A rubber stopper is a small, tapered plug used to seal the openings of test tubes, flasks and other laboratory glassware. Stoppers made of cork are also available for this purpose. However, rubber stoppers are preferable for applications that require a tighter seal or a greater degree of chemical resistance. Purpose The primary purpose of a rubber stopper is to prevent a gas or liquid from escaping its container during a scientific experiment. Rubber stoppers can also prevent the contamination of samples by protecting the contents of laboratory glassware from air. Last, the use of rubber stoppers allows experimenters to shake or mix solutions without spilling them.
