Medicinal glass refers to glass specially used for medicine packaging, generally refers to glass bottles and utensils. According to the glass material, it can be divided into soda lime glass and borosilicate glass. According to the manufacturing process, it can be divided into molded bottles, controlled bottles, and ampoules. Chemical performance is one of the important criteria for measuring the quality of pharmaceutical glass, and the most important parameter is the linear thermal expansion coefficient. Whether the long-term storage of medicines will reflect the glass. According to the coefficient of linear thermal expansion, there are corresponding classifications of medicinal glass

Advantages and applications

Good and suitable resistance to sudden changes in temperature

Different formulations of medicines must undergo high-temperature drying, disinfection and sterilization, or low-temperature freeze-drying processes during the production. This requires glass containers to have good and appropriate resistance to temperature changes without bursting. The resistance to rapid temperature change of glass is mainly related to the coefficient of thermal expansion. The lower the coefficient of thermal expansion, the stronger its ability to resist temperature changes. For example, many high-end vaccine preparations, biological preparations and freeze-dried preparations should generally use 3.3 borosilicate glass or 5.0 borosilicate glass. When the low borosilicate glass produced in large quantities in China undergoes drastic changes in temperature differences, it is often prone to explosions and bottle bottoming. In recent years, my country’s 3.3 borosilicate glass has developed greatly. This type of glass is particularly suitable for freeze-dried preparations because its resistance to sudden changes in temperature is better than 5.0 borosilicate glass.
