Xemed has delivered one XeBox xenon polarizing system to the University of Pennsylvania. The research group led by Dr. Rahim Rizi accepted the polarizer upon independently confirming polarization over 48% at a flow rate of 4.5 liters of xenon per hour. Xemed’s XeBox is fully automated, controlled by the end-user through a touch-screen interface for selecting the batch volume, xenon type (natural or isotopically-enriched), and xenon flow rate. After the end-user attaches the desired combination of Tedlar bags (0.25L, 0.5L, 0.75L, 1.0L) onto the four ports, the system can produce up to 3 liters in one batch. Options for xenon flow rates are “slow” (3 liters/hour), “medium” (4.5 liters/hour), or “fast” (6 liters/hour). The MagniXene® contrast agent and XeBox polarizing system, operated with Xemed-supplied 129Xe, connectors, and bags, are recognized by the FDA as a medical drug-device combination.
