Description
Three-necked round-bottom flask DURAN® is a mid-capacity multi-neck laboratory flask designed for synthesis, reflux and multi-component reaction setups. With a 100 ml volume it suits preparative work that requires more side-joint clearance than smaller necks allow. The centre neck is 24/29 and the side necks are 19/26; the side necks are angled to improve instrument access and reduce interference between attached glassware. Manufactured from DURAN® borosilicate glass by manufacturer Lenz, the vessel provides the thermal shock resistance and chemical stability expected in standard laboratory practice. The round-bottom profile supports even heating and effective stirring on conventional mantles or baths. Supplied as one piece weighing 0,088 kg, this three-neck flask is compatible with common ground-joint systems and is appropriate for organic chemistry, process development and teaching laboratories that need simultaneous multi-port connectivity with larger side joints in a compact 100 ml format.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, 100 ml, Centre neck 24/29, side neck 19/26
What is this article?
Three-necked round-bottom flask, 100 ml, Centre neck 24/29, side neck 19/26 is the article on this page. Luminix Health distributes Lenz 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.
