Description
VMQ stopper, transparent, with lower diameter 3,5 mm and upper diameter 6,5 mm is a solid silicone laboratory stopper for sealing small openings in glassware and apparatus. The tapered body rises from 3,5 mm at the base to 6,5 mm at the top over a height of 15 mm, providing a secure fit in matching necks or ports. Made from transparent VMQ silicone, it combines the flexibility and chemical resistance typical of laboratory-grade silicone elastomers. The stopper is supplied without boreholes (0 bores), so it functions as a blank plug rather than a tubing adapter. Net weight is 0,00031 kg per piece. This stopper from manufacturer Deutsch & Neumann belongs to the silicone stopper range used for flasks, tubes and general sealing tasks in research and quality-control laboratories. Pack size is one piece, allowing precise replenishment of stopper assortments. Transparent material helps with visual checks at the seal interface. A compact, unbored silicone closure for everyday laboratory sealing needs.

Questions about stopper VMQ, transparent, bottom diameter: 3,5 mm top diameter: 6,5 mm height:
What is this article?
stopper VMQ, transparent, bottom diameter: 3,5 mm top diameter: 6,5 mm height: 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.
