Beschrijving
Vial N18-16 is a 16 mL clear glass screw-neck bottle with N 18 thread for laboratory sample collection, storage, and preparation. Outer diameter is 20,6 mm and height is 71 mm, combined with a flat bottom for secure standing on benches and in storage racks. The clear glass allows direct visual inspection of fill level, colour, and phase separation. Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, these screw-thread vials fit general sample-bottle and ampoule-related laboratory use where an N 18 closure interface is specified. The 20,6 × 71 mm geometry offers a practical mid-range volume without excessive footprint. Defined outer dimensions support consistent pairing with matching N 18 screw caps and related accessories. Suitable for quality-control aliquots, method development, and routine wet-chemistry workflows that require transparent sample vessels with a flat base and standardized screw neck.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Vial N18-16, SC, c, 20.6x71, flat
What is this article?
Vial N18-16, SC, c, 20.6x71, flat 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.
