Application Scenarios of Pharmaceutical Glass Bottles

1. Injectables 
Borosilicate glass (Class I): 
It is used in biological products (such as vaccines, monoclonal antibody drugs), chemical injections (such as antitumor drugs, antibiotics), because of its corrosion resistance, it can avoid the reaction between drugs and glass, and guarantee the efficacy of the drugs.
Example: New Crown Vaccine adopts high borosilicate glass vials to ensure the stability of vaccines in storage and transportation.
Low borosilicate glass (Class II): 
is used for general injections (e.g. glucose injection, saline), which is cost-controlled and meets the basic temperature resistance requirements.
2. Oral and topical preparations 
Calcium sodium glass (Class III): 
Packaging bottles for oral solid preparations (e.g. aspirin tablets, fish oil capsules), with lower requirements for chemical stability, focusing on cost and practicality.
For external preparations (e.g. povidone-iodine bottles, alcohol cotton ball bottles), good sealing is required to prevent volatilization.
Brown glass: 
Used for photosensitive oral drugs (e.g. vitamin B12 tablets) to avoid drug failure due to light exposure.
3. High-end preparations and special scenarios 
Lyophilized bottles: 
Used for lyophilized biological drugs (e.g. recombinant protein drugs), which need to withstand the lyophilization cycle of - 40℃~60℃, and are mainly made of borosilicate.
Pre-filled glass syringes: 
Used for self-exempted diseases, diabetes and other drugs that require frequent injections (e.g. insulin refills), to facilitate the patient's self-administration and reduce the risk of contamination.
