Vial
A vial is a small container with a narrow neck, usually made of glass or plastic, for holding liquids, powders, or specimens.
Stopper: A plug or cap that closes the opening of a container. A stopper seals a vial’s narrow neck and helps prevent spills or contamination.
Pharmaceutical packaging: The materials and systems used to contain, protect, and deliver medicines. Vials package injectable drugs and other medicines that need sealed storage.
Crimp seal: A closure formed by pressing a metal cap around a container’s neck. Crimp seals secure stoppers on many injectable-drug vials.
Ampoule: A sealed glass container opened by breaking its narrow neck. Unlike a reusable vial, an ampoule is usually opened destructively and used once.
Borosilicate glass: A heat-resistant glass containing silica and boron trioxide. Borosilicate glass withstands temperature changes and is used for laboratory vials.
Vaccine vial: A small sealed container used to store and dispense vaccine doses. Vaccine vials are a specialized use of vials in immunization programs.
Septum: A thin, pierceable membrane that seals a container opening. A vial septum lets a needle access contents while limiting exposure to air.
Test tube: A slender cylindrical laboratory vessel with an open top and rounded bottom. Test tubes are generally used for experiments, while vials are made for storing or transporting contents.
Polypropylene: A thermoplastic polymer used to make durable, chemically resistant containers. Polypropylene vials offer a lightweight alternative to glass for many samples.
Sample vial: A small container used to collect, store, or transport a specimen for analysis. Sample vials hold substances such as blood, soil, or chemical solutions.
