What is vial definition?

A vial is a small cylindrical, flat-bottomed container used for holding liquid medicines or other substances. It is typically made of glass or plastic and sealed with a cap or stopper. Vials are generally smaller than bottles and used for storing small amounts of liquids, such as medication, vaccines, or samples. They are commonly used in the pharmaceutical and biotech industries for packaging and dispensing drugs, vaccines, and other medical products. Vials can be sterilized and used for long-term storage of liquids, powders, or dry samples. They come in various shapes, sizes, and materials, depending on the specific application.
