1. An apparatus for eliminating or minimizing non-uniformity of edge vials compared to center vials during freezing and/or primary drying of product therein in a freeze dryer, comprising:
a temperature controlled surface surrounding both the edge vials and the center vials, wherein the temperature controlled surface is positioned in direct contact with or direct connection to the edge vials, or connected to the edge vials via a thermal conductor, to control the temperature of the edge vials, the temperature controlled surface is closer to the surrounded edge vials than the surrounded center vials,
wherein the non-uniformity of the edge vials compared to the center vials during freezing and/or primary drying of product therein in the freeze dryer is reduced by adjusting the temperature of the temperature controlled surface.
