What is sickle cell anemia?
Sickle cell anemia is a chronic, hereditary and familial hemolytic disease, which black subjects suffer almost exclusively. It owes its name to the fact that the erythrocytes of…
The Centrifuge: an Essential Element
A centrifuge is an apparatus that applies a sustained centrifugal force (that is, a force produced by rotation) to impel matter out of the center of rotation. This principle is used to separate particles in a liquid medium by sedimentation. In general, the centrifuge is used in laboratories as a process of separating the sedimentation of liquid and solid components.
Care and correct use of balances
The balances are instruments that are used to measure the mass of a body or also the weight of it. Its origins lie more than 3,500 years before Christ, in Egypt.
The scales differ from each other by the design, the principles used and the metrology criteria they use. At present, it could be considered that there are two large groups: mechanical scales and electronic scales.
How does a fume hood work?
A hood or hood in laboratories are an effective means of capturing flammable, irritant, corrosive, carcinogenic vapors, etc. to prevent personnel exposures and avoid their dissemination in the laboratory atmosphere. When the hatch is down, the cab is also a physical barrier that protects the operator from hazards such as splashes, aerosols, fires, and minor explosions.
What is a laboratory incubator?
The laboratory incubator is a piece of equipment used to maintain microbiological and cell cultures. How is this achieved? The incubator has the ability to maintain optimal temperature and humidity, as well as the levels of carbon dioxide and oxygen that may be present in the incubator.
What is a Spectrophotometer?
A spectrophotometer is a device that is used in laboratories to determine what the beam of electromagnetic radiation or light is and thus identify, qualify and quantify its intensity.
In the same way, it allows determining its efficiency, sensitivity, resolution and spectral range. Which will depend on the variabilities of the design and the choice of the optical components it contains.
What applications do refrigerators have in the healthcare sector?
The refrigerator is an equipment whose 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.
Two main types of refrigerators are distinguished in the health sector: laboratory refrigerators and pharmacy refrigerators. Both must allow easy and complete cleaning of surfaces and must offer high reliability, especially with regard to temperature control. Some models also offer an automatic defrost and / or forced air cooling function.
What should I do when there is a spill in my analyzer?
Semi-automated chemistry analyzers, in general, are very specialized and expensive equipment. Its conservation depends largely on the way of installation and use. This team is one of the main diagnostic and research instruments developed by humans. It is used in the laboratory in order to determine the concentration of a substance in a solution, thus allowing quantitative analysis.
How to choose the right biochemical analyzer?
A biochemical analyzer is a laboratory equipment, which has among its functions to measure the level in blood or other body fluid, of analytes such as glucose, cholesterol, triglycerides, uric acid, proteins and enzymes.
The hematological analyzer: A great medical innovation
The knowledge about the pathophysiological changes that accompany the health-disease process reached by the medical sciences during the second half of the 20th century was vertiginous. This translated for the clinical laboratory branch, in the emergence and placement in the hands of its professionals, of an increasing number of determinations aimed at complementing the physical examination and medical interrogation, to finally establish a diagnosis.
