An AMPULE is a small, sealed glass or plastic vial containing a liquid medication. It is commonly used to store and transport medicinal substances, such as antibiotics, hormones, and other drugs. The term 'AMPULE' is derived from the Latin word 'AMPULLA, ' which means 'small bottle.' Ampules are typically made of glass, but can also be made of plastic. They are often used in medical settings, such as hospitals, clinics, and pharmacies.
