Description
Round-bottom flask 50 ml with standard ground joint NS 24/29 is a laboratory glassware item intended for distillation, reaction and collection work. Fabricated from borosilicate glass 3.3, the flask incorporates a short neck and a female ground socket of size NS 24/29 in full accordance with DIN EN ISO 4797. This configuration ensures reliable, leak-tight connections to condensers, adapters and other ground-joint apparatus. The product from manufacturer Marienfeld combines high chemical resistance with excellent thermal-shock stability, making it suitable for routine heating, reflux and solvent-recovery operations. Its nominal volume of 50 ml supports small-scale synthetic and analytical procedures while the spherical body promotes uniform heat distribution when used with heating mantles or baths. Supplied as a carton of 10 pieces, the flasks are ready for immediate laboratory use. Categories encompass round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks, underscoring their versatility across organic synthesis, sample preparation and general laboratory workflows that demand dimensional accuracy and durable glass construction.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks 50 ml with round bottom and ground joint
What is this article?
Boiling flasks 50 ml with round bottom and ground joint is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Matériel de laboratoire.
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.
