Description
Round-bottom flask with NS 29/32, 2000 ml is a classic laboratory vessel for heating, reaction, distillation and evaporation work where uniform heat distribution and a secure ground-joint connection are required. The spherical body supports efficient mixing and thermal transfer, while the standardised NS 29/32 joint allows reliable coupling to condensers, adapters, stoppers and other ground-joint glassware in multi-neck or single-neck assemblies. Supplied as a pack of six pieces, this 2000 ml format suits preparative and process-scale laboratory tasks that need larger working volumes without frequent vessel changes. The flasks come from manufacturer Dinkelberg and are intended for routine use in chemistry, biochemistry and teaching laboratories. Country of origin is the Czech Republic. The clear designation of joint size and nominal capacity simplifies selection against existing glassware inventories and heating mantles or oil baths sized for two-litre round-bottom flasks. Ideal for solvent recovery, reflux setups and general synthetic work where a stable, round-bottom geometry is preferred over flat-bottom alternatives.
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, 2000ml, 6/PK
What is this article?
Flask with round bottom, with SJ 29/32, 2000ml, 6/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.
