Abstract: A system and a method for producing a quantified defined portions of powder from at least one biological material at cryotemperature is shown, comprising means for grinding the biological material deposited in at least one first vessel to the powder; means for loosening the powder resulting from grinding the biological material in the first vessel; means for positioning at least one first opening in the first vessel, and means for transferring the quantified defined portions of powder in a plurality of second vessels by using the first opening as a transfer way.
