How to Specify an Ultra-Low Freezer for Lab
To more complex things like cells and tissues, biomolecules such as oligonucleotides and proteins have thermal sensitivity. Ultralow temperature (ULT) freezers must be utilized to keep these materials at -80°C so that they may be examined and characterized. Cryogenic freezers, which can maintain temperatures as low as -150°C, may be used to retain samples for long periods in some...
