Description
Rotilabo® stopper made of natural rubber is a solid tapered laboratory plug intended for sealing larger flasks, bottles and vessels in everyday laboratory practice. Dimensions are a bottom diameter of 64,5 mm, a top diameter of 75,5 mm and a height of 55 mm, so the stopper can be matched directly to openings of corresponding size. Natural rubber delivers the flexibility and grip expected for temporary closures that must seat firmly yet remain removable. The item is supplied as one piece and weighs 0,264 kg, supporting straightforward stock management of labware consumables. This Rotilabo® stopper from manufacturer ROTH SELECTION fits the stoppers and plugs category used across research, teaching and analytical laboratories. Its tapered form helps achieve even contact around the vessel neck for reliable short-term sealing. Choose this size when protocols or glassware sets call for a natural-rubber stopper with the stated bottom, top and height measurements.

Questions about Rotilabo®-stopper made of natural rubber, Ø bottom 64.5 mm, Ø top 75.5 mm
What is this article?
Rotilabo®-stopper made of natural rubber, Ø bottom 64.5 mm, Ø top 75.5 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.
