Ultra cold storage freezers are essential in various industries such as biotechnology, pharmaceuticals, and research. These freezers have a temperature range of -40°C to -150°C and are crucial for preserving valuable samples and materials.


In biotechnology, ultra cold storage freezers are commonly used to preserve DNA, RNA, and other biological samples. These samples can be used for genetic testing, research, and experimentation. Without ultra cold storage freezers, DNA and RNA samples would break down, making it challenging to complete experiments.


Pharmaceuticals require ultra cold storage freezers to preserve medicines, vaccines, and experimental drugs. These freezers maintain the potency and efficacy of healthcare products by preventing them from breaking down due to exposure to heat or moisture. Vaccines, in particular, require ultra cold storage to maintain their efficacy and prevent spoiling.


In research, ultra cold storage freezers are used to preserve valuable samples such as proteins and blood. These samples may be used for studies related to diseases such as cancer and diabetes. Experimentation involving cells and tissues also relies on ultra cold storage freezers to maintain their viability and functionality.

How Ultra Cold Storage Freezers Work

Ultra cold storage freezers operate on a principle known as the vapor compression cycle. They use a compressor to compress a refrigerant gas, which is then passed through a condenser. The condenser releases the heat generated during the compression process, causing the refrigerant to condense into a liquid. The liquid refrigerant then passes through an evaporator inside the freezer, where it absorbs heat, causing it to evaporate back into a gas state.

The evaporator absorbs heat from the interior of the freezer, which keeps the temperature low enough to maintain the ultra cold temperature range. The compressor then repeats the cycle by compressing the refrigerant back into a gas, and the process starts again. This cycle ensures that the freezer maintains a constant ultra cold temperature range.

In conclusion, ultra cold storage freezers are critical in various industries that require the preservation of valuable samples and materials. These freezers use the vapor compression cycle to maintain a constant ultra cold temperature range, preserving the potency and efficacy of products and samples. Understanding the importance of ultra cold storage freezers in biotechnology, pharmaceuticals, and research highlights their essential role in science and development.

How do Ultra Cold Freezers Work

Are you curious about how ultra-cold freezers work? These specialized freezers are designed to reach and maintain temperatures as low as -80°C (-112°F), making them essential for preserving biological samples, vaccines, and other temperature-sensitive materials.

Ultra-cold freezers work by using a compressor to remove heat from the inside of the freezer and expel it outside. The compressor circulates refrigerant, which absorbs heat as it evaporates inside the freezer and releases that heat as it condenses outside the freezer. This process creates a consistent flow of cold air inside the freezer that maintains the desired temperature.

Inside the freezer, the materials are stored in racks, drawers, or boxes that are designed to withstand extremely cold temperatures. Ultra-cold freezers also have insulation and a door seal to prevent any warm air from entering and affecting the temperature inside the freezer.

But maintaining such low temperatures requires a lot of energy. To keep energy costs low, some ultra-cold freezers are equipped with energy-saving features like vacuum insulation panels or eco-friendly refrigerants.

Overall, ultra-cold freezers are an invaluable tool for researchers, medical professionals, and other industries that rely on the preservation of temperature-sensitive materials. With their advanced technology and extreme temperatures, they can keep your samples safe and secure for years.
