Rubber plugs are commonly used in laboratory apparatus to seal openings in containers, such as test tubes, flasks, and bottles, preventing contamination and evaporation of samples. They create airtight seals, which are essential for experiments requiring controlled environments or reactions. Additionally, rubber plugs can accommodate various sizes of openings and can be easily removed for access to the contents when needed. Their flexibility and durability make them ideal for repetitive use in laboratory settings.
