ULT freezers are used in biobanking and pharmaceutical laboratories to store protein, DNA, antibodies, small molecules, enzymes and other samples critical for biological research. They store thousands of dollars in products, sometimes for years on end. Ultra-low temperature (ULT) freezers are essential to any lab environment, as they play a critical role in helping to ensure the safe storage of precious samples. Operating within the -50°C to -80°C range, ULTs are used to store a variety of analytes and products, from biospecimen samples to enzymes and drugs.
