Description
Round-bottom flask, 100 ml, socket NS 14,5/23 is a single-neck laboratory vessel fabricated from borosilicate glass 3.3 with a medium neck and precision ground joint NS 14,5/23. The 100 ml nominal capacity combined with the classic spherical shape delivers uniform heat transfer ideal for reactions, distillations and sample receiving. Net weight is 0,050 kg, providing a sturdy yet manageable piece that resists thermal shock and most laboratory chemicals. Offered as one piece, the flask mates directly with standard condensers, adapters and other NS 14,5/23 components for vacuum or open systems. It serves routinely as a distillation flask, receiving flask or general reaction vessel in organic chemistry, purification and analytical workflows. This item from manufacturer Rettberg is made in Germany and aligns with established ranges of round-bottom, ground-joint, distillation and receiving flasks. The dependable ground-joint connection ensures leak-tight seals and rapid set-up, while the borosilicate material supports repeated use under demanding thermal and chemical conditions. Research, teaching and quality-control laboratories rely on such flasks for reproducible performance and easy integration into modular glassware trains.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask, 100 ml, socket size 14,5/23
What is this article?
Round bottom flask, 100 ml, socket 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.
