Description
Round-bottom flask 1000 ml with two necks, centre neck NS 29/32 and straight side neck NS 29/32, is clear laboratory glassware produced from borosilicate glass 3.3. The nominal volume of 1 l accommodates larger-scale reactions, distillations and collection tasks that require matched standard ground joints. Both necks share the NS 29/32 size, simplifying apparatus assembly when identical joints are preferred, while the straight side-neck design preserves open vapour paths and straightforward access. Supplied as 1 pc with a net weight of 0,354 kg, the flask from manufacturer Witeg belongs to the familiar family of round-bottom, ground-joint, distillation and receiving flasks used across research, teaching and quality-control laboratories. Borosilicate glass 3.3 supplies the chemical resistance and thermal stability demanded by routine heating, cooling and vacuum work. Clear-glass walls permit uninterrupted visual monitoring of contents, boiling characteristics and phase changes throughout the process, supporting efficient multi-step organic and preparative workflows.
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 + SN
What is this article?
Round bottom flask 1000 ml two necks CN + SN 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.
