Description
Rotilabo®-stopper made of natural rubber is a tapered laboratory plug for sealing flasks, bottles and other vessel openings in everyday lab practice. It measures 94 mm at the bottom diameter, 107 mm at the top diameter and 65 mm in height, giving a clear dimensional profile for matching larger necks and wide openings. Formed from natural rubber, the stopper combines elasticity with a firm seating surface suited to temporary closure of glass and related laboratory vessels. Supplied as 1 pc with a unit weight of 0,605 kg, it fits standard inventory planning for plugs and related consumables. This Rotilabo® item from manufacturer ROTH SELECTION belongs to the stoppers and clamps segment of laboratory glassware and vessel accessories. Laboratories use such natural-rubber stoppers wherever a reliable mechanical seal is needed during preparation, storage or transfer steps. The defined bottom and top diameters support consistent selection against neck sizes, helping standardise stopper stocks across teaching, research and routine analytical workflows without relying on improvised closures.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-stopper made of natural rubber, Ø bottom 94 mm, Ø top 107 mm, H 65 mm
What is this article?
Rotilabo®-stopper made of natural rubber, Ø bottom 94 mm, Ø top 107 mm, H 65 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.
