Blood Bag Organizers have four removable trays in a sturdy acrylic holder that fits into most drawer-type refrigerators. The organizer was designed so that blood bags can be easily stored by type and Rh factor. In addition, it keeps the bags from coming into direct contact with the refrigerator shelf. Each tray has a handle at both ends and holds up to eight blood bags. Trays may be purchased separately. Each tray is made of sturdy, clear acrylic. Two- and four-compartment trays may be used separately or used in the organizer. May be used in blood bag holder S1389-3.
