Description
NR grey rubber stopper with lower diameter 60 mm, upper diameter 70 mm and height 50 mm is a solid laboratory closure intended for sealing larger flasks, bottles and vessels. Produced from resilient rubber in a practical grey finish, the carefully tapered profile ensures a dependable friction fit that seats firmly yet can be inserted and withdrawn without difficulty. With no boreholes the stopper creates a complete seal, making it ideal for storage, mixing or transport applications that do not require tubing or probes. Supplied as a single piece weighing 0,2013 kg net, it is manufactured by Deutsch & Neumann and finds routine use in chemistry, biology, pharmaceutical and teaching laboratories. The balanced flexibility and firmness of the rubber support repeated use on Erlenmeyer flasks, reagent bottles and custom glassware while helping to keep contents free from dust and moisture. This robust solid stopper offers a reliable everyday solution for general laboratory sealing whenever material compatibility with rubber has been verified.

Questions about stopper NR, grey, bottom diameter: 60 mm top diameter: 70 mm height: 50 mm
What is this article?
stopper NR, grey, bottom diameter: 60 mm top diameter: 70 mm height: 50 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.
