FRYKA freezers are used in molecular biology laboratories for example. In addition to cryopreserved microorganisms of a strain collection, a DNA genome library can be stored. Particularly useful from the user's point of view is the fact that, as a compact desktop unit, the cold box can be placed directly in the laboratory, avoiding a lenghty trip to outsourced large freezers. Also the samples do not need to be cooled for transport to the laboratory.
In a cell culture laboratory, a -80°C freezer was used for sensitive cells, such as mammalian cells, to freeze them under controlled conditions. Sensitive proteins such as antibodies or cytokines are stored in these devices to guarantee the long life and activity of the proteins.
