A test tube brush is a specialized cleaning tool designed for cleaning the inside of test tubes and similar narrow containers. It typically consists of a long, thin handle with a soft, flexible brush at the end. The brush is made of a material that is resistant to chemicals and can withstand repeated use.

Test tube brushes are essential for maintaining the cleanliness of laboratory glassware. They are used to remove dirt, debris, and contaminants from the inside of test tubes, ensuring that the glassware is clean and ready for use. Test tube brushes are also used to clean other types of narrow containers, such as vials, pipettes, and burettes.

The use of test tube brushes dates back to the early days of laboratory science. In the 19th century, scientists began using test tubes as a way to store and manipulate small samples of chemicals and biological materials. Test tube brushes were developed as a way to clean these tubes and ensure that they were free of contaminants.
