Specification Guidelines for Scientific Refrigerators and Freezers Lab Refrigerator and Freezer Temperature Capability. Laboratory refrigerators typically operate from 2⁰C to 10⁰C and freezers from -10⁰C to -25⁰C although there are exceptions based on models. Low-temperature freezers again depending on models are available for temperatures to – 25⁰, -30⁰ and -40⁰C.Ultra-low temperature freezers can be set from -50⁰ to -86⁰C.ndercounter/Countertop Laboratory Refrigerators and Freezers. Undercounter, countertop and stackable lab freezers and refrigerators are great for saving space but are more susceptible to temperature fluctuations because of their size.

Your Questions Answered Answer: You should keep your freezer temperature at or below 0° F, says the U.S. Food and Drug Administration. At that freezer temperature, the growth of harmful bacteria will be halted — indeed, foods that are kept constantly frozen at 0°F or lower will keep safe indefinitely, notes the FDA. The best way to find out whether your freezer is cold enough is to use a freezer thermometer.

- Measuring Temperature. A thermometer should be used to check the temperature of the freezer. The thermometer should be placed near the front of the freezer and checked at least once a week to assure that the freezer is maintaining the proper temperature.reezers should maintain a temperature of 0 F, or about -18 C. This temperature will stop the growth of bacteria but will not kill it.

The Laboratory Freezer A freezer temperature range of –20 to –40 °C provides safe and stable storage conditions for many types of cells and reagents. The quality and suitability of the lab freezer, however, are often taken for granted when in reality the lab may be using an outdated or even a malfunctioning unit.ab freezers with auto-defrost. Temperature stability is one of the most important features of a laboratory freezer. The choice of a manual or auto-defrost freezer will depend on the stability needs of the samples stored inside.

Refrigerator The lower temperature lowers the reproduction rate of bacteria, so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F). A similar device that maintains a temperature below the freezing point of water is called a freezer. The refrigerator replaced the icebox, which had been a common household appliance for almost a century and a half. For this reason, a refrigerator is sometimes referred to as an icebox in American usage.

Set Your Ideal Freezer Temperature The ideal freezer temperature is 0 Fahrenheit (-18 Celsius) for storing food.And -10 Fahrenheit (-23 Celsius) is recommended when freezing food. The faster food freezes the smaller the ice crystals. The smaller the ice crystals the smaller the change in texture and better quality when thawed.deal Freezer Temperature. Setting the ideal freezer temperature is vital to keeping your food safe. Freezing food stops the growth of bacteria, it does not kill it. So if the temperature gets too warm bacteria can start to grow again. But your freezer does more than that.
