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

It has good resistance to abrupt change of temperature

Different dosage forms of drugs must be produced through high temperature drying, disinfection and sterilization or low temperature freeze drying. This requires glass containers to have good and appropriate resistance to temperature changes without bursting. The heat resistance of glass is mainly related to thermal expansion coefficient. The lower the coefficient of thermal expansion, the stronger the resistance to temperature change. For example, many high-end vaccine preparations, biologics, and freeze-dried preparations should generally use 3.3 borosilicate glass or 5.0 borosilicate glass. The low borosilicate glass produced in large quantities in China is prone to explosion and bottle bottom phenomenon when the temperature difference changes sharply. In recent years, China's 3.3 borosilicate glass has a greater development. This glass is particularly suitable for use in freeze-dried preparations as it is more resistant to sudden changes in temperature than 5.0 borosilicate glass.
