Description
Replacement plug NS 14,5 solid is a solid ground-joint spare plug for laboratory stopcocks and glassware fitted with an NS 14,5 joint. It incorporates a 4 mm bore, giving a practical balance between flow capacity and control in chemical and analytical setups. The solid design delivers a durable sealing face and stable geometry for replacement of damaged or worn stopcock plugs on flasks, columns and connecting pieces. It is intended for routine glassware maintenance where dimensional match to standard NS joints and a defined bore are required to keep apparatus leak-tight and functional. Supplied as a single piece with a net weight of 0,018 kg from manufacturer Witeg, this plug supports everyday laboratory service work in research, quality control and teaching environments. Its solid body is suited to repeated assembly cycles while preserving the integrity of the ground-joint interface in typical lab glass systems.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about ST-seperate plug, ST 14 solid
What is this article?
ST-seperate plug, ST 14 solid 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.
