Description
Round-bottom flask 50 ml NS 29/32 is a single-neck laboratory flask intended for distillation, synthesis and collection duties. Fabricated from clear borosilicate glass 3.3, it provides a nominal volume of 0,05 l with a medium neck finished as ground joint NS 29/32. Outer diameter measures 51 mm and height 90 mm, yielding a classic spherical shape that promotes uniform heat transfer and mixing. The single medium neck simplifies assembly with condensers, dropping funnels or vacuum adapters while keeping the setup compact. Offered by manufacturer Witeg, this flask supports everyday organic chemistry, solvent concentration and intermediate storage in research and teaching environments. Borosilicate glass 3.3 delivers the chemical resistance and thermal stability needed for common laboratory reagents and moderate temperature changes. Packed in units of 10 pieces, the vessels serve as round-bottom, ground-joint, distillation or receiving flasks and integrate directly into existing NS 29/32 glassware trains without adapters.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 50 ml ST 29/32
What is this article?
Round bottom flask 50 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 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.
