Vial vs. Ampoule: Know the Difference

By Shumaila Saeed || Updated on December 27, 2023

A vial is a small bottle typically used for storing liquids, whereas an ampoule is a sealed glass or plastic bulb containing a dose of medication or a sample, usually meant to be broken open for use.

Vial vs. Ampoule

Key Differences

Vials are small containers made of glass or plastic used for holding liquid or powdered medications, samples, or chemicals. Ampoules, however, are typically small glass or plastic vessels, hermetically sealed to contain a sterile pharmaceutical liquid or a sample.

Dec 27, 2023

The design of a vial usually includes a screw cap or a stopper, making it reusable and suitable for multiple uses. In contrast, ampoules are designed for single use; they are sealed and need to be broken to access the contents, ensuring sterility and preventing contamination.

Dec 27, 2023

Vials can vary in size but are generally larger than ampoules, accommodating more content. Ampoules are often used for precise, single-dose applications, particularly in medical and scientific settings, ensuring an exact dosage.

Dec 27, 2023

In terms of material, vials can be made from a variety of materials, including glass and plastic, offering flexibility in usage. Ampoules are primarily made of glass for their ability to maintain sterility and integrity of the contained substance.
