A laboratory refrigerator is very important specialized equipment. Whose function is to maintain a controlled environment (refrigerated space), where the fluids, substances, and reagents used in the laboratory can be kept in optimal conditions, since the lower the temperature, the lower the chemical and biological activity, and To achieve this it is necessary that the interior temperature of the refrigerator is lower than the ambient temperature.

How is the laboratory refrigerator used?

Thanks to the use of the laboratory refrigerator, the studies and tests that are carried out in these places give correct results. Since these equipments have the function of conserving in an efficient way, all the substances that are refrigerated in it, whether they are solid, liquid or homogeneous substances. Reason that constitutes the refrigerators in equipment of first necessity in a laboratory.

That is why laboratory personnel must know well at what temperature they need to store each of the substances that are used daily. And therefore you must know the operation of the laboratory refrigerator, to be able to make good use of it.

Laboratory Refrigerator Key Features

It is of utmost importance that laboratory personnel are well acquainted with the laboratory refrigerator. You must know well its parts, its components and its operation. Among the main parts of the laboratory refrigerator, we find:

• Conservation cabinet: Substances or samples are placed in this cabinet. In almost all models of laboratory refrigerators, the storage cabinet is located below the evaporator. It is in this cabinet that substances and samples can be stored at “special” temperatures. Or different from the general temperature of the refrigerator, and in turn this cabinet allows placing shelves to store said substances or samples
• Evaporator: It is the heat exchanger device where the transfer of thermal energy occurs from a medium to be cooled to the refrigerant fluid that circulates inside the device. 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.
• Thermostat: It is the one that allows you to control the cooling system and the temperature of the refrigerator.

Types of laboratory refrigerators

Various types of refrigerators are used in the laboratory that could be grouped into the following temperature ranges and uses:

• Conservation refrigerators: These are those that operate in the range of 0 ° C to 8 ° C.
• Low temperature refrigerators: They are those that operate in the range of 0 ° C to -30 ° C.
• Ultra Low Temperature Refrigerators: These refrigerators operate in the range of 0 ° C to -86 ° C.

As can be seen, there are several models of laboratory refrigerators and each one of them is of utmost importance within the laboratory. Thanks to the use of these efficient refrigerators, substances such as reagents, as well as biological substances, can be adequately preserved. As these substances are well preserved, the analyzes that need to be done with them will yield the expected results.

What considerations should you keep in mind when using a laboratory refrigerator?

When using a laboratory refrigerator, you must bear in mind that this type of refrigerator, like any other, must be in a ventilated area. It should not be attached 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, optimal results would not be obtained in the investigations or chemical or biological tests that are carried out.
