Do I need MDR liquid nitrogen?
It depends on your application. If it involves the storage of human tissue samples the chances are that you do. This includes any applications that use liquid nitrogen for preserving blood and bone marrow cells, sperm, ova, early embryos, and, in the microbiology laboratory, a variety of microorganisms (bacteria, fungi, etc)
Another application that requires MDR liquid nitrogen is cryotherapy, which refers to the focal application of extreme cold for the in-situ destruction of abnormal or diseased tissue.
