Description
Rotilabo® stoppers with hole, natural rubber, are laboratory plugs designed with a central borehole so vessels can be sealed while still allowing tubing, glass rods or sensors to pass through. Each unit features a borehole diameter of 6 mm and a bottom diameter of 26 mm, suited to frequently used flask and tube openings in routine laboratory practice. Natural rubber construction supplies the flexibility and resilience needed for a tight, conforming seal on glassware necks. The through-hole supports straightforward assemblies for filtration, gas handling, temperature measurement or controlled addition of reagents. Supplied in packs of 10 pc(s) weighing 0,230 kg in total, the stoppers form part of the Rotilabo® line from manufacturer ROTH SELECTION and align with standard categories for stoppers, plugs and clamps. The tapered shape and elastic material help achieve a secure fit without extra adapters in many everyday applications. Clear dimensional data enables quick matching to existing glassware stocks in general chemistry, teaching labs and preparative workflows that call for a natural-rubber stopper with a defined borehole.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-stoppers w. hole, nat. rubber, Ø borehole 6 mm, Ø bottom 26 mm
What is this article?
Rotilabo®-stoppers w. hole, nat. rubber, Ø borehole 6 mm, Ø bottom 26 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.
