Ultra-low temperature freezers are specialized to achieve and sustain such low temperatures. To ensure dependable and consistent functioning, they are often built with heavy-duty insulation, high-quality materials, and modern refrigeration systems. The cascade refrigeration system, which uses two or more compressors in series to achieve ultra-low temperatures, is the most prevalent form of cooling system used in ultra-low freezers. These freezers also feature advanced temperature control systems that provide exact temperature settings, temperature fluctuation warnings, and data logging features for monitoring and recording temperature data over time.
Definition Of Ultra-Low Temperature Freezers
Ultra-low temperature freezers (ULT freezers) are complex refrigeration systems designed specifically to store and preserve samples at extremely low temperatures. They can reach and maintain temperatures as low as -86°C, well below the freezing points of water and most organic compounds. This extreme cold helps to prevent sample deterioration, enzyme denaturation, and other undesirable chemical reactions that may occur at higher temperatures, preserving the integrity and viability of samples for long-term storage.
