Abstract: The present invention relates to a method for collecting and preserving biological specimens, such as human and animal tissues, cell types and subcellular materials for biobanking cryopreservation, comprising the steps of i) placing said specimen in a cooling fluid pre-set at a first predetermined temperature of between ?10° C. and ?60° C. for snap freezing—i.e. rapidly freezing—the specimen, and ii) reducing the temperature of said cooling fluid to a second predetermined temperature suitable for preserving said specimen. The reduction of the temperature in step ii) is performed by a predetermined cooling profile.
