Refrigerators and Freezers

A laboratory refrigerator is a piece of equipment that allows to efficiently conserve all kinds of substances that are cooled in it, whether they are liquid, solid or homogeneous substances. Reason why it is considered essential equipment within the laboratory. It acts by lowering the temperature, thus allowing control of the effect it has on the substances whose composition and structure are to be preserved, this is because the lower the temperature, the lower the rate at which chemical reactions occur and metabolic, which deteriorate the compounds. That is why they are used in the conservation of blood and derivatives, biological fluids and tissues, reagents, chemicals, and bacterial strains.

Types of Refrigerators and Freezers a Laboratory may require

Ultra Freezer

Refrigerators and freezers are essential equipment in every laboratory, since these equipment guarantee the preservation of substances by generating and maintaining negative temperatures up to thermal levels. For optimal operation, they must meet certain characteristics, such as optimized thermal insulation, temperature maintenance and the ability to program and regulate the temperature with the support of electronic alarms that notify the laboratory staff of breakdowns or malfunctions. For optimal operation, the refrigerator must be located in a cool and ventilated environment with at least one window, to avoid the concentration of hot air. In addition, it must be placed 15 cm away from the wall, which will promote air circulation. The sun’s rays should not hit the refrigerator directly, since ultraviolet rays could inactivate the vaccines. It is also recommended to place it on a wooden base to avoid electricity leakage.

Upright Freezer

A laboratory freezer is a freezer used to store samples for scientific or medical purposes. These freezers are designed to maintain a constant temperature and prevent samples from thawing or freezing. They come in a variety of sizes and shapes to meet the needs of different laboratories.

Upright freezers are common in laboratories because they take up less space and are easier to access than horizontal freezers. Some are equipped with features such as alarms and automatic shutoffs to prevent samples from thawing or freezing.

Refrigerators and Freezers in Operation

The process of storing hematological plasmas with the use of laboratory freezers is very effective in preserving the quality and quantity of the cellular components of blood plasma. Frozen blood plasma can be stored for several years. However, it is important to note that frozen blood plasma is not stable indefinitely.

After frozen blood plasma has been stored for a period of time, it should be thawed and used immediately. If blood plasma is thawed and stored again, it degrades rapidly. Therefore, it is important to note that frozen blood plasma can only be stored for a limited period of time.
