Description
Stopper VMQ transparent is a tapered silicone laboratory stopper with a lower diameter of 10,5 mm and an upper diameter of 14,5 mm. The one-hole design features a single 3 mm bore and an overall height of 20 mm, making it suitable for sealing glassware necks while allowing passage of tubing or probes. Manufactured from VMQ silicone, the stopper combines chemical resistance with flexibility and is supplied transparent for easy visual inspection of contents or fittings. With a net weight of only 0,00237 kg and offered as a single piece, it is a practical consumable for everyday laboratory sealing tasks. Produced by Deutsch & Neumann, this silicone stopper belongs to the standard range of rubber and silicone stoppers used in chemical, analytical and life-science laboratories. The tapered profile ensures a secure fit in matching openings, while the pre-drilled 3 mm channel supports simple assembly of gas lines, thermometers or sampling tubes. Ideal for routine work where a clean, resilient and transparent closure is required.

Questions about stopper VMQ, transparent, bottom diameter: 10,5 mm top diameter: 14,5 mm height:
What is this article?
stopper VMQ, transparent, bottom diameter: 10,5 mm top diameter: 14,5 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.
