Description
Round-bottom flask 100 ml with three necks is a laboratory glassware item featuring a centre neck and two side necks, all finished with NS 29/32 ground joints. The two side necks are angled at 20°, supporting flexible set-ups for simultaneous connection of condensers, dropping funnels, stirrers or temperature probes. Manufactured from borosilicate glass 3.3 as clear glass, the flask has a nominal volume of 100 ml (0,1 l) and a classic round bottom suited to even heating with mantles or oil baths. This three-neck configuration from manufacturer Witeg is intended for chemical synthesis, distillation and multi-port reaction work in research, teaching and preparative laboratories. Supplied as a single piece with a net weight of 0,118 kg, it integrates directly into standard NS 29/32 jointed glassware assemblies. The clear borosilicate construction permits continuous visual observation of contents during reaction, distillation or collection procedures, while the standardised joints ensure reliable mating with complementary laboratory components.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 100 ml three necks CN + two SN
What is this article?
Round bottom flask 100 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.
