Description
Rotilabo® stoppers made of silicone rubber are tapered laboratory plugs for sealing glassware and vessels in routine lab work. Each stopper measures 14 mm at the bottom diameter, 18 mm at the top diameter and 20 mm in height, giving a conical profile that seats cleanly in matching openings. Silicone rubber provides the flexibility needed for repeated insertion and removal while supporting dependable closure of flasks, tubes and similar containers. These stoppers form part of the Rotilabo® range from manufacturer ROTH SELECTION and are packed as 100 pieces with a total pack weight of 0,440 kg. They sit in the stoppers and plugs segment of laboratory consumables and suit everyday sealing tasks where consistent dimensions matter. The wider top and narrower base help the plug stay in place during handling, storage or short-term reactions. Laboratories that need a ready supply of uniform silicone stoppers can use this multi-piece pack for general glassware workflows without over-specifying specialised closures.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-stoppers made of silic. rubber, Ø bottom 14 mm, Ø top 18 mm, H 20 mm
What is this article?
Rotilabo®-stoppers made of silic. rubber, Ø bottom 14 mm, Ø top 18 mm, H 20 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.
