Cryogenic freezers, also known as ultra-low temperature freezers, are specialized freezers designed to maintain extremely low temperatures, typically around -196 degrees Celsius. They are used in a wide range of applications, including biomedical research, pharmaceuticals, and the food industry. In this blog, we will explore some of the common uses of cryogenic freezers.
Biological samples and tissue preservation
Cryogenic freezers are widely used in biological research and medical applications for the preservation of biological samples and tissues. They are used to store specimens such as blood, serum, and tissue samples for long periods, sometimes up to decades. Cryogenic freezing helps to prevent the degradation of biological samples by halting metabolic processes and preserving the integrity of the material. Cryogenic freezers are especially useful for the storage of stem cells, which can be used for a variety of therapeutic applications.
Pharmaceutical storage
Cryogenic freezers are used in the pharmaceutical industry for the storage of vaccines, drugs, and other medical products. Maintaining low temperatures is critical for the preservation of these products and ensuring their efficacy. Cryogenic freezers are often used for the long-term storage of pharmaceuticals, as they can maintain stable temperatures for extended periods of time.
Food industry
Cryogenic freezers are also used in the food industry for the preservation of frozen foods. The extremely low temperatures achieved by cryogenic freezers help to preserve the quality of frozen foods by slowing down bacterial growth and preserving the texture and flavor of the food. Cryogenic freezers are also used in food processing, such as the quick freezing of fruits and vegetables to preserve their nutritional value.
Aerospace industry
Cryogenic freezers are also used in the aerospace industry for the storage of rocket fuels and other materials used in space exploration. Cryogenic fuels such as liquid oxygen and liquid hydrogen are used in rockets because of their high energy content, and they must be stored at extremely low temperatures to remain in a liquid state. Cryogenic freezers are used to maintain the temperature of these fuels during storage and transport.
Material testing
Cryogenic freezers are also used in material testing and engineering applications. The extreme cold temperatures can be used to test the strength and durability of materials such as metals and polymers, and to evaluate their behavior under different environmental conditions.
Forensic science
Cryogenic freezers are used in forensic science for the long-term storage of DNA and other biological evidence. The extremely low temperatures achieved by cryogenic freezers help to preserve the integrity of biological evidence and prevent the degradation of DNA samples over time.
Cryogenic freezers are versatile tools with many important applications. They are used in a wide range of industries, including biomedical research, pharmaceuticals, food processing, aerospace, and material testing. Cryogenic freezing is an essential technology for the preservation of biological samples, pharmaceuticals, and other materials that require long-term storage at low temperatures. By maintaining stable and consistent temperatures, cryogenic freezers play an important role in ensuring the integrity and efficacy of these materials.
