20ml 25ml Neutral Borosilicate Injection Vials
Medicinal glass is in direct contact with drugs, and the chemical stability, strength and barrier performance requirements are higher than ordinary glass. Medicinal glass should have good water resistance, acid resistance, alkali resistance and other characteristics. At present, borosilicate glass is mainly used.
The acid and alkali resistance of borosilicate glass belongs to the first class, and the quench and heat resistance is strong. The chemical stability, mechanical strength and impact resistance of borosilicate glass are better than other glass. In addition, as a drug package, long-term contact with liquid medicine and blood will not precipitate, which can effectively protect the chemical properties of drugs and health food.
