Description
Round-bottom flask 3000 ml NS 45/40 is a single-neck laboratory flask manufactured from borosilicate glass 3.3 in clear glass. Offering a nominal volume of 3 l and fitted with a standard ground joint NS 45/40 on a medium neck, it is intended for distillation, reaction and collection applications in laboratory practice. The flask measures 185 mm in outer diameter and 280 mm in height, providing a spherical body compatible with standard heating mantles and support systems. Available from manufacturer Witeg, this clear borosilicate glass 3.3 vessel functions as a round-bottom flask, ground-joint flask, distillation flask or receiving flask. The single medium neck with NS 45/40 joint allows direct connection to condensers, adapters and complementary taper glassware. Supplied as 1 piece, it is suitable for chemical, pharmaceutical and research laboratories that require larger-volume round-bottom glassware of defined dimensions and joint size for heating, mixing and solvent-handling procedures.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 3000 ml ST 45/40
What is this article?
Round bottom flask 3000 ml 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.
