A test tube is a common piece of laboratory glassware used for holding, mixing, or heating small quantities of liquids or solid samples. Typically made of glass or plastic, test tubes are cylindrical with a rounded bottom and an open top. They come in various sizes, but most are relatively small, allowing them to fit into test tube racks or holders for easy organization.
