About This Product
Rubber stoppers are used to close test tubes, flasks and bottles during storage, mixing and simple experiments. A tapered stopper is pushed into the neck of the glassware with the narrow end going in first. Neoprene is chosen where contact with oils or common acids and bases is expected, and the listed temperature limit should be kept in mind when stoppers are used with warm glassware. They are handy in the school lab for sealing sample bottles and holding set-ups together.
