A system for storing a plurality of cryopreservable samples is provided, comprising a liquid nitrogen Dewar flask having a substantially circular opening of diameter X defined therein, the Dewar flask containing therein a plurality of Dewar flask-compatible storage racks, each storage rack comprising at least one substantially rectangular container, having a first set of opposite sides in substantially perpendicular relationship with a second set of opposite sides, the first set of opposite sides and the second set of opposite sides defining an inner space therebetween, and a plurality of strips, located in the inner space and each in contact with at least one side, formed in substantially parallel relationship with the first set of opposite sides, the plurality of strips forming a plurality of storage slots in the inner space, wherein at least one of the plurality of storage slots contains a cassette containing therein a cryopreservable sample. The plurality of storage racks are arranged in the Dewar flask such that a circle intersecting at least two of the plurality of storage racks located in the Dewar flask has a diameter which is greater than the diameter X of the opening. A method of storing cryopreservable samples is also provided.
