Storage

The transplant storage period aims at a long duration (throughout the life of the child) and the storage method is an important step.

Currently, storage is possible in Romania (Cluj, Bucharest) and in Slovakia. These storage facilities are located and constructed so as there should be no danger of damage by floods, earthquakes, etc..
Also for security reasons, the location of deposits was chosen in areas with the lowest crime rate. Against vandalism, the storage facilities are secured by alarm systems and closely supervised.

Transplants are deposited in biological containers with liquid nitrogen refill. The vapours released from nitrogen keep the inside of the container at a temperature of about -196 ° C. This system is absolutely independent of any power source or other form of energy. The amount of nitrogen in the container and the temperature are controlled by the monitoring system that immediately signals any malfunctions.

This system, together with other electronic security systems, has at its disposal a secondary source of electrical power. This means that power outages do not affect the temperature in the containers or the safety of the monitoring systems.
Moreover, the condition of the liquid nitrogen in the containers is controlled at regular intervals by the designated staff. Liquid nitrogen is filled from tanks. These, in turn, are filled by the liquid nitrogen supplier.

The transplant itself is tightly closed and cannot be infected. Each transplant is preserved first in quarantine to confirm the sterility the harvested samples and only after that it is definitely stored. Bacterially or mycologically contaminated blood samples, will be kept in the same conditions of cryopreservation in liquid nitrogen, at - 196 Celsius degrees, as the sterile samples, but in separate quarantine containers.
