Description
3-Neck flask 2000 ml with centre neck NS 29/32 and two straight side necks NS 14,5/23 is a large-capacity multi-neck laboratory vessel made of borosilicate glass 3.3. The three precision ground joints allow concurrent attachment of condensers, addition funnels, stirrer guides or temperature probes, supporting complex distillation, reflux and synthetic workflows. With a nominal volume of 2 l the flask accommodates larger reaction batches while the straight side-neck arrangement facilitates straightforward clamping and apparatus layout. Borosilicate glass 3.3 provides the chemical inertness and thermal stability expected in demanding laboratory environments. Offered as a single unit from manufacturer Rettberg, the vessel has a net weight of 0,530 kg and forms part of the standard range of round-bottom and ground-joint flasks employed in research, process development and analytical laboratories. It is suitable for atmospheric work and mild vacuum service when used with compatible joint seals.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about 3-neck bottom flask, 2000 ml, mn size 29/32, 2x sn size 14,5/23
What is this article?
3-neck bottom flask, 2000 ml, mn size 29/32, 2x sn size 14,5/23 is the article on this page. Luminix Health distributes Rettberg 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.
