Description
NS ground joint sleeve NS 14/23 PTFE is a laboratory sealing sleeve for standard conical ground joints of size NS 14/23. Fabricated from PTFE with an integrated grip collar and a wall thickness of 0,4 mm, it is intended for use on matching NS glassware joints. The PTFE sleeve provides a thin interface layer between ground joint surfaces in chemical, analytical and general laboratory apparatus. This single-piece article from manufacturer Witeg has a net weight of 0,002 kg and is supplied in a pack size of 1 piece. The grip collar supports convenient placement and removal of the sleeve on the joint. Typical laboratory contexts include assembly of flasks, condensers, adapters and other NS 14/23 components where a PTFE ground joint sleeve or collar-type gasket is required. Within the product family of ground joint sleeves, hat sleeves and collar gaskets, this NS 14/23 size addresses everyday glassware sealing and joint-protection needs. The 0,4 mm PTFE wall is dimensioned for the stated joint size, and the unit is ready for direct installation on corresponding laboratory glass joints.

Questions about ST-sleeve for joints ST14/23 PTFE
What is this article?
ST-sleeve for joints ST14/23 PTFE 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.
