The device has a built-in foam layer and needs to be pre-injected with 250 ml of isopropanol before adding the cryogenic vials to ensure a rapid freezing rate of -1°C (-33.8°F) per minute. Through the programmed cooling process, the damage to the internal liquid of the cell caused by rapid freezing can be effectively avoided.
