Lyophilization, or freeze-drying, is a process in which liquid materials are
slowly frozen in a vacuum, thereby removing water by maintaining a very low water
vapor pressure.
Lyophilized products are easily rehydrated and the activity or volatility
of the dried product remains stable until rehydration occurs.
Lyophilization has become a popular process for drying diagnostic
and pharmaceutical products. Freeze-drying is also commonly used
in food processing and in many industrial applications.
EMD Chemicals offers lyophilization capabilities in a wide variety
of batch sizes. Your product can be freeze-dried in a vial as a
finished product or in bulk and custom packaged. Lot sizes of finished
vials can range from several hundred to tens of thousands depending
upon the size of finished goods container. |
