Description
Rotilabo® stoppers made of natural rubber are tapered laboratory plugs for sealing vessels and glassware. Each stopper measures 10,5 mm at the bottom diameter, 14,5 mm at the top diameter and 20 mm in height, giving a defined conical profile for common laboratory openings. Natural rubber provides the elasticity needed for a snug, reusable seal on flasks, bottles and tubes in routine laboratory work. The pack contains 25 pieces and has a total weight of 0,076 kg, supporting efficient stocking of this everyday consumable. These Rotilabo® stoppers from manufacturer ROTH SELECTION suit research, teaching and quality-control environments where reliable dimensional fit and simple handling matter. The tapered form eases insertion and removal while maintaining closure integrity during standard bench procedures. Clear sizing allows quick selection of the correct plug for matching neck diameters. As part of the broader labware range for stoppers and plugs, this natural-rubber variant offers a practical option for general sealing tasks without complex accessories.

Questions about Rotilabo®-stoppers made of nat. rubber, Ø bottom 10.5 mm, Ø top 14.5 mm, H 20 mm
What is this article?
Rotilabo®-stoppers made of nat. rubber, Ø bottom 10.5 mm, Ø top 14.5 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.
