Description
N 20 headspace roll-neck vials with a nominal volume of 6 mL are intended for headspace gas chromatography and related sample equilibration work. Each clear glass vial measures 22 mm in outer diameter and 38,25 mm in outer height, with a rounded bottom and a bevelled roll rim for secure crimp sealing on N 20 closures. The transparent glass allows visual inspection of sample level and phase behaviour during preparation. A pack contains 100 pieces, supporting high-throughput laboratories that require uniform vial geometry for autosamplers and manual headspace systems. Manufactured by Macherey-Nagel, these vials combine a practical 6 mL working volume with standard N 20 neck dimensions for broad instrument compatibility. The rounded base aids even heating and mixing of the sample matrix, while the bevelled crimp rim promotes consistent cap seating. Suitable for routine VOC and residual-solvent headspace methods where clear glass and defined outer dimensions are preferred.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Vial N20-6, CR, c, 22x38.25, r, HS
What is this article?
Vial N20-6, CR, c, 22x38.25, r, HS is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
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.
