Generally, the laboratory refrigerator, is made of resistant steel material and consists of an evaporator, storage cabinet located under the evaporator, where you can place shelves for storage, as well as the thermostat, which allows you to open and close an electrical circuit by action of a change of temperature, and the cooling system. The evaporator, located on top of the cold cabinet with sub-zero cooling functions, can reach temperatures of 5 to 30 °C.

It complies with the processes of conservation of samples and own substances for future studies, such as blood and derivatives, biological fluids and reactive tissues, chemical, biological and strains.

A refrigerator is equipment specially designed for use in the laboratory, the main purpose of which is to keep very important substances, fluids and samples in perfect refrigeration. It is a device that provides a controlled environment, where these substances are conserved to optimal conditions.

This equipment is used to cool samples or specimens for preservation. They consist of refrigeration units for storing blood plasma and other blood products, as well as vaccines and other medical or pharmaceutical supplies. They differ from traditional refrigerators used in homes or retail establishments because they need to be completely hygienic and completely reliable.

Laboratory refrigerators are equipment designed to store samples of patients' blood and blood products, urine, and cerebrospinal fluid after the test, and to store samples obtained microbiologically. The cooling range of these common laboratory refrigerators is normally 1C-8C, depending on the laboratory protocol. These kits are reliable and also store reagents in a very stable way, as they commonly have a circular paper temperature control system, so that any deviation is easily detected.

Laboratory refrigerators may include anti-freeze fans to keep moisture in the cooling chamber. This allows a drier climate for dry reagents, or materials that are susceptible to moisture contamination. Among its applications is the use of these equipment to store microbiological materials such as media plates, making procurement easier, and inventory of supplies can be done without opening doors when they are glass. These glass doors are double to triple glazed and have a sandwich vacuum for excellent insulation. Air is often circulated as a fan to control moisture and cooling.
