Questions about Stopcock, straight bore, solid glass plug size 14,5/2,5 mm bore
What is this article?
Stopcock, straight bore, solid glass plug size 14,5/2,5 mm bore is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
