Description
Round-bottom flask, 10000 ml, socket NS 45/40 is a single-neck laboratory vessel manufactured from borosilicate glass 3.3, equipped with a centre neck and NS 45/40 ground joint. With a nominal volume of 10 l and a net weight of 2,100 kg, the flask serves distillation, reaction and collection tasks in chemical and pharmaceutical laboratories. The spherical base ensures even heat distribution during heating-mantle or bath operations, while borosilicate glass 3.3 provides excellent resistance to thermal shock and chemical attack. Delivered as a single piece, this flask from manufacturer Rettberg connects securely to standard ground-joint components via the NS 45/40 socket, facilitating assembly of condensers, adapters and receivers. It is well suited for large-volume solvent recovery, preparative distillation and as a receiving vessel for substantial liquid quantities. The single centre-neck configuration simplifies set-up, cleaning and maintenance, supporting efficient laboratory workflows. Robust construction allows repeated use under typical thermal cycling and handling conditions encountered in research and scale-up environments.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask, 10000 ml, socket size 45/40
What is this article?
Round bottom flask, 10000 ml, socket size 45/40 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.
