Article: Walking on Thin Ice - Controlled Freezing & Thawing of APIs

Read Single Use Support's article, published on Cell & Gene Therapy Insights, why it is important to adapt both freezing and thawing processes to the characteristics of the protein or active pharmaceutical ingredient for cold chain storage and shipment. Controlled freezing and thawing facilitates consistent product quality during the fluid management processes involved in manufacturing.

Efficient freezing and thawing of vaccines with single-use technologies

The global distribution of any medical substance requires more than what meets the eye. Before a vaccine can finally be shipped, it needs to be safely processed and contained. Single use technologies offer a number of advantages that cover the entire biopharmaceutical process, including development, manufacturing and logistics.
