Description
Round-bottom flasks with a nominal capacity of 100 ml and standard ground joint NS 24/29 are fundamental glassware items for distillation, reflux heating and chemical reactions. Manufactured from borosilicate glass 3.3 in accordance with DIN EN ISO 4797, the short-neck design combines thermal-shock resistance with broad chemical durability. The NS 24/29 socket ensures secure, leak-tight coupling to condensers, adapters, dropping funnels and other jointed apparatus commonly used in organic and inorganic work. These flasks from manufacturer Marienfeld are packed in cartons of 10 pieces, making them convenient for stocking teaching laboratories, research groups and quality-control environments. The round-bottom geometry promotes uniform heating on heating mantles or oil baths and facilitates efficient mixing with magnetic stirrers. Suitable for routine preparative chemistry, solvent recovery and sample concentration where durable, standardised borosilicate glassware is required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks 100 ml with round bottom and ground joint
What is this article?
Boiling flasks 100 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 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.
