Questions about stopper NBR, black, bottom diameter: 94 mm top diameter: 107 mm height: 65 mm
What is this article?
stopper NBR, black, bottom diameter: 94 mm top diameter: 107 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.
