Description
Ground joint sleeve NS 24/29 is a laboratory accessory for sealing standard conical ground glass joints of size NS 24/29. It is supplied with grooves and a wall thickness of 0,05 mm, allowing it to sit between matching male and female joint surfaces in glass apparatus. The thin-walled, grooved construction is typical for this class of joint sleeve and supports fitting on NS 24/29 cones used throughout chemical and analytical glassware. Pack size is 1 pc(s), with a net weight of 0,004 kg and a gross weight of 0,004 kg. This ground joint sleeve from manufacturer Witeg is intended for routine laboratory assemblies where standardized NS joints are employed, including reaction setups, distillation trains and general glass apparatus. Categories associated with the article include ground joint sleeves, hat-type sleeves, collar sleeves and collar seals. The defined NS 24/29 size ensures dimensional compatibility with corresponding ground joints, while the 0,05 mm wall and grooved profile characterize the product for everyday laboratory use.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Sleeves ST 24/29
What is this article?
Sleeves ST 24/29 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.
