Description
Round-bottom flask 100 ml with narrow neck is a laboratory glass vessel intended for heating, distillation, reflux and collection applications. Manufactured from borosilicate glass 3.3, it features a single narrow neck and a beaded rim for secure handling and stopper fit. The nominal volume is 0,1 l, making the format suitable for small-scale preparative and analytical procedures. Packed ten pieces per carton from manufacturer Marienfeld, these flasks support efficient restocking of laboratory glassware sets. The round-bottom geometry promotes uniform contact with heating mantles and oil baths, while the narrow neck accommodates common laboratory stoppers and simple adapter connections. Typical uses include boiling of solvents, distillation setups and temporary collection of distillates or reaction mixtures. The clear glass wall allows visual monitoring of boiling behaviour, phase changes and residual volumes. Research groups, quality-control laboratories and educational facilities employ such flasks as transparent vessels for routine wet-chemistry workflows where borosilicate glass 3.3 is specified.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks with round bottom 100 ml, narrow neck
What is this article?
Boiling flasks with round bottom 100 ml, narrow neck is the article on this page. Luminix Health distributes Marienfeld 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.
