Ampules are hermetically sealed glass capsules that usually contain liquid, especially a premeasured quantity ready for injecting or dispersing, and serve to preserve the purity and extend the content's shelf-life. Pre-scored ampules have a constricted stem that allows for safe opening and eliminates the need for filing. The stems on glass ampules, which offer excellent dimensional stability for high-speed filling and sealing operations, can be pull or tip-sealed, with no preservatives required because of their airtight seal. These products include easy-to-use single-use ampule breakers.
