Laboratory Grade Refrigerators and Freezers


Laboratory grade refrigerators and freezers are products used specifically for storing non-volatile reagents and biological specimens in laboratory settings, including hospitals, clinics, university and government research laboratories, and pharmaceutical manufacturing plants. They are designed to contain chemicals or biological specimens at stable, low temperatures.

The ENERGY STAR label will appear on laboratory grade refrigerators and freezers across a range of product types and sizes, allowing customers to purchase efficient products right sized and properly controlled for their sample needs. ENERGY STAR laboratory grade equipment can reduce energy consumption and lower utility bills through the use of technologies such as more efficient cooling compressors, advanced microprocessor temperature control and defrost sensors, more efficient high-capacity air circulation systems, and innovative refrigerants.

Eligible Products:

  • General purpose laboratory grade refrigerators
  • High performance laboratory grade refrigerators
  • General purpose laboratory grade freezers
  • High performance laboratory grade freezers  
  • Ultra-low temperature freezers

Ineligible Products:

  • Commercial refrigerators and freezers

What should I look when buying a laboratory grade refrigerator and freezer?

Purchasing ENERGY STAR certified laboratory grade equipment will help reduce medical facilities’ costly energy bills, while ensuring the safe storage of a variety of chemicals and specimens.

Consider selecting lab grade refrigerators and freezers with a lower Global Warming Potential refrigerant. Refrigerants with lower global warming potential (GWP) for lab grade refrigerators and freezers include R-744 (CO₂), R-290, and R-170. Selecting an ENERGY STAR certified model with a lower GWP refrigerant means your product will have a much lower impact on the climate if the refrigerant is released into the environment. The GWP compares the warming power of a substance to an equivalent amount of CO2 (GWP = 1 for CO2). Some refrigerants are hydrofluorocarbons (HFCs), which are powerful greenhouse gases with GWPs hundreds or thousands of times higher than CO2. Find lab grade refrigerators and freezers that contain refrigerants with a lower impact on global warming here.
