ULT freezer

A standard upright negative 80 degree freezer

An ultra low temperature (ULT) freezer is a refrigerator that stores contents at −80 to −86 °C (−112 to −123 °F).[1] An ultra low temperature freezer is commonly referred to as a "minus 80 freezer" or a "negative 80 freezer", referring to the most common temperature standard.[2] ULT freezers come in upright and chest freezer formats.
