What is a Ultra low temperature freezer?

Freezer that can be stored at ultra-low temperatures. Stable storage for a longer period is possible compared to storage at -20 ° C. The definition of ultra-low temperature varies from manufacturer to manufacturer, but it is generally -50 to 60 ° C or less for commercial use. For research use, -80 ° C freezer is applicable. Unlike ordinary household freezers, the ultra-low temperature freezer used in laboratories is a deep type called a chest type and is taken in and out from the top. It is also called a deep freezer because of its shape. Used for freezing storage of fresh fish such as tuna, storage of cells, reagents, and specimens.

Application of Ultra low temperature freezer

It is used for research purposes (storage of cells, specimens, reagents), long-term storage of fresh fish (tuna, bonito, etc.), storage of dry ice, etc., which requires storage of freshness under more severe conditions, but is used for freezing storage. At the laboratory level, refrigerate or -20 ° C storage is used for short-term storage of general reagents, and -80 ° C storage is used for long-term storage. Other certain vaccines and medicines (raw materials) should be stored at -80 ° C until the start of use in order to extend the storage period. It is also essential for program freezing such as cell freezing.
