What is the term for sealed glass containers holding sterile solutions?

The term for sealed glass containers that hold sterile solutions is an ampule. Ampules are typically made of glass and are designed to contain a single dose of a medication or solution that must remain sterile until opened. They are hermetically sealed, which helps to protect the contents from contamination and degradation. When using an ampule, it is important to break the neck of the container correctly to maintain sterility and to ensure that no glass particles contaminate the solution being drawn out for administration.

While vials are also used to hold sterile solutions, they generally have rubber stoppers that allow for multiple uses and the ability to withdraw the contents with a syringe. A vial may contain preservatives, allowing for multiple doses over time. Bags are commonly used for larger volumes of intravenous solutions but are typically made of flexible material rather than glass. An admixture refers to a compounded solution that includes multiple medications or compounds but is not itself a container type. Thus, the characteristics of an ampule make it the correct choice for this question.
