A method for cryopreservation of biological material where a sample of a biological material is inserted into a packaging having two substantially parallel walls spaced from 2.5 mm apart or less, the walls connected to each other along a substantially part of their periphery and including a plurality of internal ridges for directing the flow of material through the packaging. After the material is evenly distributed in the package, the material is frozen for cryopreservation of biological material. |
