About Lyophilization

Lyophilization (or freeze-drying) is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport and storage. Pharmaceutical companies often use lyophilization to increase the shelf life of products, such as vaccines and other injectables. By removing the water from the material and sealing the material in a vial, the material can be easily stored, shipped, and later reconstituted to its original form for injection.
