With regard to bulk lyophilization, fears include things like air classification and aseptic barriers for loading and unloading the unit, partial meltback, uneven freezing and heat transfer through the powder mattress, and the additional aseptic manipulations necessary to crack up the large cake. For bulk lyophilization, not like other sterile bulk functions, media problems may be done.
