The BD PhaSeal™ System pioneered the category of closed-system drug transfer devices (CSTDs) to help protect the pharmacists and clinicians who prepare and administer hazardous drugs. 20 years later, we turned to healthcare professionals like you for feedback and guidance to optimize its every component. The result is the BD PhaSeal Optima System—a next-generation, user-tested CSTD solution that advances hazardous drug safety.
