Beschrijving
Vial N20-5, RR is a clear 5 mL headspace crimp-neck glass vial with flat bottom for laboratory headspace and related sample work. The N 20 roll-rim design provides an outer diameter of 21,7 mm and an outer height of 38,2 mm, with a beveled crimp rim intended for compatible seals. Clear glass allows straightforward visual checks of contents, and the flat base supports stable standing on the bench or in racks. Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, these vials suit workflows that need a defined 5 mL nominal volume in a short headspace-style geometry. Consistent external dimensions support repeatable handling during preparation, sealing and transfer steps. Laboratories use this clear N20 flat-bottom headspace vial when a transparent glass container with roll rim and compact height is required for sample containment prior to analysis. The combination of 21,7 mm diameter, 38,2 mm height, flat bottom and beveled N 20 crimp rim offers a practical format for headspace-oriented and general analytical sample handling.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Vial N20-5, CR, c, 21.7x38.2,fl, HS
What is this article?
Vial N20-5, CR, c, 21.7x38.2,fl, HS 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.
