Controlled rate freezing
The processed cord blood units are first gradually frozen using a controlled-rate freezer to lower their temperature to -90°C before they can be transferred into the liquid nitrogen tanks (-196°C) for long-term storage. The programmed freezing procedure helps maintain the viability of the stored stem cells.

To enhance the safety and security of the storage facilities, advanced computerized security systems have been deployed, including fingerprint door locks, smoke sensors, oxygen content monitors, 24-hour liquid nitrogen level monitoring and alarm system and infrared alarm system.

In order to evaluate the storage stability of cord blood products, the cryopreserved cord blood units in public bank are randomly selected and thawed to test the viability and recovery rate of cells every month.
