Description
Round-bottom flask 4000 ml with three necks is a multi-neck laboratory vessel for distillation, synthesis and collection work. It combines a centre neck with NS 24/29 ground joint and two side necks with NS 19/26 joints set at a 20° angle, giving flexible access for condensers, dropping funnels, gas inlets or temperature probes. The clear glass body is manufactured from borosilicate glass 3.3 by Witeg, delivering the thermal shock resistance and chemical durability required in routine organic and preparative chemistry. With a nominal volume of 4 l, the flask suits larger-scale reactions, solvent recovery and multi-component setups that need simultaneous addition and reflux. The classic round-bottom geometry promotes uniform heating in mantles or oil baths and stable clamping on standard laboratory stands. Typical use cases include distillation trains, receiving flasks and reaction vessels in research and teaching laboratories. Supplied as one piece, net weight 0,956 kg, it integrates readily into existing ground-joint glassware assemblies.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 4000 ml three necks CN ST 24/29
What is this article?
Round bottom flask 4000 ml three necks CN ST 24/29 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.
