Description
Evacuation attachment NS 14/23 is a laboratory glassware component equipped with a standard ground joint of size NS 14/23 for vacuum and evacuation work on modular apparatus. The attachment provides a dedicated interface for removing air or establishing reduced-pressure conditions on flasks, vessels and related glass assemblies that use the NS 14/23 joint standard. Supplied as 1 pc, the unit has a net weight of 0,03 kg and a matching gross weight of 0,03 kg, keeping the added mass on the setup minimal. Produced in Germany in the Baden-Württemberg region by manufacturer Witeg, it fits European laboratory glassware systems built around interchangeable conical joints. The NS 14/23 size supports straightforward coupling to compatible condensers, adapters and reaction vessels used in synthesis, distillation and drying lines. Its compact form allows integration into existing trains without major reconfiguration. Research, teaching and quality-control laboratories that maintain NS-based glass inventories can employ this evacuation attachment as a practical single-piece accessory for controlled atmosphere or vacuum procedures requiring a reliable jointed connection point.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Vacuum control stopcock, ST 14/23
What is this article?
Vacuum control stopcock, ST 14/23 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
