Description
Transparent VMQ silicone stopper featuring a lower diameter of 12,5 mm and an upper diameter of 16,5 mm is a solid laboratory stopper for secure closure of glassware and process vessels. Standing 20 mm high and free of bore holes, the conical design creates a continuous silicone seal that resists many common laboratory chemicals. The transparent VMQ material combines elasticity with good thermal behaviour and allows the sealed neck to remain visible. Easy insertion and removal make it convenient for repeated use in routine workflows. This stopper from manufacturer Deutsch & Neumann is intended for general laboratory sealing applications that call for a non-bored silicone plug in these dimensions. Supplied as one piece with a net weight of 0,00346 kg, it serves research, quality-control and educational settings that need dependable, transparent silicone stoppers with a clear conical geometry and no pre-drilled openings.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about stopper VMQ, transparent, bottom diameter: 12,5 mm top diameter: 16,5 mm height:
What is this article?
stopper VMQ, transparent, bottom diameter: 12,5 mm top diameter: 16,5 mm height: is the article on this page. Luminix Health distributes Deutsch & Neumann for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
