Description
Round-bottom flask 2000 ml with three necks is a multi-neck laboratory flask for distillation, reaction and collection work. It combines a centre neck with NS 45/40 ground joint and two straight side necks with NS 29/32 joints, giving flexible connection points for condensers, dropping funnels, stirrers or thermometers. The vessel is made from clear borosilicate glass 3.3, which provides the chemical resistance and thermal shock tolerance required in everyday organic and preparative chemistry. Nominal volume is 2 l and net weight is 0,523 kg. Supplied as a single piece from manufacturer Witeg, the flask suits standard ground-joint assemblies used in research and industrial laboratories. The spherical body promotes even heating and efficient mixing, while the three-neck layout allows simultaneous reagent addition, temperature monitoring and vapour handling. Categories of use include round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks. Clear glass construction permits continuous visual observation of the contents throughout the process.
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 ST 45/40
What is this article?
Round bottom flask 2000 ml three necks CN ST 45/40 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.
