Description
Round-bottom flask 2,000 ml, narrow neck is durable laboratory glassware manufactured from borosilicate glass 3.3 for distillation, heating and larger-scale reaction work. The single narrow neck finished with a beaded rim accommodates stoppers and adapters securely while limiting solvent loss and supporting precise transfers. A nominal volume of 2 l provides ample capacity for preparative chemistry, solvent recovery and collection of distillates. Borosilicate glass 3.3 delivers high chemical resistance together with low thermal expansion, ensuring stability during rapid temperature changes on heating mantles or in oil baths. Supplied six pieces per carton from manufacturer Marienfeld, the flasks are practical for laboratory inventory management. The round bottom promotes even heat transfer essential for reflux and rotary evaporation, while the clear glass wall permits continuous visual observation of contents throughout processes common in organic synthesis and analytical sample preparation.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks with round bottom 2'000 ml, narrow neck
What is this article?
Boiling flasks with round bottom 2'000 ml, narrow neck is the article on this page. Luminix Health distributes Marienfeld 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.
