Ampoule

From Wikipedia, the free encyclopedia

An ampoule (also ampule) is a small glass sealed vial which is used to contain or preserve a fluid.

[edit] Historically

Historically ampoules were used to contain a small sample of a person's blood after death, which was entombed alongside them in many Christian catacombs. It was originally believed that only martyrs were given this burial treatment, but many believe that it was a widely-practised tradition.

[edit] Modern usage

Modern ampoules are most commonly used to contain pharmaceutical hypodermic solutions. They are hermetically sealed by melting the thin top with an open flame, and are designed with a (1) scoring around the neck (2) break ring around the neck or (3) a small cut on the neck. When pressure is applied, the top will break off and the medicine can be reached.

After opening the ampoule, the solution is filtered to remove any glass fragments which may have fallen in the solution when the ampoule was opened.

[edit] Production

Ampoules are produced from tubing glass. Tubes are inserted in a carrousel and heat is applied. By applying the right amount fo heat and using gravity the shape of the ampoule is achieved. As a lot of parameters will influence the production process vision systems are introduced in the carrousel and on the end of the production line.
