Description
Ground joint sleeve NS 24/29 is a PTFE sleeve intended for standard conical ground joints of size NS 24/29 in laboratory glassware. Wall thickness is specified as 0,05 mm, providing a thin PTFE layer between corresponding male and female ground surfaces. The article belongs to the group of ground joint sleeves, hat sleeves, collar sleeves and collar seals used on flasks, condensers, distillation setups and adapters. It is offered as 1 pc, with net weight 0,001 kg and gross weight 0,001 kg. This PTFE ground joint sleeve from manufacturer Witeg is of German origin (Baden-Württemberg) and is classified under UNSPSC 41104812. The NS 24/29 marking matches the widely used European standard taper series, allowing direct pairing with glassware already specified for that joint size. As a dedicated manschette it functions as a sealing accessory within laboratory joint-sleeve and collar-seal ranges for everyday chemical and analytical applications.

Questions about PTFE-Sleeves ST 14/29
What is this article?
PTFE-Sleeves ST 14/29 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.
