The Blood Bag Organizer has four removable trays in a sturdy acrylic holder that fits into most drawer-type refrigerators. It is designed so that the blood bags can be easily stored by type and Rh factor. It keeps the bags from coming into direct contact with the refrigerator shelf and thereby eliminates cold spotting. Each tray has a handle at both ends and holds up to eight blood bags. The trays may be purchased separately.
