BD® PhaSeal™ Protector P21, for Vial Pressure Equalization, Sterile, 20 mm
PhaSeal is a system for the safe handling of hazardous drugs. As a clinically proven closed-system drug transfer device (CSTD), it has been proven to prevent hazardous drug exposure from preparation and administration to waste disposal. The Protector P21 is a pressure equalization device, permanently attached to the vial used in the preparation of drugs from either powder or liquid form. The Protector provides closed pressure equalization through the sealed expansion chamber and dry connections via the double membrane technique. This ensures that there is neither overpressure nor vacuum when air or fluid is injected into or aspirated from the vial. When attached to a vial, Protector 21 has an equalizing capacity of 20 mL of air.
