Description
Round-bottom flask with NS 29/32 is a standard laboratory vessel for preparative and analytical work that benefits from a spherical body and a defined ground joint. This variant offers a nominal capacity of 100 ml together with the widely used NS 29/32 joint, so it couples directly to matching condensers, still heads, adapters and stoppers in common glassware trains. The round geometry supports even heat transfer and efficient stirring when the flask is used with a suitable heating mantle, oil bath or magnetic stirrer setup. Pack size is 10 pieces, making the set practical for teaching labs, method development and routine parallel experiments. These flasks from manufacturer Dinkelberg belong to the laboratory materials category and are intended for general lab use where a reliable NS 29/32 connection is required. Country of origin is the Czech Republic. Consistent joint dimensions help maintain a stable seal under typical laboratory conditions with appropriate joint grease or sleeves. The 100 ml size suits small-scale reactions, distillations, solvent handling and sample work-up without occupying excessive bench or fume-hood space.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask with round bottom, with SJ 29/32, 100ml, 10/PK
What is this article?
Flask with round bottom, with SJ 29/32, 100ml, 10/PK is the article on this page. Luminix Health distributes Dinkelberg 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.
