Description
Rotilabo® stoppers made of natural rubber are tapered laboratory plugs for sealing vessels, flasks and other glassware openings. Each stopper measures 47 mm at the bottom diameter, 55 mm at the top diameter and 40 mm in height, giving a clear size reference for matching common neck apertures. Natural rubber provides the elasticity needed for a firm, reusable seal in routine laboratory work. Supplied in packs of 5 pc(s) with a pack weight of 0,454 kg, these stoppers are practical consumables for stocking standard plug sizes. The tapered profile—narrower at the base and wider at the crown—helps seat securely when pressed into a suitable opening. These Rotilabo® stoppers from manufacturer ROTH SELECTION belong to the labware range for stoppers, clamps and plugs used with laboratory glass and vessels. Dimensions are specified so users can select the correct fit without guesswork. Suitable for general laboratory vessel closure where natural rubber stoppers are preferred, they support everyday handling of bottles, flasks and similar containers in research, teaching and quality-control environments.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-stoppers made of nat. rubber, Ø bottom 47 mm, Ø top 55 mm, H 40 mm
What is this article?
Rotilabo®-stoppers made of nat. rubber, Ø bottom 47 mm, Ø top 55 mm, H 40 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.
