Spectrophotometers, what are they and what are they used for?
It is an instrument widely used in laboratories, it is responsible for measuring the intensity of the light that is absorbed when passing through a solution, that is, the beam of light of electromagnetic radiation or light, and then perform an analysis where it can be identified, qualifiers and quantifiers as is its energy. As well as, allow to identify its efficiency, sensitivity, resolution and spectral range.
Flake ice machine
Flake ice cools faster than any other type of ice, it is a dry and sub cooled ice, small, available in different forms, which has more capacity to cool the products and keep them for longer periods of time, if it is compared with ice cubes. It is for this reason that flake ice makers have been developed to increase the efficiency in the production of ice, and in this way make this resource available quickly and in large quantities. Since ice is used for steps that require ice baths in the various procedures carried out in different laboratories.
Electrophoresis chamber
The electrophoresis chamber is the device where the sample is introduced for said process; and where the electromagnetic field that is formed in the electrophoresis process is created, said field takes place within a buffer solution in which the gel is submerged; the high concentration of electrolytes makes the transition of electric current possible.
How does a spectrophotometer work?
The spectrophotometer is a piece of equipment frequently used in laboratories. It is a device that measures the intensity of the light absorbed when passing through a solution, it is used to determine which is the beam of electromagnetic radiation or light, and thus identify, qualify and quantify how its energy is; in addition to allowing to identify its efficiency, sensitivity, resolution and spectral range. So, basically it serves to know what the concentration of the substance in a solution is and thus it can be analyzed under the quantitative approach.
Types of microscopes for laboratory and field
The microscope is an instrument that allows observing elements or structures that can not be observed at the naked eye, through lenses, viewers and light rays, which bring or enlarge the image on scales suitable for examination and subsequent analysis. He was invented by the Dutch Zaccharias Janssen in the sixteenth century.
What does a pathologist do? What is a pathology laboratory?
A pathologist is a doctor who specializes in pathological anatomy, a science that studies the pathophysiological and morphological alterations of the disease, that is, it studies the disease from its organic, tissue, cellular, subcellular, and molecular level. This professional is a highly qualified person, with solid theoretical and practical knowledge, which allows him to handle procedures in the investigation of diseases and possible diagnoses.
Microscopes – types of condensers
The microscope is an instrument that increases the size of an image and allows you to see more details than would be possible to perceive with the naked eye. The condenser of a microscope is a key part of a microscope, it focuses the light that passes through the stage of the microscope where the sample is placed, thus providing illumination, contrast and clarity in a uniform way to the sample.
Electrophoresis: steps for a run of gels
Electrophoresis is a molecular biology technique where controlled electric current is used to separate biomolecules according to their size-to-electric charge ratio, using a gelatinous matrix (gel) as a base.
What is a laboratory magnetic stirrer?
A magnetic stirrer is laboratory equipment that uses a rotating magnetic field to mix one or more solutes with a solvent in an automated way. It is considered the most widely used type of stirrer, since it is silent, efficient and does not have direct contact with the sample.
Thermal Cycler Protocols (PCR)
A thermal cycler is a laboratory equipment that allows to carry out the polymerase chain reaction (PCR) efficiently and quickly, by means of the automatic and cyclical realization of the temperature changes that are required for the amplification of a chain. deoxyribonucleic acid (DNA), from a thermostable enzyme. PCR enables a small number of DNA molecules to be amplified many times, exponentially.
