Laboratory refrigerators and freezers, temperature ranges

A laboratory refrigerator is equipment that allows the effective storage of all types of substances that are refrigerated, whether liquid, solid or homogeneous. This is why it is considered an essential piece of equipment within the laboratory. 

What is the importance of the laboratory refrigerator?

The refrigerator in a laboratory is one of the most important equipment. Its function is to maintain, in a controlled environment (refrigerated space), various fluids and substances, so that they are kept in good condition the lower the temperature, the less chemical and biological activity. This requires that the refrigerator’s interior temperature be below room temperature.

Role of the refrigerator: COVID-19 vaccine storage

Vaccines are an important medical product that is especially sensitive to the health emergency caused by COVID-19. The right cooling makes a difference and can save lives. But why is it so important where and how vaccines are stored? In this article we will define what is the cold chain and what are the fundamental differences between a scientific refrigerator and a domestic refrigerator.

Refrigerators, freezers and vaccine storage

Safe storage of vaccines is a crucial component of protecting patients against disease. Failure to store vaccines properly may result in loss of patient confidence in the vaccine program.

Refrigerators and Freezers: Types

Refrigerators and freezers are valuable laboratory equipment when it comes to preserving and protecting scientific or medical material. Having the right refrigerator or freezer is extremely important when thinking about sample storage. If the temperature fluctuates, the risk of damaging vaccines, for example, is very high.

Elisa washing machine to detect Human Lymphotropic Virus infection

The microplate washing machine is a machine designed to clean the plates used during the Elisa practice, by processes of infusion and suction of the substances or show that they are embedded in the polyethylene support. It has tanks that contain liquids, one of them is in a washing buffer and the other one collects the substances that are discarded.

What should you consider when using a scale?

The balance is used to measure the mass of a body or substance or also the weight thereof; since there is a well-defined relationship between mass and weight. In the laboratory, the balance is used for quality control activities, for preparing mixtures of components in predefined proportions and for determining specific densities or weights. Its origins lie more than 3500 years before Christ, in Egypt.

Do you know how an analytical scale works?

  It must be taken into account that weight is the force that the gravitational field exerts on the mass of a body; such force being the product of mass by the local acceleration of gravity.  The local term is included to emphasize that acceleration depends on factors such as geographical latitude, height above sea level and density of land, where the measurement is made. This force is measured at Newton. Did you know what? The scale has other names, including scales and weights.

How to correctly use an analytical balance?

Analytical balance is a measuring instrument that offers a high degree of accuracy, but requires operator experience and skill. For its operation, it must be positioned under a specific environment and have the environmental conditions controlled so that it does not suffer alteration in the absolute value of the weighing.

Care and proper use of the scales

In the laboratory, they are used to perform quality control, prepare mixtures of components in predefined proportions and to determine specific densities or weights. Therefore, it is necessary to have optimal conditions from the environmental and structural point of view, as well as to provide the correct maintenance of these equipment, in order to ensure a correct weighing.
