Description
Round-bottom flask 500 ml with three necks provides a versatile multi-neck reaction and distillation vessel for laboratory synthesis and separation work. The centre neck is finished NS 24/29 while the two side necks are angled at 20° and finished NS 14/23, allowing simultaneous connection of condensers, dropping funnels, thermometers or gas inlets. Fabricated from clear borosilicate glass 3.3, the flask combines thermal shock resistance with excellent chemical durability and clear visibility of contents. Nominal volume is 0,5 l. This three-neck round-bottom flask from manufacturer Witeg is well suited to organic reactions, fractional distillation setups and collection duties where multiple ports are required on a single vessel. The angled side necks improve accessibility and reduce interference between attached apparatus. Pack size is one piece. Net weight is 0,211 kg. The clear-glass construction supports visual monitoring of boiling, colour changes and phase behaviour throughout experimental procedures 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 three necks CN ST 24/29
What is this article?
Round bottom flask 500 ml three 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 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.
