Description
Rotilabo® stoppers made of natural rubber are solid tapered plugs intended for closing laboratory vessels and glassware. This size offers a bottom diameter of 50,5 mm, a top diameter of 59,5 mm and a height of 45 mm, allowing straightforward matching to openings in that range. Natural rubber delivers the flexibility and grip associated with classic laboratory stoppers for repeated seating and removal. Packs contain 5 pc(s) and weigh 0,600 kg, supporting convenient replenishment of frequently used plug sizes. The conical form—smaller at the bottom and larger at the top—assists in forming a reliable seal when inserted into a compatible neck or aperture. These Rotilabo® stoppers from manufacturer ROTH SELECTION sit within the stoppers and plugs segment of laboratory glass, vessels and consumables. Clearly stated dimensions help laboratories choose the correct stopper for flasks, bottles and similar containers. They are suited to general labware applications where natural rubber stoppers are specified for everyday vessel closure in research, education and analytical settings.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-stoppers made of nat. rubber, Ø bottom 50.5 mm, Ø top 59.5 mm, H 45 mm
What is this article?
Rotilabo®-stoppers made of nat. rubber, Ø bottom 50.5 mm, Ø top 59.5 mm, H 45 mm is the article on this page. Luminix Health distributes Carl Roth 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.
