Description
Three-neck adapters NS 19/26 are precision laboratory glassware components designed for multi-port distillation and reaction setups. Each adapter features a central ground-joint core of NS 19/26 together with two lateral sockets of the same NS 19/26 size, enabling simultaneous connection of condensers, dropping funnels, thermometers or other apparatus to a single flask neck. This configuration supports organic synthesis, reflux, fractionation and reagent addition without requiring dedicated multi-neck flasks. Produced by manufacturer Witeg, the adapters weigh 0,063 kg net and are supplied as individual pieces for modular glassware systems. The compact design maintains secure, leak-resistant joints when properly prepared and is suitable for both atmospheric and moderate vacuum work typical of preparative chemistry. Ideal for research and teaching laboratories, these three-neck adapters expand connection options on round-bottom flasks and similar vessels while preserving compatibility with standard NS 19/26 assemblies. Their robust construction ensures reliable performance in routine distillation and reaction workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about MULTIPLE ADAPTERS, 3 NECKS, CONE ST 19/
What is this article?
MULTIPLE ADAPTERS, 3 NECKS, CONE ST 19/ 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.
