An ampule, also known as an ampoule, is a small, sealed vial or container used to store and dispense a liquid medication or solution. It is typically made of glass or plastic and is specifically designed to maintain the integrity and purity of the contents.
The ampule is hermetically sealed, ensuring that no air or contaminants enter or escape, thus preserving the contents in a sterile condition. The seal is typically made of a thin glass stem, which must be snapped or broken to access the liquid inside. Once opened, the ampule cannot be resealed, making it a single-use container.
The design of an ampule makes it particularly suitable for sensitive or precise dosing requirements. It allows for accurate measurement and withdrawal of the exact volume of liquid needed, typically using a syringe or needle. The small size of the ampule also makes it convenient for containing individual doses, especially in healthcare settings, where sterility and accurate dosage are crucial.
Ampules are widely used in various fields, including pharmaceuticals, medicine, laboratories, and research facilities. They are commonly used to store vaccines, injectable medications, and other solutions, such as serums or essential oils. Their hermetic sealing and sterile nature ensure that the contents remain safe and uncontaminated until ready for use.
In summary, an ampule is a small sealed container that preserves the sterility and purity of liquid medications or solutions. It is commonly used in healthcare settings and laboratories due to its single-use design, accurate dosing capabilities, and ability to maintain the integrity of its contents.
