Description
Flat ground lid DN 120 is a multi-neck laboratory lid for flat-flange vessels with nominal diameter DN 120. The flange outer diameter is 158 mm. Configuration includes a centre neck NS 29/32, one straight side neck NS 14/23 and two angled side necks NS 29/32, giving flexible access for stirring, dosing, temperature probes or reflux apparatus. Supplied as one piece, the lid is intended for synthesis, reaction and process glassware where several simultaneous connections are required on a DN 120 flat flange. This component from manufacturer Witeg matches planschliff and flat-flange reactor systems used in research and production laboratories. Net weight is 0,8 kg. Joint sizes follow standard NS designations so the lid integrates readily with common condensers, dropping funnels and adapters. The combination of a central neck with one straight and two inclined side necks supports compact multi-port assemblies without additional adapters on the flange face itself.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about Lid flat flange DN 120
What is this article?
Lid flat flange DN 120 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
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.
