Classification: CPC F | IPC F

Claim 6:
7. An apparatus for enabling a development freeze dryer containing a small sample of product in vials to simulate freezing and sublimation conditions of product in vials in a larger batch target freeze dryer, comprising:
a temperature controlled surface surrounding both outer edge vials and center vials, wherein the temperature controlled surface is in direct contact with or direct connection to outer edge vials in the development freeze dryer, or connected to the outer edge vials via a thermal conductor, the temperature controlled surface is closer to the surrounded outer edge vials than the surrounded center vials,
wherein conditions of center vials and/or outer edge vials of the larger batch target freeze dryer can be simulated by adjusting the temperature of the temperature controlled surface.
