There are various types of plastic test tube stoppers commonly used in laboratories. The following are some of the most common types:

4. Piston stoppers: Piston stoppers are plastic stoppers that can be pushed in or out. They are typically used in experiments that require the release of a sample from the test tube
5. Magnetic stoppers: Magnetic stoppers are test tube stoppers that have a magnet embedded in them. They are used in experiments that require mixing or stirring of the contents of the test tube. 
6. Freezing stoppers: Freezing stoppers are plastic test tube stoppers that can withstand extremely low temperatures. They are typically used in experiments that require freezing or low-temperature storage of samples. These are some of the most common types of plastic test tube stoppers, and different types can be chosen based on the needs of the experiment.
