Description
VMQ stopper, transparent, is a solid silicone laboratory stopper intended for reliable sealing of vessels and glassware. It features a lower diameter of 94 mm and an upper diameter of 107 mm, giving a conical profile that seats securely in matching openings. Height is 65 mm and the stopper has no borings, ensuring a complete, uninterrupted seal. Fabricated from transparent silicone (VMQ), the material permits visual checks while providing the flexibility and chemical resistance expected of silicone elastomers in laboratory use. This stopper from manufacturer Deutsch & Neumann is offered as a single piece with a net weight of 0,56452 kg. It suits routine laboratory tasks such as closing flasks, bottles or reaction vessels where an airtight, hole-free closure is required. The transparent finish and solid construction make it a practical choice among standard and silicone stoppers for general laboratory sealing applications.

Questions about stopper VMQ, transparent, bottom diameter: 94 mm top diameter: 107 mm height: 65
What is this article?
stopper VMQ, transparent, bottom diameter: 94 mm top diameter: 107 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.
