Description
Round-bottom flask 1000 ml with two necks is a clear laboratory flask made from borosilicate glass 3.3, designed for distillation, reaction and collection work under standard ground-joint setups. It features a centre neck with NS 29/32 joint and an angled side neck at 20° with NS 19/26 joint, allowing convenient connection of condensers, dropping funnels or other glassware while keeping the main axis free. The nominal volume is 1 l and the vessel is supplied as clear glass for good visibility of contents and reaction progress. With a net weight of 0,333 kg, the flask offers a practical balance of capacity and handling for bench-scale organic synthesis, solvent recovery and multi-neck assemblies. This two-neck round-bottom flask from manufacturer Witeg is suitable for heating, reflux and vacuum applications typical of chemical and pharmaceutical laboratories when used with compatible joints and supports. The combination of borosilicate glass 3.3, defined joint sizes and the angled side neck supports flexible apparatus configurations in research and quality-control environments.
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 29/32 +
What is this article?
Round bottom flask 1000 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.
