Description
VMQ stopper, transparent, with lower diameter 5 mm and upper diameter 9 mm is a solid silicone laboratory stopper designed to close small openings in glassware and laboratory apparatus. Its tapered profile runs from 5 mm at the bottom to 9 mm at the top across a height of 20 mm, enabling a firm seal in correspondingly sized necks or ports. Manufactured from transparent VMQ silicone, the stopper offers the elasticity and chemical resistance associated with silicone materials used in laboratory environments. It is supplied without boreholes (0 bores) and therefore serves as a blank plug rather than a hose or tubing adapter. Net weight is 0,00087 kg and gross weight 0,001 kg per piece. This stopper from manufacturer Deutsch & Neumann forms part of the standard silicone stopper assortment for flasks, tubes and general sealing applications. Pack size is one piece for accurate stock replenishment. Transparent construction supports visual inspection of the sealed area. A practical unbored silicone closure for routine laboratory use.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about stopper VMQ, transparent, bottom diameter: 5 mm top diameter: 9 mm height: 20 mm
What is this article?
stopper VMQ, transparent, bottom diameter: 5 mm top diameter: 9 mm height: 20 mm 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.
