Description
Round-bottom flask 100 ml with two necks is a clear laboratory flask equipped with a centre neck NS 29/32 and an angled side neck NS 14/23 at 20°. Produced from borosilicate glass 3.3, the vessel combines chemical durability with good thermal-shock resistance for routine distillation, reaction and collection tasks. The two-neck arrangement enables concurrent attachment of condensers, addition funnels or sensors, while the round bottom promotes uniform heating of the contents. Nominal volume is 0,1 l and net weight is 0,069 kg, offering a practical size for preparative organic chemistry and teaching laboratories. This ground-joint flask from manufacturer Witeg is intended for use as a distillation or receiving flask where standard NS joints and clear observation of the mixture are required. Clear glass construction supports continuous visual control throughout multi-step procedures. Supplied as a single piece, it fits directly into conventional laboratory assemblies using NS 29/32 and NS 14/23 connections.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 100 ml two necks CN ST 29/32 +
What is this article?
Round bottom flask 100 ml two 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 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.
