 20 crimp seals and caps. Clear, uncoloured glass keeps the vessel simple to inspect under standard laboratory lighting. Dimensions, rim style and pack presentation follow the stated N20-20 clear flat-bottom DIN configuration for consistent ordering and instrument compatibility in everyday lab use.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Vial N20-20, CR, c,22.5x75.5,fl DIN
What is this article?
Vial N20-20, CR, c,22.5x75.5,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 Labmateriaal.
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.
