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.
