Description
Attachment DN 60 with centre neck NS 29/32 and side necks NS 14/23 is a precision laboratory glassware component for flat-ground lid assemblies. It features one centre neck NS 29/32, three angled side necks at 15° with NS 14/23 joints, and one straight side neck NS 14/23, all fabricated from borosilicate glass. This configuration supports multi-port access for thermometers, dropping funnels, condensers or gas inlets on reaction vessels and distillation setups that use a DN 60 flat flange. The robust glass construction offers good chemical resistance and thermal stability for routine organic synthesis, solvent recovery and general laboratory work. Supplied as a single piece with a net weight of 0,27 kg, the attachment integrates cleanly with matching flat-ground lids and standard ground-joint glassware. The design from manufacturer Witeg provides a practical multi-neck solution for chemists who need several simultaneous connections without compromising seal integrity on the DN 60 flange. Suitable for use in research, teaching and process-development laboratories where reliable borosilicate attachments are required.
This article is part of Closures (other), in Stoppers, caps & closures.

Questions about Lid, flat flange, DN 60, CN ST 29/32, 3
What is this article?
Lid, flat flange, DN 60, CN ST 29/32, 3 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Closures (other), inside Stoppers, caps & closures, in Labware.
These are the closures that are not a plain screw cap, a rubber stopper or a ground-glass stopper. The question is still the same: does the closure match the mouth, and does the material survive the contents.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
