Round-bottom flask 500 ml with two necks serves as a versatile reaction and distillation vessel for medium-scale laboratory work. The centre neck carries an NS 24/29 ground joint while the side neck is angled at 20° and finished with an NS 19/26 joint, allowing concurrent connection of condensers, addition funnels or sensors. Clear glass construction from borosilicate glass 3.3, supplied by manufacturer Witeg, delivers the chemical and thermal resistance expected in everyday synthesis and solvent-handling tasks. Nominal volume is 0,5 l; the classic round-bottom geometry supports uniform heat distribution and stirring. Net weight is 0,181 kg, keeping the flask practical for clamp stands and heating mantles. Ideal for use as a round-bottom flask, ground-joint flask, distillation flask or receiving flask, the angled two-neck layout simplifies multi-component setups without excessive bulk. Offered as one piece for straightforward replacement or expansion of existing glassware assemblies in research and teaching laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 500 ml two necks CN ST 24/29 +
What is this article?
Round bottom flask 500 ml two necks CN ST 24/29 + is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labmateriaal.
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.
