Description
Transparent VMQ silicone stopper with a lower diameter of 79 mm and an upper diameter of 92 mm is a solid conical laboratory stopper intended for sealing glassware and vessels. With a height of 65 mm and no pre-drilled bores, it forms a complete seal and can be adapted later if openings are needed. Manufactured from VMQ silicone, the stopper combines the flexibility and chemical resistance characteristic of vinyl-methyl silicone rubber for routine laboratory work. The transparent design permits easy visual checks around the neck and sealed contents. Supplied as one piece with a net weight of 0,41496 kg, it is suitable for flasks, bottles and comparable containers. This stopper from manufacturer Deutsch & Neumann forms part of a standardised silicone stopper range used across chemical, analytical and general laboratory environments. Its tapered profile ensures progressive contact with compatible openings, delivering a secure yet removable fit. The solid construction without bores makes it a practical choice for sealing tasks that require a durable, flexible silicone plug.

Questions about stopper VMQ, transparent, bottom diameter: 79 mm top diameter: 92 mm height: 65
What is this article?
stopper VMQ, transparent, bottom diameter: 79 mm top diameter: 92 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.
