Description
Two-neck adapter with angled socket NS 24/29 is a precision glass component for distillation and multi-neck laboratory set-ups. It features one angled socket, a cone joint of NS 24/29 and socket joints of NS 19/26, permitting convenient side connection of condensers, addition funnels or temperature probes while the principal neck remains available for the main vapour stream. The angled layout reduces bench clutter and improves ergonomics during prolonged reflux or fractional distillation procedures. Delivered as a single unit weighing 0,053 kg net, the adapter is manufactured by Witeg in Germany and is classified among distillation adapters. Standardised NS ground joints ensure compatibility with existing glassware inventories and allow reliable sealing with joint grease or PTFE sleeves. Typical uses encompass organic synthesis, solvent recovery and preparative work where an extra access port is needed without changing the flask size. Low dead volume and straightforward assembly make the fitting suitable for both atmospheric and vacuum operations common in research and analytical laboratories.

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