Description
Two-necked adapter with parallel necks in DURAN® glass is a ground-joint component for assembling multi-neck reaction and distillation setups in the laboratory. It combines sockets NS 24/29 with a cone NS 24/29, allowing a second vertical connection path while the main joint remains aligned with standard flask and condenser geometry. Parallel neck orientation keeps added inlets, thermometers, dropping funnels or gas lines clear of the primary vapour path, which supports controlled reflux, inert-gas blanketing and simultaneous reagent addition. Supplied as a single piece weighing 0,097 kg, the adapter integrates cleanly into existing NS 24/29 glass trains used for organic synthesis, solvent recovery and extraction work. The component is offered from manufacturer Lenz and belongs to the family of ground-glass joint parts intended for distillation and extraction assemblies. Clear NS sizing simplifies matching to flasks, condensers and receivers already in use, reducing the need for intermediate reducers when building compact multi-port configurations on the bench or under a fume hood.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Two-necked adapter, DURAN®, paral. necks, sockets NS 24/29, cone NS 24/29
What is this article?
Two-necked adapter, DURAN®, paral. necks, sockets NS 24/29, cone NS 24/29 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.
