Description
Round-bottom flask 20000 ml with three necks is a large-capacity laboratory vessel designed for distillation, reaction and collection work on a multi-litre scale. The centre neck carries a standard ground joint NS 45/40, while the two straight side necks are finished with NS 29/32 joints, giving flexible access for condensers, dropping funnels or temperature probes. Manufactured from clear borosilicate glass 3.3, the flask combines high thermal-shock resistance with excellent chemical durability, making it suitable for demanding organic and inorganic procedures. The nominal volume of 20 l and a net weight of 4,05 kg reflect its robust construction for pilot-scale or preparative applications. This three-neck configuration from manufacturer Witeg supports simultaneous addition, stirring and vapour take-off without compromising joint integrity. Categories such as round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks underline its versatility in synthesis and purification workflows. Supplied as a single piece, the flask is ready for integration into existing glassware assemblies that require large working volumes and standardised NS joints.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 20000 ml three necks CN
What is this article?
Round bottom flask 20000 ml three necks CN 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.
