Lyophilization stopper

Our lyophilization stoppers are specifically designed for pharmaceutical applications that require lyophilization (freeze-drying). These stoppers, available in sizes like 20mm and 13mm, are made from high-quality materials such as bromobutyl and chlorobutyl, which can withstand the extreme temperatures during the freeze-drying process. They provide excellent sealing and protection against contamination and moisture. For added protection, the stoppers can be coated with Flurotec®, preserving product integrity throughout the production process. APG Europe’s lyophilization stoppers are compatible with crimp-neck vials and are available in both standard and sterile packaging.
