A ampoule (also an ampoule , ampoule , or ampulla ) is a small bottle of bottle used to hold and store samples , usually solid or liquid. Ampoules are generally made of glass, although plastic ampoules exist.
Modern ampulists are most often used to contain medicines and chemicals that must be protected from air and contaminants. They are sealed by melting the thin top with an open flame, and usually open by breaking the neck. If done correctly, this last operation creates a clean break without extra broken glass or slices; but the liquid or solution can be filtered for greater assurance. Glass particle contamination continues to be of concern, with patients receiving parenteral drugs, such as care under hospital care, are at greater risk of receiving glass particulates when the drug is aspirated. Space above chemicals can be filled with inert gas before sealing. Ambulatory glass walls are usually strong enough to carry into the glovebox without difficulty.
Glass ampules are more expensive than bottles and other simple containers, but there are many situations where their superior resistance to gas and liquids and interior surfaces worth a surcharge. Examples of chemicals sold in ampoules are injectable drugs, air sensitive reagents such as tetrahis (triphenylphosphine) palladium (0), hygroscopic materials such as deuterated solvents and trifluoromethanesulfonic acid, and analytical standards.

Historical amphet
Historically ampoules were used to contain a small sample of a person's blood after death, which was buried beside them in many Christian catacombs. Initially it was believed that only the martyrs were given this funeral treatment, although it was thought to have become a widely practiced tradition.
San Gennaro
An ampoule, presumably dating from 305 and filled with the blood of Saint Janus ( San Gennaro ), the bishop of Benevento, has been kept for centuries at the Cathedral in Naples. Every year on September 19th the city celebrates San Gennaro's Feast, when the content of solid reddish-brown ampoules usually melts after being taken from a safe, taken in a procession and placed on the cathedral altar.
Sainte Ampoule
Another famous Ampul is the Holy Ampulla ( Sainte Ampoule ) that holds the anointing oil for the coronation of the king of France. The oil is allegedly derived from the Clovis I; it was kept for a while at the tomb of Saint Remigius and later at Notre-Dame Cathedral, Reims. It was used in the coronation of Charles X.

Production
Modern glass mirrors are manufactured industrially from short long glass tubes, formed by heating with gas torches and gravity in automated production lines. Computer vision techniques are commonly used for quality control.
Filling and sealing of ampoules can be done by automated machines on an industrial scale, or by hand in small scale industries and laboratory settings. Empty amuls can be purchased from the scientific glass supply house and sealed with a small gas torch. It forms a membrane that allows one to reverse the open ampoule without spilling. The Schlenk line can be used to seal under an inert atmosphere.
Other uses
Ampul is a common practice as a container of low frequency RFID tags. It is used primarily for marking animals, such as dogs for identification.
Ampoule code
Ampuls often have colored rings of paint or enamel around their necks. Modern ampule color codes are performed during the manufacturing process. The machine painted a colored ring on the ampoule shortly after being sealed. Rings are made of substances that can be read by other machines. This color code identifies the substance inside the ampoule so it does not need to be tested to verify its contents. Machine readable color codes allow for accurate handling of substances for storage, labeling, and secondary packaging.
The dot above the neck identifies the location of small pieces on the glass to help break/open the ampoule.
