The influence of the glass material of the ampoule on the quality of the injection

The encapsulation process of injections is subject to high temperature sterilisation, and injections are stored for a long period of time. The ampoules containing the injections are in direct contact with different liquids, which may affect each other, resulting in pH changes, precipitation, discolouration and flaking of the injections. Therefore, it is necessary to understand the composition, type and nature of ampoule glass in order to choose the right one.

Chemical stability of glass

The glass resistance to alkali flaking is an important product inspection standard for medical ampoule glass. When poorly chemically stable glass ampoules are used to contain alkaline (PH8-12) injectable solutions, flaking and cloudiness can occur due to erosion of the solution after autoclaving or long-term storage. Injections containing such detachments can cause serious damage to the health of the user and can even be life-threatening. Therefore, ampoules that are subject to debridement are absolutely forbidden in medical practice.

Neutral borosilicate glass for injectable pharmaceutical glass

At present, China has become the third largest pharmaceutical market in the world. In the global pharmaceutical market, in the absence of new drug research and development, pharmaceutical companies have been through the route of administration, target changes, expanding the indications as the direction of secondary research and development of drugs, pharmaceutical packaging material innovation has also become the focus of drug innovation competition. In recent years, several of the world's largest pharmaceutical packaging material manufacturers, represented by the United States Calcon, have been vigorously expanding their business in China, and the rise of China's pharmaceutical packaging material industry has become imminent.
