How Refrigerators and Freezers Works In Laboratory?

Lab freezers have essential functions which are basically used to cool or freeze samples for preservation. Commonly, lab refrigerators are used to store samples at a temperature between - 5 and 15 degrees Celsius, while lab freezers normally store samples at a temperature between - 25 and - 15 degrees Celsius. Lower temperatures are gradually used to store biological samples, chemical vaccines, and bio molecular substances in laboratory freezers. If you need really low temperature in laboratory then go for Cryogenic freezing equipments. Other low temperature freezers are known as dual compressor cascade type which generally freezes up to -50 degrees at full speed.
Lab refrigerator and freezers are working on dual compressors, first compressors is used to freeze approx -40 C and second compressor needs to achieve the lower temperature before things gonna burst up. The adverse of using these freezers are they create more heat into the room and fans are noising, also more expensive to repair than a standard laboratory refrigerator or freezer if the compressor needs to be replaced or repair but Bergen refrigeration is one of the companies which provide commercial refrigeration repair on sale.
