Description
Round-bottom flask 50 ml with two necks is a clear laboratory flask featuring a centre neck NS 29/32 and an angled side neck NS 14/23 set at 20°. Manufactured from borosilicate glass 3.3, it provides the chemical resistance and thermal stability needed for distillation, synthesis and collection work in organic and analytical chemistry. The dual-neck layout permits simultaneous connection of condensers, dropping funnels or temperature probes, while the spherical bottom supports even heat distribution. Nominal volume is 0,05 l and net weight is 0,063 kg, giving a compact format suited to small-scale preparative and teaching applications. This ground-joint flask from manufacturer Witeg belongs to the standard clear-glassware range used as distillation and receiving vessels. Optical clarity of the glass allows continuous visual monitoring of reaction mixtures and phase changes. Supplied as one piece, it integrates directly into setups that require reliable NS 29/32 and NS 14/23 joints.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 50 ml two necks CN ST 29/32 +
What is this article?
Round bottom flask 50 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.
