摘要:
A device for cryoprotecting thermolabile products. A container (20) receives an annular rack (40) which is sealed by an enclosure (60). The enclosure (60) includes an outer stationary toroid (70) and a rotatable core (90). A robotic arm (160) is adapted to move and is supported by the core (90). The robotic arm (160) accesses an interior of the enclosure (60). An access portal (80) allows removal and placement of thermolabile products constrained by a holder (150). The robotic arm (160) accesses product and holder (150) and embarks upon controlled freezing of the product and its location in the rack (40) until subsequent retrieval. A computer controls the rate of freezing and stores in memory the location of all of the stored products. The robotic arm (160) reads the product in storage to assure the correct product is being accessed.
摘要:
A bag (10), method of manufacture and process are disclosed for the cryopreservation of thermolabile substances. The bag is characterized as having substantially uniform thickness throughout its length and height. The bag features a radiused peripheral edge wall (4) for stress relief and to provide the constant cross section. A peripheral flashing circumscribes the radiused edge wall and provides a suitable purchase area for sealing, so that the thus formed bag is less susceptible to fracture particularly when exposed to cryogenic temperatures. The uniform thickness of the bag promulgates uniform heat transfer to and from the contents of the bag in relation to any surrounding medium at a different temperature. The bag affords more space for efficient storage and reduces heat invasion into the contents of the bag when a plurality of bags are placed, with their larger planar surfaces, in contact with each other.

摘要:
A system and method for controlled rate freezing and storage of thermolabile substances. The system includes a storage unit (20) for receiving product stored within a bag (180) and an overlying protective canister (110) associated with a robotic arm (60) and reading device which places the canister (110) in the preserving environment. A control system, driven by a computer, monitors the ingress, egress and storage location and particularized profiles of the articles being placed in storage.
