Pharmaceutical glass has more advantages over other material.Glass is defined like this in the pharmaceutical field:it has good chemical stability,heat-resistant stability,certain mechanical strength,and also has series of physicochemical property like brightness cleanness,transparency,easiness for cleaning and sanitizing,good capability of sealing,etc.
 

Injection vials made of borosilicate glass tubing,because of its ideal hydrolytic resistance,resistance to thermal,shock,freeze,acid and alkali and its outstanding tolerance,is the first choice of pharmaceutical packaging for biologics,lyophilization,vaccines and blood preparation.Low borosilicate injection vials have boron trioxide content of 5-8%, so have good chemical stability and resistance to shock ,is the first choice of pharmaceutical packing for water injection and powder injection.

Neutral borosilicate injection vials have boron trioxide content of 8-10%, so have good chemical stability and resistance to shock , is the first choice of pharmaceutical packing for biologics, lyophilization, vaccines and blood preparation.
