Zusammenfassung:A method and apparatus for eliminating or minimizing the non-uniformity of edge vials compared to center vials during freezing or primary drying of product therein in a freeze dryer. A temperature controlled surface is positioned in close proximity to or in contact with the edge vials to control the temperature thereof. The method and apparatus may be used to simulate in a development freeze dryer the conditions of the center and edge vials in a larger batch target freeze dryer.
