Description
neoChoice round-bottom flasks are single-neck laboratory flasks made from borosilicate glass 3.3, offering a nominal volume of 100 ml (0,1 l) and a larger ground joint size NS 29/32. The round-bottom geometry supports uniform heating and efficient mixing for reflux, distillation, synthesis, and collection duties, while the NS 29/32 joint provides a robust, widely used interface to condensers, still heads, and other standard ground-joint components. A single neck keeps assemblies simple for routine preparative chemistry, solvent work-up, and receiving applications. Borosilicate glass 3.3 supplies the thermal and chemical resistance expected in daily laboratory service with aqueous media and many organic reagents. Typical use spans round-bottom, ground-joint, distillation, and receiving flask roles on the bench or in heating baths. Delivered as a pack of 10 pieces from manufacturer neolab - Labor, these neoChoice 100 ml flasks help maintain interchangeable stock where the broader NS 29/32 joint is preferred for secure connections and higher mechanical stability in teaching, QC, and research environments.
This article belongs on Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about neoChoice Rundkolben 100 ml, NS 29/32, 10 St./Pack
What is this article?
neoChoice Rundkolben 100 ml, NS 29/32, 10 St./Pack is the article on this page. Luminix Health distributes neolab 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.
