Description
Two-necked pear-shaped flask, 100 ml, DURAN® provides a versatile intermediate volume for jointed laboratory assemblies that need two access points. Both the centre neck and the side neck are NS 14/23, giving a matched pair of standard joints for condensers, addition funnels, stoppers or temperature probes. The pear-shaped profile keeps the working liquid pooled near the bottom, aiding magnetic stirring and uniform heating during reflux, concentration or small-batch synthesis. This DURAN® flask from manufacturer Lenz is intended for routine organic and general chemistry workflows where dual-neck convenience and compact footprint matter. Offered as one piece with a weight of 0,065 kg, it integrates readily into existing NS 14/23 glassware sets used in research, quality-control and teaching laboratories. Consistent joint dimensions support modular apparatus design without adapters when all components share the same NS size.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Two-necked pear shaped fl., 100ml,DURAN®, Centre neck NS 14/23
What is this article?
Two-necked pear shaped fl., 100ml,DURAN®, Centre neck NS 14/23 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.
