Abstract
A biopharmaceutical material cryopreservation system is provided that includes a flexible sterile container comprising a biocompatible polymeric material. The flexible sterile container contains biopharmaceuticals materials for freezing and cryopreservation. A freezing system is thermally coupled to the biopharmaceutical materials via the flexible sterile container. The freezing system comprises a temperature sensor that monitors a temperature of the biopharmaceutical materials. Also, the freezing system comprises a feedback loop constructed to control a dendritic freezing front velocity, within the biopharmaceutical materials, in a range from approximately 5 millimeters per hour to approximately 250 millimeters per hour based on feedback information from the temperature sensor.
