Description
Safety tube NS 14/23, also known as a fermentation attachment (Gäraufsatz), is a ground-joint laboratory component designed for connection via the standard NS 14/23 joint. This safety tube from manufacturer Witeg serves as a protective or venting attachment in glassware assemblies where a ground joint interface of NS 14/23 is required. The unit is supplied as a single piece and is intended for use in setups that benefit from a dedicated safety or fermentation-style tube on the joint. With a net weight of 0,05 kg it remains a compact addition to standard jointed apparatus. Suitable for laboratories working with Normschliff glassware, the safety tube integrates directly onto matching NS 14/23 sockets. Its straightforward design supports reliable mechanical connection without additional adapters when the joint size matches. The component is listed for use in ground-joint applications and provides a practical solution for fermentation or safety-tube functions on NS 14/23 systems.

Questions about Safety tube (Thistle funnels), ST 14/23
What is this article?
Safety tube (Thistle funnels), 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.
