  • Patent number: 11072446
    Abstract: A method of preparing a double chamber container is disclosed that includes filling a substance into the container, freeze-drying the substance therein, inserting a middle plunger in the container to form distal and proximal chambers, wherein the middle plunger seals the distal chamber from the proximal chamber and the freeze-dried substance is inside the distal chamber. The method includes filling a reconstitution medium in the proximal chamber, and sealing distal and proximal openings of the container. The method includes providing a holder having a seat and arranging the container in the seat in an upright position wherein a distal end side of the container extends downwardly and a proximal end side of the container extends upwardly. The container is arranged in the seat while the substance is filled, the substance is freeze-dried, the middle plunger is inserted, the reconstitution medium is filled, and the proximal opening is sealed.
