Description
Three-necked round-bottom flask, DURAN® in the 10000 ml size is built for large-volume laboratory reactions that still rely on standard ground-joint apparatus. Both side necks and the centre neck are 29/32, giving a uniform joint system for condensers, addition funnels, gas inlets and sensors across all three ports. The round-bottom DURAN® construction supports controlled heating and stirring of substantial batches in organic synthesis, solvent recovery and preparative work. Supplied as 1 pc and weighing 2,423 kg, the flask is a substantial piece of labware intended for stable mounting in large mantles or baths. From manufacturer Lenz, it extends the range of round flasks with ground glass joints into higher capacities while keeping familiar NS 29/32 connectivity. Equal neck sizes simplify stock of stoppers, adapters and clamps and make it straightforward to reconfigure the setup between runs. This configuration is appropriate when multi-neck access is essential at the 10000 ml scale and laboratories prefer consistent joint dimensions on centre and side ports for safer, more modular assemblies.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, DURAN®, 10000ml, side necks 29/32, centre 29/32
What is this article?
Three-necked round-bottom flask, DURAN®, 10000ml, 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 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.
