Description
Rotilabo® stoppers made of natural rubber are tapered laboratory plugs for sealing flasks, bottles and other vessels in routine lab work. Each stopper has a bottom diameter of 18 mm, a top diameter of 24 mm and a height of 30 mm, giving a clear dimensional profile for matching common neck openings. Natural rubber provides the flexibility expected of classic laboratory stoppers used as temporary or everyday closures. Supplied in a pack of 25 pieces with a total weight of 0,300 kg, the set is practical for bench stock or central stores. The tapered form supports a snug fit in glassware and many plastic vessels within the stoppers and plugs category of laboratory consumables. These Rotilabo® stoppers from manufacturer ROTH SELECTION form part of a consistent size series for everyday sealing tasks. Dimensions are stated as bottom Ø 18 mm, top Ø 24 mm and height 30 mm so users can select the correct size for their vessels. The natural rubber construction and multi-piece pack suit general laboratory handling where reliable, simple plugs are required without additional hardware.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-stoppers made of nat. rubber, Ø bottom 18 mm, Ø top 24 mm, H 30 mm
What is this article?
Rotilabo®-stoppers made of nat. rubber, Ø bottom 18 mm, Ø top 24 mm, H 30 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.
