It can be quantitatively... WebInstead of forming eutectics, the entire suspension becomes increasingly viscous as the temperature is lowered. Finally the product freezes at the glass transition pointforming a vitreous solid. This type of product is extremely difficult to freeze dry. Primary drying: Several factors can affect the ability to freeze dry a frozen suspension.
