When you hear scientific refrigeration, you probably picture a high-tech lab with mist swirling out of freezers, or a massive walk-in storing something obscure and highly valuable. And Honestly? You’re not far off…  

Scientific refrigeration isn’t just a fancy term, it is a critical part of research, medicine, and industrial processes and progress. In this article we are breaking down what scientific refrigeration is, where it is used and why it is absolutely necessary in today’s world.  

Scientific refrigeration refers to the precise control of temperature in specialized refrigeration systems that are used in laboratory, medical, pharmaceutical, and industrial settings. Unlike home refrigerators these units are engineered for stability, consistency, reliability, and regulatory compliance.  

These units don’t just keep things cold; they keep them precisely cold. What does that mean? It means tight temperature ranges, alarms, data logging, on board diagnostics and more to meet the strict protocols and standards of the industry.  

Wherever temperature sensitive materials need to be preserved, analyzed or stored safely is where this type of refrigeration is used. Some examples include: 

• Hospitals and Clinics – blood products, tissue, and pharmaceuticals  

• Laboratories – Vaccines, chemicals, reagents, specimens, samples 

• Universities and Research Centers- cell culture media, biological samples, serum and plasma, gene therapy materials 

• Biotech & Pharma – Clinical Trial Samples, stem cells, antibodies, cell therapy materials 

• Food and Beverage Labs – Enzyme activity samples, volatile compound samples, fatty acid and vitamin samples, microbial isolates 

Scientific refrigeration equipment is built for precisely maintaining temperature. Here is how those temperature ranges and equipment break down:

Types of Scientific Refrigeration Equipment

Scientific refrigeration equipment is built for precisely maintaining temperature. Here is how those temperature ranges and equipment break down:

+2°C to +8°C – Standard Laboratory Refrigerators

Purpose: Storing reagents, samples, medications, and vaccines 

Common Uses: Labs, pharmacies, hospitals, blood banks 

Equipment Examples: 

• Medical-grade refrigerators 
• Pharmaceutical refrigerators 
• Blood bank refrigerators 
• Chromatography refrigerators 

-20°C to -30°C – Standard Laboratory Freezers

Purpose: Long-term storage of enzymes, biologicals, and lab samples 

Common Uses: Research labs, clinics, diagnostics 

Equipment Examples: 

• Lab freezers 
• Flammable material storage freezers 
• Explosion-proof freezers 

-40°C to -50°C – Low-Temperature Freezers

Purpose: Extended preservation of biological samples and chemicals

Common Uses: Biotech, pharma, academic research

Equipment Examples: 

• Low-temperature chest or upright freezers 
• Specialized storage for volatile compounds 

-70°C to -86°C – Ultra-Low Temperature (ULT) Freezers

Purpose: Storage of RNA, DNA, vaccines, cell cultures, and viral specimens

Common Uses: Bio-repositories, genomics, hospitals, vaccine distribution

Equipment Examples: 

• ULT freezers 
• -80°C upright or chest freezers 
• Vaccine freezers for mRNA storage (like COVID-19 vaccines) 

-150°C and Below – Cryogenic Freezers & LN2 Storage

Purpose: Long-term cryopreservation of cells, embryos, and genetic material 

Common Uses: Fertility clinics, biobanks, stem cell research 

Equipment Examples:

• Cryogenic freezers 
• Liquid nitrogen (LN2) storage tanks 
• Vapor phase LN2 freezers
