How does a natural convection oven work?
A natural convection laboratory oven is one that extracts the air from the environment in which the oven is located. So it transmits heat in a uniform way throughout the equipment creating a natural air circulation.
What is electrophoresis?
Electrophoresis is an analytical method in which a controlled electric current is used in order to separate biomolecules according to their size to electric charge ratio, using a gelatinous matrix as a base. This technique has a variety of practical uses, such as forensic medicine for human identification, the human genome project, protein and genetic mutation research, and clinical diagnostic testing.
What are the uses of a spectrophotometer?
Spectrophotometry quantifies the concentration of a specific substance that is present in a sample by comparing the amount of light that enters a sample compared to the amount of light that leaves the sample at a specific wavelength. It can be used theoretically to measure any substance that absorbs light.
Safety levels in a biological safety cabinet
The biological safety cabinet represents a primary containment barrier that allows safe work with biological agents. It is a device designed to prevent the escape of bioaerosols from the work area and, therefore, protects people and the environment from possible exposure to biological agents. There are three types, known as: class I, class II and class III. Laminar flow cabinet designed exclusively to protect the product are not considered CSB.
When to calibrate my spectrophotometer?
The spectrophotometer is a piece of equipment used in the laboratory in order to determine the concentration of a substance in a solution, thus allowing quantitative analysis to be carried out. Proper calibration of the spectrophotometer is a fundamental factor in obtaining an accurate and reliable measurement.
What is a hematology analyzer?
Hematology analyzers are equipment used to perform complete blood counts, or hemograms. They carry out quantitative and qualitative analyzes of blood elements: red blood cells, white blood cells, and platelets. They are mainly used in medical biology analysis laboratories or in hospitals with hematology services.
What is a humidity incubator?
A humidity incubator is a laboratory equipment that, in addition to controlling the temperature of the indoor environment, also controls the humidity, through a refrigeration system, instead of direct heating. They allow the development of an infinity of experimental work, since with it microbiological and cell cultures can be maintained thanks to its ability to achieve the optimum temperature and humidity for this, as well as the levels of carbon dioxide and oxygen.
How to use an analytical balance correctly?
The balance is a piece of equipment that measures the mass of a specific body, providing accurate data about its weight. Among the many existing models, the analytical balance that has a high power of rigor stands out, since with it great precision can be obtained.
What is pathological anatomy?
Pathological anatomy is the science that studies the pathophysiological and morphological alterations of the disease. It studies the disease at an organic, tissue, cellular, subcellular, and molecular level.
Types of balances in the laboratory
The most common types of laboratory balances and scales are ultramicrobalances, microbalances, semi-microbalances, analytical balances, and precision balances.
