Description
Three-necked round-bottom flask, DURAN® is a multi-neck laboratory vessel with a 3000 ml capacity, two side necks 29/32 and a centre neck 29/32. The round-bottom form supports even heat transfer when the flask is used with heating mantles, oil baths or other standard laboratory heating equipment. Ground joints on all three necks allow simultaneous connection of condensers, dropping funnels, stirrer guides, thermometers or gas inlets in a single setup. This DURAN® flask from manufacturer Lenz is intended for organic synthesis, preparative work, distillation and other multi-port reaction procedures that benefit from a larger working volume and flexible joint access. Visual observation of the contents remains straightforward through the clear glass wall. The article is supplied as 1 pc(s) and has a weight of 0,766 kg, making it suitable for routine clamping on laboratory stands. The combination of 3000 ml volume with matched 29/32 side and centre necks provides a practical configuration for medium-scale laboratory chemistry where several accessories must operate together on one vessel.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, DURAN®, 3000 ml, side necks 29/32, centre 29/32
What is this article?
Three-necked round-bottom flask, DURAN®, 3000 ml, side necks 29/32, centre 29/32 is the article on this page. Luminix Health distributes Lenz 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.
