Description
Cone NS50/42 extension is a male standard ground-joint component with integrated extension for laboratory glassware connections in NS 50/42. It is manufactured to DIN 12249 PRECISO with an outer diameter of 46 mm, a length of 180 mm and a wall thickness of 2,3 mm, delivering a stable, interchangeable joint geometry where additional length is needed. The extended NS core supports secure coupling in larger-scale distillation, reaction and transfer setups that benefit from extra reach or clearance. Offered as a single piece from manufacturer Witeg, this NS core with extension integrates into standard ground-joint assemblies used in chemical and analytical laboratories. PRECISO conformity to DIN 12249 ensures consistent taper dimensions for reliable mating with corresponding NS sockets and for interchangeability within modular glass systems. Belonging to the Normschliffe category, the component provides a straightforward means of extending NS 50/42 interfaces without custom fabrication. Controlled diameter, length and wall thickness support reproducible assembly and disassembly under typical laboratory conditions.
This article is part of Stand & rack accessories, in Stands, clamps & racks.

Questions about ST-Cone ST 50/42 skirted
What is this article?
ST-Cone ST 50/42 skirted is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Stand & rack accessories, inside Stands, clamps & racks, in Labware.
These are the extra rods, connectors, feet and labels that extend a stand or a rack. A right-angle connector is how a second rod leaves the first. The diameter has to match the rod already on the bench.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
