Ampule
Ampule (pronounced as /ˈæmpjuːl/), also spelled as ampoule, is a small sealed vial which is used to contain and preserve a sample, usually a solid or liquid. Ampules are made of glass.
Etymology
The word "ampule" is derived from the Latin word "ampulla", which means flask. It was first used in the mid-17th century.
Usage
Ampules are commonly used in the healthcare industry to store pharmaceutical substances, especially those that are intended to be sterile until the time of use. They are hermetically sealed by melting the thin top with an open flame, and opened by snapping off the neck.
