Description
Stirring attachments with fused bearing sleeve NS 45/40 incorporate a fused bearing sleeve of 10 mm and a core joint NS 45/40 for laboratory stirring setups. These attachments connect to matching ground-joint glassware and support standard mixing operations in research environments. The unit is supplied as 1 pc and has a net weight of 0,105 kg together with a gross weight of 0,105 kg. Produced by manufacturer Witeg in Germany (Baden-Württemberg region), the design follows the stated fused-sleeve construction for use with NS 45/40 apparatus. The compact format integrates readily into existing stirring assemblies while maintaining the specified joint geometry. Laboratory workflows that rely on standardised ground joints benefit from the defined 10 mm sleeve dimension and NS 45/40 core. The product belongs to the stirring-closures category and provides the mechanical interface required between stirrer and vessel. Consistent dimensional data ensure straightforward pairing with compatible flasks and reactors used in everyday laboratory practice.

Questions about Stirrer guides, w. fused-on stirrer bea
What is this article?
Stirrer guides, w. fused-on stirrer bea 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.
