The Hidden Key to Effective Freeze Drying: The Freezing Step

Understand the impact of ice crystals and supercooling for improved drying results.

Video Description

The freezing step was overlooked for years, but it is of crucial importance in freeze-drying. How pure ice crystals grow determines the porosity of the dried cake and thus has a significant influence on primary drying.

In this video, we highlight the key aspects for better understanding the freezing step. We explain the importance of pure ice diagrams and tabulated data for the freeze-drying scientist.

Ice nucleation and supercooling temperatures are also introduced.
