Description
Round-bottom flask 3000 ml with three necks is a multi-neck laboratory flask intended for distillation, reaction and collection applications. It is equipped with a centre neck NS 45/40 and two straight side necks NS 29/32, enabling convenient attachment of condensers, addition funnels, stirrers or temperature probes. Manufactured from clear borosilicate glass 3.3, the flask offers the chemical durability and thermal stability expected in routine laboratory practice. Nominal volume is 3 l and net weight is 0,792 kg. This single-piece item from manufacturer Witeg integrates readily into standard ground-joint setups used in research and production environments. The rounded body supports uniform heat distribution and effective mixing, while the three-neck arrangement permits concurrent reagent dosing, monitoring and vapour management. Typical uses cover round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks. Transparent glass walls allow continuous visual control of the process contents.

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