Plural of ampul; small sealed glass vials usually containing a single dose of medication or chemical.
From Latin ampulla (flask) shortened to ampul, with -s forming the English plural. Originally referred to any small vessel, now standardized for pharmaceutical usage.
Medical ampuls are actually a direct descendant of ancient Roman bottles—pharmaceutical companies standardized this design because the sealed glass design perfectly preserves medications and prevents contamination, just like it did 2,000 years ago.
