Description
Round-bottom flask with NS 45/40, 4000 ml is a large-capacity laboratory vessel for heating, reaction, distillation and evaporation tasks that require substantial working volume together with a wide standardised ground joint. The spherical four-litre body promotes uniform heat transfer and efficient mixing, while the NS 45/40 joint ensures compatible connection to condensers, adapters and other jointed glassware used in preparative and process-scale setups. Supplied as a pack of two pieces, this format is practical where fewer large vessels are needed rather than multi-piece packs of smaller flasks. The product comes from manufacturer Dinkelberg and is manufactured in the Czech Republic. Explicit joint size and capacity data support straightforward matching to heating mantles, oil baths, stands and existing NS 45/40 assemblies. Appropriate for synthetic chemistry, solvent recovery and laboratory operations that rely on robust round-bottom geometry and a generous four-litre working volume under controlled heating conditions.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask with round bottom, with SJ 45/40, 4000ml, 2/PK
What is this article?
Flask with round bottom, with SJ 45/40, 4000ml, 2/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.
