Questions about Suction tube, with ST-stopcock, straig
What is this article?
Suction tube, with ST-stopcock, straig is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Glazen slijpstoppen, inside Stoppen, doppen & sluitingen, in Labmateriaal.
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.
