Daikyo Crystal Zenith® – The Clear Advantage in Pharmaceutical PackagingGlass-like transparency and superior packaging attributes make Daikyo Crystal Zenith the ideal choice
for packaging oncology drug products, products that react with glass, and freeze-dried or protein-based products.
Manufactured by West’s partner in Japan, Daikyo Seiko, Ltd., the Crystal Zenith polymer has low moisture permeability and extractables, and high resistance to temperature and breakage.
Vials for Lyophilized Drugs
Glass pharmaceutical vials are made to withstand the stress of lyophilization. Tight manufacturing controls achieve a consistently flat base to maximize shelf contact within the lyophilization chamber.
Vial Blowback Feature
Glass vials are engineered with a blowback feature – a circular depression in the crown – to prevent the stopper from dislodging. Many West stoppers have a corresponding locking characteristic that works in tandem with the vial.
