Description
Round-bottom flask with NS 29/32 is a laboratory glass vessel with a nominal volume of 1000 ml for heating, boiling, distillation and general reaction applications. The spherical body supports uniform heat transfer with heating mantles or baths and allows efficient swirling and mixing while limiting local overheating relative to flat-bottom containers. A standard ground joint NS 29/32 provides a secure, interchangeable fit to condensers, adapters, funnels and other NS glassware in single-neck or multi-component setups. Delivered as a pack of 10 pieces, these flasks meet the needs of teaching laboratories, research teams and routine analytical work that require a one-litre working volume and consistent joint dimensions. The geometry follows established European NS joint practice, enabling straightforward combination with existing glassware for organic synthesis, sample work-up and wet-chemistry procedures. Round-bottom flasks from manufacturer Dinkelberg originate from the Czech Republic and are grouped with laboratory materials used as glass reaction vessels. They offer a standardised choice when NS 29/32 connectivity and a 1000 ml capacity are specified.
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, 1000ml, 10/PK
What is this article?
Flask with round bottom, with SJ 29/32, 1000ml, 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.
