Description
Three-necked round-bottom flask, DURAN® is a larger multi-neck laboratory flask for reaction and distillation assemblies that require several simultaneous connections. This 1000 ml vessel provides two side necks with 14/23 ground joints and a centre neck with 29/32, so condensers, addition funnels, gas lines or measurement probes can be mounted together. The round-bottom form supports even heating and effective stirring at the one-litre scale in standard laboratory heating equipment. Packed as 1 pc with a weight of 0,330 kg, the flask is intended for use with conventional clamps and stands. DURAN® glass and standardised joint sizes maintain compatibility with common laboratory glassware. Offered from manufacturer Lenz, this three-neck layout suits preparative synthesis, solvent work-up and multi-step procedures where a central 29/32 working neck is combined with 14/23 side ports. Explicit neck designation (side 14/23, centre 29/32) aids correct matching to existing apparatus. Appropriate for research and routine laboratory environments needing a 1000 ml three-neck round-bottom flask in this configuration.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, DURAN®, 1000 ml, side necks 14/23, centre 29/32
What is this article?
Three-necked round-bottom flask, DURAN®, 1000 ml, side necks 14/23, 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 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.
