Description
Rotilabo® stoppers with hole, natural rubber, are laboratory plugs fitted with a central borehole for tubing, probes or similar accessories while sealing the vessel neck. This variant offers a borehole diameter of 3 mm and a bottom diameter of 14 mm, giving a compact fit for smaller openings in flasks, bottles and other labware. Natural rubber provides the elasticity needed for a secure, reusable seal under typical bench conditions. The stoppers are packed as 25 pc(s) with a total weight of 0,125 kg, supporting routine stocking in teaching, research and quality-control laboratories. From manufacturer ROTH SELECTION, the Rotilabo® line is intended for everyday sealing tasks where both closure and through-access are required. The tapered stopper geometry helps seat firmly against the glass or plastic rim, while the defined borehole keeps an open path for connections. These plugs belong to standard laboratory consumables for stoppers and clamps and suit chemistry, biology and general analytical workflows that rely on simple, dimensionally consistent rubber closures.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-stoppers w. hole, nat. rubber, Ø borehole 3 mm, Ø bottom 14 mm
What is this article?
Rotilabo®-stoppers w. hole, nat. rubber, Ø borehole 3 mm, Ø bottom 14 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 Matériel de laboratoire.
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.
