Lyophilizate Analytic

Lyophilization involves freezing a substance at extremely low temperatures and then extracting liquid via sublimation, thereby transforming solid water into gaseous water. This process is able to extend the shelf life of heat-sensitive drugs while preserving its 3D structure and integrity and to make the material more convenient for transport. Also, the process is a modern alternative for cryopreservation in the case of cells and tissues. STEMart offers lyophilizate analytic services for antibodies, cell and gene therapies, vaccines and other biologics to characterize the appearance and structural state of the freeze-dried powder, the reconstitution time and behavior, the residual moisture in the headspace and of the freeze-dried powder, the specific surface area, as well as glass transition temperature of the freeze-died amorphous product.
