a system allows for the safe , rapid , efficient recovery of a drug solution from sealed vials . the system is closed so that highly potent compounds can later be recovered and reworked without large investment in further engineering controls . the system includes three main components : a recovery device that holds sealed vials containing a solution , and provides means to access the contents of the vials ; a peristaltic pump that pumps solution out of the vials ; and a recovery tank that receives the pumped solution .
