Description
Round-bottom flask 500 ml with two necks features a centre neck NS 24/29 and a straight side neck NS 19/26 for flexible laboratory setups. This clear-glass flask is manufactured from borosilicate glass 3.3 and is intended for distillation, reaction and collection work in the laboratory. The nominal volume of 0,5 l together with the two-neck configuration supports connection of condensers, dropping funnels or temperature probes via standard ground joints. With a net weight of 0,18 kg, the body is convenient to handle on the bench or in heating mantles. Available as a single piece from manufacturer Witeg, it integrates readily into existing NS joint assemblies. The round-bottom shape is well suited to heating and boiling procedures in organic synthesis and preparative chemistry. The straight side neck provides unobstructed access and secure clamping, making the flask useful as a distillation flask, receiving flask or multi-neck reaction vessel in research and quality-control 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 Matériel de laboratoire.
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.
