A Bio-freezer is a kind of a equipment where laboratory expert can store biological samples which can easily handle freezing like Bacterial cells, plasmid DNA, Proteins, and the likes. Basically, this Bio-freezer has been designed for freezing biomass or cell-suspensions in the lab, pilot and huge scale biotechnology under sanitary and biosafe conditions. Each one of these can be stored for n number of weeks to months in a -20C Freezer, and can be stored for many years in a -80C Freezer. However, microbiology laboratories will also keep glycerol stocks in freezers that are cell lines, which are stored in a small sum of glycerol to help keep them from dying. These Bio Freezer are highly required as most of the proteins are quite fragile and sensitive to heat, and they are precious as well.
