The importance of the autoclave in a hospital
An autoclave is a device used to sterilize medical or laboratory material, using steam at high pressure and temperature for it. The use of an autoclave eliminates viruses, bacteria, fungi and spores.
What is a high speed centrifuge?
High-speed centrifugation is an irreplaceable tool for the isolation and characterization of multiple biological structures: from biomolecules, such as nucleic acids and proteins, to cellular organelles and viruses.
What is a variable volume micropipette?
Variable volume micropipettes are the ideal precision instrument for the liquid measurement needs of clinical testing and quality control laboratories. A micropipette is a laboratory device used to absorb and transfer small volumes of liquids.
Centrifuge: rotor types
The centrifuge is a laboratory equipment that generates rotational movements, it has the objective of separating the components that constitute a substance. Today there is a diversity of centrifuges that have different objectives, regardless of the type of research or industry. Depending on the type of centrifuge, each one will have different operation and characteristics (type of rotor and type of sample holder tube).
Main applications of a CO2 incubator
A CO2 incubator is a laboratory equipment also called a gasification incubator, where the development of cell and tissue cultures is guaranteed by creating a natural atmosphere. This culture of living organisms in vitro is one of the main applications of CO2 incubators. That is why these devices are used mainly in medical research and in the pharmaceutical industry in:
Centrifugation: RPM vs. G Force
Centrifugation is one of the most important and widely applied research techniques in biochemistry, cell and molecular biology, and medicine. Today’s research and clinical applications depend on the isolation of cells, subcellular organelles, and macromolecules, generally high throughput. A centrifuge uses centrifugal force (g-force) to isolate suspended particles from the surrounding medium either in batches or as a continuous flow.
How does immersion oil work?
Optical microscopes use two basic types of objectives: dry objectives and immersion objectives. These two types of objectives differ depending on the medium between the specimen and the objective lens. In the case of dry objectives, there is no medium between the sample and the objective other than air. Immersion objectives, on the other hand, are designed to observe the sample through a layer of immersion medium that normally consists of oil. This means that just the right amount of oil needs to be placed between the coverslip that protects the specimen and the objective lens.
Microscope: Halogen vs. LED Illumination
Often high-powered microscopes cannot provide excellent quality images due to incorrect use of light sources, which generally leads to inadequate illumination of the object. You should keep in mind that any properly illuminated specimen should be free of glare and the light should be evenly dispersed in the field of view.
How does a phase contrast microscope work?
The phase contrast microscope is a type of microscope that allows you to observe live samples without using staining techniques. This microscope is based on the existence of a phase difference between the different light waves that pass through the sample to generate the image of the observation.
pHmeter: Technology and accuracy
The measurement of pH (hydrogen potential) in the laboratory is one of the most important parameters that are performed for quality control and, according to specialists in the field, it is the second most important after temperature. The determination of the pH has a great field of application: research, industry, teaching, among others. In laboratories where it is relevant to know the potential of hydrogen, a pH measuring device will always be found as a primary instrument.
