Description
Round-bottom flask 500 ml with three necks provides a versatile multi-neck vessel featuring a centre neck NS 29/32 and two straight side necks NS 14/23. Fabricated from clear borosilicate glass 3.3, the flask delivers reliable chemical durability and thermal stability for routine and advanced laboratory procedures. Its nominal volume of 500 ml (0,5 l) is appropriate for larger-scale synthesis, fractional distillation and multi-reagent reaction sequences that require concurrent attachment of condensers, addition funnels or sensors. The straight side necks enable secure ground-joint connections, while the round-bottom profile ensures uniform heating on standard laboratory heaters. Clear glass construction permits unobstructed observation of reaction progress, crystallisation and boiling dynamics. Offered as one piece with a net weight of 0,194 kg, this flask from manufacturer Witeg serves effectively as a reaction vessel, distillation flask or collecting flask in academic, industrial and analytical laboratories. The three-neck layout supports adaptable experimental arrangements while maintaining the mechanical strength and optical clarity expected of borosilicate laboratory glassware under repeated thermal cycling.
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 29/32
What is this article?
Round bottom flask 500 ml three necks CN 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 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.
