FAQ
Frequently Asked Questions
No, it is used in both British and American English, but the spelling differs. British English uses 'ampoule', while American English prefers 'ampule' or 'ampul'.
No, ampoules are designed as single-use, sterile containers. Once opened, the sterility is compromised, and they are discarded.
An ampoule is typically a sealed glass container that must be broken open, designed for a single use. A vial is a bottle with a rubber stopper that can be pierced multiple times, potentially holding multiple doses.
Using a special file or a protective wrap, you score the neck of the ampoule and then snap it cleanly away from yourself to avoid injury from glass shards.
