Description
VMQ silicone stopper, transparent, is a solid laboratory stopper intended for closing flasks, bottles and similar vessels. Manufactured from silicone (VMQ), it has a lower diameter of 60 mm, an upper diameter of 70 mm and a height of 50 mm. The stopper is supplied without bores (Bohrungen: 0), giving a fully closed sealing surface. Net weight is 0,18236 kg and gross weight is 0,19 kg. Transparency of the silicone allows visual inspection at the sealed neck when used with clear laboratory glassware. Offered by manufacturer Deutsch & Neumann, this item forms part of the standard silicone-stopper assortment for research, quality-control and educational laboratories. The tapered geometry and stated diameters help achieve a reliable fit in corresponding openings. Packaged as one piece, the stopper is suitable for routine laboratory sealing applications that call for an undrilled VMQ stopper of these dimensions.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about stopper VMQ, transparent, bottom diameter: 60 mm top diameter: 70 mm height: 50
What is this article?
stopper VMQ, transparent, bottom diameter: 60 mm top diameter: 70 mm height: 50 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.
