Description
Three-neck adapters NS 24/29 are precision laboratory glassware fittings intended for multi-port distillation and reaction apparatus. Each unit incorporates a central ground-joint core of NS 24/29 and two side sockets of identical NS 24/29 size, allowing three separate pieces of glassware to be attached to one flask opening. This arrangement is particularly useful for simultaneous reagent addition, temperature monitoring and vapour take-off during organic synthesis, reflux or fractional distillation. Manufactured by Witeg, the adapters have a net weight of 0,124 kg and are supplied individually for integration into standard borosilicate glassware systems. The design provides secure joint connections suitable for atmospheric and moderate vacuum applications common in preparative chemistry. Research and teaching laboratories benefit from the flexibility of expanding connection points on round-bottom flasks without investing in dedicated three-neck vessels. Robust construction and full NS 24/29 compatibility ensure reliable performance across routine distillation and reaction workflows requiring modular multi-neck configurations.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Multiple adapters, 3 necks, cone ST 24
What is this article?
Multiple adapters, 3 necks, cone ST 24 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.
