Importance and uses of the laboratory refrigerator

Within a laboratory we find many instruments that are essential for research, testing and field work. But there is an instrument that cannot and should not be missing in a laboratory. This is the laboratory refrigerator . The substances and the samples that are handled must be conserved, for that reason is that a refrigerator cannot be missing.

What are the functions of a laboratory refrigerator?

Among the essential elements of the laboratory is the refrigerator. And it is not just any type of refrigerator, but one specially designed for use in the laboratory. It must have the ability to keep very important substances, fluids and samples in a perfect state of refrigeration. In many cases for human health.

It has several partitions or compartments and each of them has the option of raising or lowering the temperature, as needed. This will not affect the attached compartments. It even has an unusual option, if we compare it with common refrigerators, and that is to set the temperature in such a way that the refrigerator can be used at room temperature or even a few degrees lower.

Chemical and biological substances must be cooled so that the activity is lower, or even almost zero if necessary. The cooling capacity of the refrigerator ensures that biological substances, in addition to not continuing their activity, do not decompose.

Refrigeration allows such important substances, such as blood and its derivatives, to be kept in good condition, because it may be necessary to use it later, for the determination of a diagnosis.

How is the laboratory refrigerator used?

Without the laboratory refrigerator, almost all studies and tests that are done in a laboratory would not give correct results. These have the function of effectively preserving all kinds of substances that are refrigerated in it. It does not matter if the substances are liquid, solid or homogeneous. It is for that reason that this is an instrument that should be taken as a basic necessity within the laboratory. In addition, the laboratory technician or student must know well at what temperature he needs to store the substance (s). Those with which you are working or experimenting. And therefore you must know the operation of the laboratory refrigerator, to be able to make a good use of it.

Laboratory Refrigerator Main Features

Everyone who works in a laboratory should be well acquainted with the laboratory refrigerator. You must know well its parts, its components and its operation.

Laboratory Refrigerator Parts

Conservation cabinet : In this cabinet you place the substances or samples.

Evaporator: The heat exchanger device is called an evaporator where the transfer of thermal energy occurs from a medium to be cooled to the refrigerant fluid that circulates inside the device.

Thermostat: Allows you to control the cooling system and the refrigerator temperature.

Conservation Cabinet

In almost all models of laboratory refrigerators, the storage cabinet is located below the evaporator. It is in this cabinet that you can store substances and samples at “special” temperatures. Or different from the general temperature of the refrigerator, and in turn this cabinet allows you to place shelves to store said substances or samples.


The evaporator is found in the upper part of the refrigerator cabinet (in some models it may vary). To be able to determine if the refrigerator is in use, the evaporator must be at a temperature below 0 ° C, although it can reach temperatures of 5 ° C up to 30 ° C. There is no need to worry.

Appearance of the laboratory refrigerator

They usually have an appearance similar or similar to that of a refrigerator for domestic use. For that reason it is not a complex refrigerator.

Types of Laboratory Refrigerators

There are several types of laboratory refrigerators and these are classified according to their temperature.

Conservation refrigerator

This type of refrigerator has the capacity to operate from 0 ° C to 8 ° C in temperature.

Low temperature refrigerator

This type of refrigerator has the ability to refrigerate at temperatures ranging from 0 ° C to -30 ° C.

Ultra low temperature refrigerator

This type of refrigerator preserves substances at temperatures ranging from 0 ° C to -86 ° C.

Why is the laboratory refrigerator so important?

As we can see, there are several models of laboratory refrigerators and each of them are of utmost importance within the laboratory. Thanks to these efficient refrigerators, substances that have reactive origins and substances of biological origin can be preserved in the correct way. As these substances are well conserved, the analyzes that need to be done will yield optimal results.

This type of refrigerator like any other should be in a ventilated area. It should not be “glued” to the wall and if possible it should be near a window. It is extremely important that the walls of the refrigerator do not get hot and for this there must be ventilation in the room.

If the refrigerator is not in a suitable environment for its operation, it could happen that the substances stored in it could decompose or be altered. Therefore, an investigation, study or field work would be ruined.

Compressor cooler

It is used in places where electricity is constant.

Absorption cooler

It is used when there is no electricity.

Final conclusion

Like any other device that we find within a laboratory, we would say that the refrigerator is important. Although perhaps it is one of the most important. No laboratory can do without a laboratory refrigerator . It is essential to refrigerate substances. But it is also important to know its operation and installation. It should be separated at a distance of about 15 centimeters from the wall. You cannot be in a hot room, you should not give the refrigerator full sun. Care must be taken at all times that it is at the right temperature and that the walls of the appliance do not heat up. The good functioning of the refrigerator is proportional to the excellent results within the laboratory.

I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
