Description
Two-neck adapter NS 19/26 is a precision laboratory glassware component intended for distillation, reflux and multi-port reaction assemblies. It incorporates parallel necks fitted with ground joints of size NS 19/26 on both the cone and the sockets, permitting simultaneous connection of condensers, dropping funnels, thermometers or gas inlets. This geometry supports efficient vapour handling and controlled reagent addition during organic synthesis and analytical procedures. The compact design integrates readily into standard jointed glassware trains used in research and teaching laboratories. Supplied as a single piece with a net weight of 0,061 kg, the adapter originates from manufacturer Witeg. Parallel neck orientation simplifies spatial arrangement on crowded set-ups while maintaining vacuum-tight seals typical of NS 19/26 ground joints. Ideal for applications requiring two upper ports of identical size without intermediate adapters.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Multiple adapters ST 19/26
What is this article?
Multiple adapters ST 19/26 is the article on this page. Luminix Health distributes Witeg 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.
