Ultra-low freezers are designed to maintain extremely low temperatures, typically ranging from -86°C to -20°C, for the long-term storage of sensitive biological samples, vaccines, and other temperature-sensitive materials. The reliability of an Ultra-Low Temperature Freezer (ULT) is dependent on its ability to maintain the temperature- sensitive specimens it needs to store at their intended temperature.

Whenever water vapor meets the cold interior surfaces of a ULT, frost can build up inside the device, which is merely the nature of extremely low-temperature surfaces in the presence of humidity. However, this can lead to performance issues leading to unsatisfactory customer experiences. In this paper we will explore what the problems that can arise due to this phenomenon are and how technologically advanced designs and features of B Medical Systems’ Ultra-Low Freezers can provide a solution.
