Within a laboratory, there are many instruments that are essential for research, testing and fieldwork, ideal for the conservation of study samples, which must have the ability to keep very important substances and fluids in perfect refrigeration. In many cases, for human health.
These must have several separations or compartments and each of them has the option to control the temperature according to the user’s need. There are different types of refrigerators, which will depend on the temperature, therefore, you must know, which is the right one for what you want to conserve, is done efficiently.
Types of Laboratory Refrigerators
For the conservation of chemical and biological substances, it is necessary that the cooling capacity, achieve that the study samples continue with their activity, without reaching decomposition. In this way, it allows such important substances, such as blood and its derivatives, to be kept in good condition. That’s why this instrument is needed inside the lab.
It can be noted, that the user must have the knowledge to operate these equipment, as well as its use depending on its types, which are:
- Storage coolers: They are capable of operating between 0°C to 8°C.
- Low temperature refrigerators: They have the ability to refrigerate at temperatures ranging from 0°C to -30°C.
- Ultra-low temperature refrigerator: This refrigerator is able to store substances with temperatures relative to 0°C up to -86°C.
With each of these refrigerators, it is achieved that the substances or samples are preserved and maintained over time, in order that, at the time of performing the corresponding analyzes, they are in the best conditions and the results obtained can be completely reliable.
Laboratory Refrigerator Characteristics and Maintenance
The laboratory refrigerators are composed of an evaporator, storage cabinet and thermostat, where it must be placed and ensure that each substance or sample allows to control the temperature and cooling system.
Also, the system that complies with the evaporator, is located at the top of the refrigerator cabinet, which determines the temperature below 0°C, capable of reaching temperatures from 5°C to 30°C. Generally, the laboratory refrigerator has a similar appearance to a domestic refrigerator, therefore, it will not be so complex to identify it and know what its function is.
In another sense, refrigerators are equipment that is generally not very demanding from the maintenance perspective, although they are demanding in relation to the quality of power systems.
Therefore, the most common maintenance routines are described below:
- Ensure that the interior shelves of the refrigerator are clean. They are usually made of metal mesh, to which a coating is applied to prevent corrosion.
- Wipe with a soft detergent with a damp cloth, gently rub, the upper and lower surfaces. Dry and relocate to original position.
- Remove dirt and dust from the condenser surface. Use a vacuum cleaner equipped with a suction brush to sweep the entire surface of the condenser, removing dirt or dust from the condenser.
