Description
Round-bottom flask 1000 ml with three necks is a multi-neck laboratory flask designed for distillation, synthesis and collection work. It features one centre neck and two side necks, all finished with NS 29/32 ground joints; the side necks are set at a 20° angle to facilitate simultaneous addition of reagents, stirring or connection of condensers and receivers. The vessel is produced from clear borosilicate glass 3.3, giving high chemical resistance and good thermal-shock performance under typical laboratory heating and cooling cycles. With a nominal volume of 1 l and a net weight of 0,366 kg, the flask provides a stable, transparent reaction space suitable for organic preparations, solvent recovery and multi-component setups. Supplied as a single piece from manufacturer Witeg, this three-neck round-bottom flask integrates readily into standard ground-joint assemblies and supports both atmospheric and moderate-vacuum operations where reliable joint geometry and optical clarity are required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 1000 ml three necks CN + two SN
What is this article?
Round bottom flask 1000 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.
