uses of Cork to  fit test tube

Sample Storage:

Test tubes often contain samples of liquids or solids for analysis or storage. Cork stoppers provide a secure seal, preventing the contents from leaking or evaporating.

Chemical Reactions

In experiments where chemical reactions occur within test tubes, it’s important to seal the tubes to contain the reaction and its byproducts. Cork stoppers help maintain a closed environment, allowing for controlled reactions.

Transportation:

When transporting samples or conducting fieldwork, cork stoppers prevent spills or contamination of the contents within the test tubes.

Culture Growth:

Test tubes are commonly used in microbiology for growing cultures of microorganisms. Cork stoppers help create a closed environment conducive to microbial growth while preventing contamination from outside sources.

Preservation:

Cork stoppers can be used to seal test tubes containing sensitive materials that need to be preserved over time, such as biological samples or volatile compounds.
