Description
Headspace vial N20-5 is a 5 mL clear glass crimp-neck (roll-rim) bottle designed for headspace sampling and related analytical workflows. With an outer diameter of 20,5 mm and an outer height of 38 mm, the vial features a flat bottom and a flat DIN roll rim (N 20) for reliable sealing with matching crimp caps. The clear glass body supports visual sample inspection while maintaining dimensional consistency for automated or manual handling. Nominal volume is 5 mL (0,005 l). Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, these vials suit routine headspace GC sample preparation, storage of volatile matrices, and laboratory workflows that require standardised N 20 crimp geometry. The flat DIN roll rim promotes even cap seating, and the compact 20,5 × 38 mm format fits common headspace racks and trays. Ideal for analytical chemistry, quality control, and method development environments where reproducible vial dimensions and clear glass construction are essential.
This article is part of Flat-bottom flasks, in Beakers & flasks.

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