Ultra low temperature (ULT) freezer is a special type of freezer designed to store biological, medical, and chemical materials at extremely low temperatures, typically between -40 ° C to -86 ° C (-40 ° F to -123 ° F). These freezers are crucial in various scientific and medical fields, where the preservation of sensitive materials is important.

The ULT freezer is an important tool in the fields of science and medicine, requiring precise and stable ultra-low temperature storage. They provide a safe and reliable environment for protecting valuable biological and chemical materials, ensuring their long-term survival and integrity.
