    • A method and apparatus for optimizing the primary drying step of a lyophilization cycle of a biological or pharmaceutical material. In one aspect, the invention is a method for lyophilizing a material comprising the steps of calculating a designed primary drying cycle for the material based on a product temperature profile for the material and modifying both a chamber pressure and a shelf temperature according to a designed primary drying cycle during a primary drying step. In another aspect, the invention is an apparatus for lyophilizing a material according to a designed primary drying cycle comprising a computer-readable medium, a processor in electrical communication with the computer-readable medium, a chamber pressure module in electrical communication with the processor, and a shelf temperature module in electrical communication with the processor.
