Description
Round-bottom flask 1000 ml with two necks is a clear-glass laboratory vessel manufactured from borosilicate glass 3.3 for reliable chemical and thermal resistance in everyday laboratory work. The centre neck is finished as NS 24/29 ground joint and the straight side neck as NS 14/23, providing standard connections for condensers, dropping funnels, thermometers or other jointed glassware. With a nominal volume of 1 l this two-neck flask is well suited to distillation, reflux, reaction and collection setups where simultaneous addition or measurement is required. The round-bottom geometry promotes uniform heating and efficient mixing when used with appropriate heating mantles or oil baths. Supplied as a single piece from manufacturer Witeg, the flask integrates readily into existing borosilicate glass assemblies and supports common organic-synthesis, analytical and preparative workflows. Its robust construction and standardised joints make it a practical choice for teaching laboratories as well as research and quality-control environments that demand reproducible glassware configurations.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 1000 ml two necks CN ST 24/29 +
What is this article?
Round bottom flask 1000 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 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.
