10.75-22.50mm Transparent Borosilicate Glass Tube For Medicinal Use

Procuct

Pharmaceutical glass refers to the specialized glass for drug packaging, generally refers to glass bottle and utensils. According to the material can be divided into sodium calcium glass and borosilicate glass. According to the manufacturing process, it can be divided into molded bottles, controlled bottles and ampoules. Chemical properties are one of the important criteria for evaluating the quality of medicinal glass, among which the most important parameter is the coefficient of linear thermal expansion. Medicines stored for a long time will reflect glass. According to the linear thermal expansion coefficient, medicinal glass has a corresponding classification

Advantages and applications

It has good resistance to abrupt change of temperature

Production of different dosage forms of drugs, must go through high temperature drying, disinfection sterilization, or freeze drying at low temperature. This requires the glass container to have good and appropriate resistance to temperature changes without bursting. The heat resistance of glass is mainly related to the coefficient of thermal expansion. The lower the coefficient of thermal expansion, the stronger the resistance to temperature change. 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. 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.
