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.
