4-Neck flask, 3000 ml, with 4 baffles is a multi-neck laboratory reaction vessel intended for synthesis, distillation and preparative work that requires simultaneous access for stirring, reagent addition and monitoring. Fabricated from borosilicate glass 3.3, the flask combines high chemical resistance with good thermal-shock performance. It is equipped with a centre neck NS 29/32, two side necks NS 29/32 and one side neck NS 14,5/23; the side necks are angled at 7° to improve handling and reduce interference between attachments. Four internal baffles promote turbulent mixing when a mechanical stirrer is used, supporting efficient heat and mass transfer. A bottom drain valve with an adjustable opening of 0–10 mm permits controlled emptying without dismantling the set-up. Nominal volume is 3 l and net weight is 0,980 kg. This design from manufacturer Rettberg is supplied as a single piece and is well suited to organic synthesis, process development and pilot-scale operations in research and industrial laboratories where multi-port connectivity and reliable drainage are essential.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about 4-neck flask, 3000 ml, with 4 baffles, mn size 29, sn 2x size 29, 1x size 14,5,
What is this article?
4-neck flask, 3000 ml, with 4 baffles, mn size 29, sn 2x size 29, 1x size 14,5, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
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.
