Cryobank
A cryobank (from ancient Greek κρυος (kryos) = frost , ice ) is the place where biological material is stored, such as B. stem cells , with the help of cryopreservation and is a special form of the biobank . From a technical point of view, a cryobank consists of a cryocontainer and the biosamples stored in it and packed in substrates . The cooling to at least –140 ° C is carried out using liquid nitrogen ; the samples themselves being stored in the gas phase. In modern cryogenic containers, a suitable low-temperature supply with its introduction and discharge devices ensures that a storage temperature of –140 ° C is always guaranteed and that the cryogenic container is prevented from icing up through built-in locks. With the help of cryotechnology an attempt is made to reduce a number of processes such as B. to automate the freezing or thawing process and thus to increase the quality of storage and the throughput of samples.
In 2005 German cryobanks merged to form the Association of German Kryobanks .
