When you go to the lab, to take something to get tested, you can see that there are some refrigerators and freezers that they use for keeping biological or another kind of samples that has to be kept on cold.
Lab freezers have an obvious and crucial function. They are used to cool or freeze samples, to protect them. The difference between refrigerators and freezers is that refrigerators are used to store samples at a temperature between -5 and 15 degrees Celsius and freezers store samples at a temperature between -25 and 15 degrees Celsius.
Some lab freezers are used to store biological samples (vaccines, for example, that have to be kept at a significantly lower temperature). In some labs are used cryogenic freezing that requires specialized equipment that is capable of generating and tolerating extremely low temperatures.
Ultra low-temperature freezers usually store samples at a temperature of -50 degrees Celsius, but sometimes it goes even bellow. They use dual compressor cascade type of system to reach these low temperatures where the first compressor is used to get a temperature of around -40 degrees Celsius. The second compressor is there to get the lower temperature that is needed. This type of lab freezers usually make more noise than a -20 degrees Celsius freezers, use more energy and produce more heat output into the room. The ultra cold freezers repair is more expensive than for a standard lab freezer or refrigerator. If there is a need for the compressor to be replaced, it is necessary to hire a professional.
