Description
Socket NS 5/13 is a precision ground-joint component for laboratory glassware assemblies conforming to DIN 12249. It features an outer diameter of 8 mm, an overall length of 120 mm and a wall thickness of 0,8 mm, enabling secure, interchangeable connections in distillation, reaction and transfer setups. The socket is supplied as a single piece with a net weight of 0,008 kg, making it convenient for both routine apparatus construction and spare-part replacement. Ground joints of this size are widely employed in organic synthesis, analytical sample preparation and educational laboratories where standardised NS fittings ensure leak-tight seals under vacuum or atmospheric conditions. Produced by manufacturer Witeg, the component maintains dimensional accuracy required for reliable mating with corresponding cones. Its slender wall profile balances mechanical strength with ease of handling during assembly and cleaning. The NS 5/13 socket supports modular glass apparatus design and facilitates rapid reconfiguration of experimental trains without specialised tools.

Questions about Sleeve ST5/13
What is this article?
Sleeve ST5/13 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Grease, boiling stones & sealants, inside Tools & accessories, in Labware.
Grease seals a ground joint. Boiling stones give a liquid a place to start boiling so it does not bump. A sealant does the same job as grease when grease would contaminate the product. They are small, and they decide whether a joint weeps.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
