Description
Transparent VMQ silicone stopper with a lower diameter of 87 mm and an upper diameter of 100 mm is a solid conical laboratory stopper for sealing larger glassware and vessels. Standing 65 mm high and free of pre-drilled bores, it provides a full seal while remaining adaptable for custom openings when required. The VMQ silicone construction offers the elasticity and chemical resistance typical of vinyl-methyl silicone rubber in laboratory environments. Its transparent appearance supports visual inspection of the vessel neck and contents. Delivered as a single piece with a net weight of 0,49786 kg, the stopper is ready for use on flasks, bottles and similar containers. This stopper from manufacturer Deutsch & Neumann belongs to a standardised range of silicone laboratory stoppers employed in chemical, analytical and general research settings. The tapered geometry ensures progressive contact along compatible openings for a secure yet removable fit. It is well suited to routine sealing applications that call for a durable, flexible silicone closure without factory-formed holes.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about stopper VMQ, transparent, bottom diameter: 87 mm top diameter: 100 mm height: 65
What is this article?
stopper VMQ, transparent, bottom diameter: 87 mm top diameter: 100 mm height: 65 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.
