Description
Round-bottom flask 2000 ml with three necks is a multi-neck laboratory flask intended for larger-scale distillation, reaction and collection tasks. It comprises one centre neck and two side necks, each equipped with an NS 29/32 ground joint; the side necks are angled at 20° to allow convenient attachment of condensers, dropping funnels or temperature probes while maintaining good access to the reaction mixture. Fabricated from clear borosilicate glass 3.3, the flask combines chemical durability with thermal stability for routine heating and cooling. The nominal volume of 2 l and net weight of 0,631 kg make it well suited to preparative organic chemistry, solvent concentration and multi-port assemblies. Offered as a single unit from manufacturer Witeg, this three-neck round-bottom flask fits standard ground-joint systems and supports both atmospheric and moderate-vacuum workflows where consistent joint dimensions and optical clarity are essential.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 2000 ml three necks CN + two SN
What is this article?
Round bottom flask 2000 ml three necks CN + two 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.
