Description
The red NR stopper is a solid rubber laboratory stopper designed for sealing flasks, bottles and laboratory glassware. It features a lower diameter of 87 mm, an upper diameter of 100 mm and a height of 65 mm, giving a reliable tapered fit in corresponding neck sizes. With zero boreholes, the stopper provides a full, airtight closure without openings for tubing. Produced from rubber in red, this NR stopper from Deutsch & Neumann supports everyday sealing needs in chemistry, biology and industrial lab environments. The unbored solid body helps contain liquids, powders and samples securely during storage or experimental work. Supplied as one piece with a net weight of 0,51709 kg, it inserts and removes smoothly while maintaining steady sealing pressure. A practical choice when a durable, simple rubber stopper is preferred over multi-hole versions for general laboratory vessels.

Questions about stopper NR, red, bottom diameter: 87 mm top diameter: 100 mm height: 65 mm
What is this article?
stopper NR, red, bottom diameter: 87 mm top diameter: 100 mm height: 65 mm 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.
