Description
Round lid stopper NS 60/46 is a semi-hollow ground-joint stopper intended for laboratory glassware with larger standard joints. Manufactured from SBW glass to DIN 12252, this round lid stopper delivers a dependable seal on NS 60/46 connections. The semi-hollow construction balances reduced weight with sufficient wall strength for everyday use on flasks, reactors and adapters. Net weight is 0,279 kg per piece, reflecting the larger joint size while remaining convenient to handle. The round lid geometry supports stable seating and straightforward placement or removal during experimental set-up. Supplied as a single unit, the stopper fits seamlessly into glassware assemblies used for synthesis, distillation, storage and general laboratory work. This item from manufacturer Witeg forms part of the proven range of norm ground-joint stoppers found in chemical and analytical laboratories. The glass material provides the chemical resistance typical of laboratory glassware and tolerates normal cleaning cycles. It is an appropriate choice whenever a precise NS 60/46 ground-joint closure is needed without extra fittings.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about ST-stopper, round plate,ST60/46
What is this article?
ST-stopper, round plate,ST60/46 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
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.
