Description
Pear shape flasks, DURAN®, equipped with standard ground joint 29/32 and a 50 ml capacity are designed for laboratory applications that need a wider joint interface together with a pear-shaped body. The geometry focuses the liquid at the base, supporting efficient thermal contact and stirring when processing moderate sample volumes. The larger standard ground joint 29/32 mates securely with corresponding condensers, multi-neck adapters, vacuum take-offs and other NS 29/32 glassware. Made from DURAN® glass by manufacturer Lenz, the flask is appropriate for organic synthesis, distillation trains, concentration steps and general preparative chemistry in research and teaching environments. It is supplied as 1 pc and weighs approximately 0,060 kg, remaining practical to clamp and manoeuvre on the bench or over a heating source. The combination of 50 ml working volume and NS 29/32 connectivity suits setups where a broader joint is preferred for throughput or apparatus compatibility. Laboratories standardising on 29/32 ground joints can integrate this pear-shaped DURAN® flask as a reusable vessel within their existing round-flask and jointed-glassware collections.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Pear shape flasks, DURAN®, standard ground joint 29/32 50 ml, 1 unit(s)
What is this article?
Pear shape flasks, DURAN®, standard ground joint 29/32 50 ml, 1 unit(s) 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.
