Beschreibung
Round-bottom flask 5000 ml NS 29/32 is a clear glass laboratory vessel featuring a single medium neck and standard ground joint NS 29/32. Made from borosilicate glass 3.3, it serves distillation, reaction and collection applications in the laboratory. The flask has a nominal volume of 5 l, an outer diameter of 223 mm and a height of 335 mm, providing a stable footprint for heating mantles and stands. Supplied as one piece from manufacturer Witeg, this round-bottom flask supports organic synthesis, solvent recovery and preparative work where uniform heating and secure joints are essential. The NS 29/32 ground joint permits direct connection of condensers, adapters or vacuum fittings. Its single-neck design and robust borosilicate construction are intended for repeated laboratory use in research, analytical and production settings that depend on large-volume round-bottom glassware for distillation and collection tasks.
This article belongs on Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 5000 ml ST 29/32
What is this article?
Round bottom flask 5000 ml ST 29/32 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Laborbedarf.
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.
