What is the difference between ampoules and vials?

Ampoule, a type of sealed small bottle made of high-quality thin glass, is often used to store injectable drugs, vaccines, serums, etc. The common type is for medical use, and the medication used for intravenous drip is generally in ampoules. Vial, a small bottle sealed with a rubber stopper, comes in brown, transparent, and other varieties, generally made of glass. The neck of the bottle is relatively narrow, and the thickness below the neck is consistent. The mouth of the bottle is slightly wider than the neck and slightly narrower than the body. It is generally used for medicinal injection bottles, oral liquid bottles, etc.

In the early days, penicillin was often stored in vials, hence the name vial. Vial, also known as sodium-calcium glass molded injection bottle, is a small bottle sealed with a rubber stopper. It comes in brown, transparent, and other varieties, generally made of glass. The neck of the bottle is relatively narrow, and the thickness below the neck is consistent. The mouth of the bottle is slightly wider than the neck and slightly narrower than the body. It is generally used for iodine tincture bottles, injection liquid bottles, oral liquid bottles, etc.

Ampoule, also known as neck-breaking ampoule or injection bottle, is a sealed small bottle commonly used to store injectable drugs, vaccines, serums, etc., with a capacity generally ranging from 2ml to 20ml. The common type is for medical use, and ampoules are made from glass tubes, widely used to hold injectable formulations and high-purity chemical drugs that must be isolated from air. The neck of the ampoule is sealed with an open flame to isolate air, and the neck is marked; when pressure is applied, the neck will break to extract the liquid.

The difference between vials and ampoules is that ampoules are sealed as a single unit, while vials are sealed with a rubber stopper and are thicker than ampoules.
