Description
Two-necked adapter, DURAN®, with parallel necks is a ground-glass joint component that adds an extra working neck to laboratory glass assemblies. It features sockets NS 19/26 and a cone NS 19/26, allowing connection into existing NS 19/26 systems while providing parallel necks for simultaneous attachments such as a thermometer, dropping funnel, gas inlet or condenser path. Built in DURAN® quality associated with manufacturer Lenz, the adapter supports modular construction of distillation, extraction and multi-neck reaction glassware. Parallel neck orientation keeps accessories aligned and accessible in compact setups on stands or in fume hoods. Supplied as a single unit weighing 0,065 kg, it belongs to glass components with ground-glass joints used across laboratory glass, vessels and consumables. The NS 19/26 joint standardisation helps laboratories maintain interchangeable apparatus when expanding a single-neck flask or intermediate joint into a two-neck configuration for controlled addition, monitoring or vapour handling during routine synthetic and preparative work.
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 19/26, cone NS 19/26
What is this article?
Two-necked adapter, DURAN®, paral. necks, sockets NS 19/26, cone NS 19/26 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.
