Commonly, rubber stoppers are used in scientific experiments to plug and test tubes. Their purpose is to prevent liquids, and sometimes gases, from escaping their containers.
rubber stoppers are used for a variety of things cars, door stops, test tube caps, brakes, and printer rollers
they are used to stop liquids or fumes from exiting a test tube or flask

Rubber stopper can stop the air into the bottle,and protect the material not go bad inside the bottle
use to cover the test tube
Rubber stoppers are widely used for the commercial, industrial and scientific markets. They are made from different types of rubber and available in various sizes and styles depending on applications.What are Rubber Stoppers used for?Possible uses of rubber stoppers are wide and varied such as :Mechanical StopBumpersVibration MountGrippersClampsSticky feet for platformFits into Test Tubes, Boiling FlaskPipe stoppersPaint masksTube plugsDoor stopperThe kind of rubber stopper used in chemical laboratories is a plug which fits into the top of a test tube or flask, often with a hole or holes bored in it for the insertion of a piece of glass tubing. They used to be made of cork but rubber is less likely to disintegrate and get into the contents of the flask or tube.

A cork borer is used to make a hole through the middle of a cork stopper, usually in order to insert a delivery tube through it. Now that synthetic rubber bungs can be readily bought with the holes already made, and interchangeable ground glass joints are relatively cheaper than they used to be, cork stoppers are used less frequently. If you do need to use the procedure, get someone to show you how to do it safely, particularly the insertion of the glass tube when the hole is made.
nothing happens because the glass would not get through the rubber ( some rubber would pass) it depends what kind of rubber you use
From Wikipedia:A bung is truncated cylindrical or conical closure to seal a container, such as a bottle, tube or barrel. Unlike a lid which encloses a container from the outside without displacing the inner volume a bung is partially inserted inside the container to act as a seal. The lids for safety overpacks for 55 gallon drums sometimes may have a bung built in for access of the contents of the container. These may be referred to as fuel bungs.A rubber stopper is sometimes called a rubber bung, and a cork stopper is called a cork. Sometimes bung stoppers used for wine bottles are referred to as "corks", even though made from another material.
use to cover the test tube, basically like a cork.
There are many formulations of rubber, so it depends on which formulation of rubber you use. Pharmaceutical rubber stoppers are made of Butyl rubber which is unaffected by alcohol.
to bore holes in rubber stoppers or to cut out pieces of agar in Petri dishes
The density of rubbers stoppers can be very different from one to the next. This is because there are different stoppers at different densities.
Normally cork or rubber is used as a stopper in a flask.
Heating at high temperature can be dangerous.
I think you are talking about cleats. If that is the case then yes, they are safer than metal but wear out sooner. Also the shoe must be the interchangeable kind.

Vulcanized rubber was invented in 1841 by Charles Goodyear, and the new substance was immediately put into use for many purposes. In 1842 a man called Brockedon reported to the British Chemistry Association that he had invented a stopper for use in chemistry which was a cotton cord bound with flax and coated with rubber. Solid hard rubber stoppers were used to close beer and liquor bottles in Britain by the 1880s, using the internal screw stopper patented by Henry Barrett in 1872. Such stoppers were extremely popular in both Britain and America between 1880 and 1920 or so.

Discounting any ridiculous side-usage for rubber stoppers that may exist, they are simply used to seal glasswear in a temporary manner. For example, if you want to shake your solution but don't want to get it all over yourself. Or if you want to transport it and minimize risk of spillage. We generally don't use rubber stoppers much anymore, though. Glass stoppers are considered safer since they will pop out more easily if pressure builds inside the glasswear (which can be VERY dangerous). I would never stopper anything that I am applying heat to or that I expect gas production from, so be careful in your usage. Glass stoppers are also a little better because you know if your solution isn't reacting with your glasswear, it won't react with the stopper....whereas it may still react with a rubber stopper. Another advantage is that glass stoppers are easier to remove (try greasing them if they leak air or don't work smoothly). A good example is if you are using a separating funnel you will usually want to shake the funnel and then relieve the pressure by removing the stopper (at very regular intervals). This can be a pain with a rubber stopper as they require more force, which can also lead to accidents. Again, glass stoppers make this much easier. Cork stoppers are used similarly.
Rubbers stoppers are used in laboratory for: - to close bottles - to close tubes - to make a link between tubes or other laboratory objects - to make link with perforated stopper
