Advantages of Color Evaluation Box for sample processing in the Laboratory

Color evaluation boxes are test instruments used to check the consistency of colors, subjecting the sample or product to different lighting conditions. This equipment is mainly used to eliminate the effect of metamerism, that is, the color change that occurs in an object when it is passed by different light sources. The color evaluation box comes equipped with different lamps, to ensure that this effect does not occur and thus ensure better color consistency.

Quantitative data from a Colorimeter reading

The Colorimeter is an optical device that can be used to measure the absorption of a chemical at a specific wavelength of light. This wavelength can be adjusted by using a filter and can be measured with a photometer. The colorimeter is often used to analyze the chlorophyll content of plants.

Use of the Colorimeter in scientific research

The colorimeter is a highly sensitive measurement tool used in scientific research to determine the content of a substance in a sample. It is an instrument that measures the intensity of a color and is based on the principle of selective absorption: a substance that absorbs a specific wavelength of light will appear darker than other substances that do not absorb it. The colorimeter is used to quantify concentrations of substances in solutions, and has also been used in the research of color mixtures to establish the degree of mixing.

What are the characteristics of a laboratory refrigerator?

A laboratory refrigerator is equipment designed to maintain a controlled environment (refrigerated space), where fluids, substances, and reagents used in the laboratory can be stored and stored under appropriate conditions, because the lower the temperature, the less chemical and biological activity, and the less likely it is to deteriorate or decompose.

How is a Laboratory Refrigerator made?

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.

Why are freezers and refrigerators needed in a lab?

A laboratory is a place or center provided with equipment and facilities necessary for conducting experiments, clinical and scientific research. Within the essential equipment of a laboratory we find freezers and refrigerators, these equipment keeps in a controlled environment any element, whether reagent, drugs, samples, or vaccines, so that it is kept in perfect conditions of use. The lower and more stable the temperature, the lower the chemical and biological activity.

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.
