Description
VMQ silicone stopper, transparent, with a lower diameter of 26 mm and an upper diameter of 32 mm is a solid laboratory closure for sealing flasks, bottles and other vessels. Made of silicone (VMQ), the stopper has a height of 30 mm and is supplied without boreholes, giving a continuous sealing face where no tubing, thermometer or probe passage is needed. The tapered profile (narrower end 26 mm, wider end 32 mm) supports secure insertion into matching openings. Net weight is 0,0216 kg. This transparent silicone stopper from manufacturer Deutsch & Neumann belongs to the standard range of laboratory stoppers used in chemistry, life-science and analytical work. The clear material allows visual inspection of the stopper and of the vessel neck when glassware is transparent. Supplied as 1 pc, it is ready for research, quality-control and teaching laboratories that require reliable silicone closures. Its defined dimensions and solid construction make it a practical choice for temporary or longer-term sealing of containers holding samples, reagents or intermediate products under typical laboratory conditions.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about stopper VMQ, transparent, bottom diameter: 26 mm top diameter: 32 mm height: 30
What is this article?
stopper VMQ, transparent, bottom diameter: 26 mm top diameter: 32 mm height: 30 is the article on this page. Luminix Health distributes Deutsch & Neumann 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.
