The refrigerator in the labs is one of the most important equipment. Its function is to keep different fluids and substances in a controlled temperature environment, so that they are kept in good conditions, like Kalstein. The lower the temperature, the less chemical and biological activity we will find in the different fluids.
To achieve this, it is required that the internal temperature of the refrigerator be lower than the ambient temperature. The laboratory uses various types of refrigerators that could be grouped into the following ranges:
Conservation coolers operate in the range from 0°C to 8°C.
Low temperature coolers operate in the range from 0°C to -30°C
Ultra-low temperature coolers operate in the range from 0°C to -86°C
There are even some much colder ones, so you can get a whole range of refrigerators depending on the activities that the laboratory performs, you should select the refrigerator that is appropriate to its functions, if you are close to having your own laboratory you can go thinking about what you really need.
For example: If you need to keep whole blood, simply use a refrigerator known as the Blood Bank refrigerator, which provides temperatures between 0°C and 8°C. On the other hand, if a particular strain needs to be conserved, an ultra-low temperature cooler is required.
