Procuct

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

All kinds of products and different materials form a standardized system that weaves vertically and horizontally, which provides sufficient basis and conditions for choosing scientific, reasonable and suitable glass containers for all kinds of drugs. The selection and application of various types of drugs of different dosage forms, properties and grades to medicinal glass bottles should follow the following principles:

Good and suitable chemical stability principle

The glass containers used to contain all kinds of medicines should have good compatibility with the medicines, that is, ensure that certain substances between the glass containers cannot occur due to the instability of the chemical properties of the glass containers during the production, storage and use of the medicines. The chemical reaction causes the variation or failure of the medicine. For example, high-end medicines such as blood preparations and vaccines must choose glass containers made of borosilicate glass. All kinds of strong acid and alkali water injection preparations, especially strong alkali injections, should also use glass containers made of borosilicate glass. At present, the low borosilicate glass ampoules that are widely used in my country are not suitable for containing water injection preparations. This type of glass material should gradually transition to 5.0 glass material in order to meet international standards as soon as possible to ensure that the medicines it contains are in use Does not fall off, does not become turbid, and does not deteriorate.
