Description
Round-bottom flask with NS 29/32 is a classic laboratory flask format combining a spherical body with a standardised ground joint for secure connection to other glassware. This version provides a nominal volume of 250 ml and an NS 29/32 joint, allowing straightforward integration into distillation, reflux and reaction assemblies that already use this joint size. The round bottom favours uniform heating and mixing when paired with heating mantles, baths or stirrers commonly found in research and quality-control laboratories. Supplied in a pack of 10 pieces, the set supports multi-user environments, parallel runs and teaching practicals. These round-bottom flasks from manufacturer Dinkelberg are listed under laboratory materials and are aimed at everyday laboratory workflows requiring a dependable NS 29/32 interface. Country of origin is the Czech Republic. The 250 ml capacity offers a practical middle ground between small-scale trials and larger preparative batches, while the consistent joint geometry supports reliable sealing with standard joint treatment. Suitable for synthesis steps, solvent recovery, concentration work and general sample processing on the bench or in the fume hood.

Questions about Flask with round bottom, with SJ 29/32, 250ml, 10/PK
What is this article?
Flask with round bottom, with SJ 29/32, 250ml, 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.
