What is a microplate reader?
A microplate reader is a specialized spectrophotometer designed to read the results of a technique used to determine the presence of specific antibodies or antigens in a sample. The technique is based on the detection of an immobilized antigen on a solid phase, by means of antibodies that, directly or indirectly, produce a reaction whose product can be read by the spectrophotometer.
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.
The Microscope and its evolution
The first great advances in science and in particular in the biological sciences are due in part to the invention of the optical microscope, when at the end of the seventeenth century Anton van Leeuwenhoek, carving lenses, was able to appreciate the world that due to its small size was impossible see with the naked eye: the microscopic world.
What is a centrifuge?
Centrifugation is a mechanism for separating mixtures (in particular, those made up of solids and liquids of different densities) through their exposure to a rotating force of a certain intensity.
