PCR thermal cyclers: how it works?
PCR is a simple and widely used procedure in the expansion of DNA, which is essential in any laboratory, as it is more effective and faster,as in the diagnosis of diseases such as COVID-19, HIV or cancer, allowing early arrest to avoid the spread of infections, and also establish treatments that improve the quality of life of patients.
Laboratory Water Baths: Uses and types
Among its main uses we have the heating of reagents, fusion of substrates or incubation of cell cultures. It is also used to carry out certain chemical reactions that occur at high temperatures. The water bath provides a uniform source of heat that allows flammable chemicals to be heated instead of an open flame and thus avoid contact.
Laboratory pipettes, steps for its correct use
Pipettes are precision devices ideal for liquid measurement needs in quality control and clinical testing laboratories. They are laboratory instruments used to absorb and transfer small volumes of liquids.
Recirculating bath with cooling: types and uses
A recirculating cooling bath is a laboratory equipment used to cool samples and reagents in an efficient and reliable way through the use of constant recirculation, that is, this equipment performs refrigeration tasks in the laboratory in a safe and reproducible way.
Biological Safety Cabinets (CSB): Types and Uses
Is a machine that offers a closed and ventilated workspace, which allows to perform many procedures and scientific experiments protecting the user, the sample and the present environment; it eliminates and prevents contamination, and is indispensable in any laboratory.
Thermocycler for PCR: types and applications
The PCR machine allows to perform dna sequence studies or contagious diseases existing in the blood, currently, this device receives great demand in the arrest of the SARS-CoV-2 coronavirus virus, the advantages of this device stands out in the area of molecular biology; detecting hereditary diseases, relating kinship, among others related to DNA.
How many types of laboratory pipettes are there?
It is a container that is used in the different laboratories of chemistry and medical sciences to make measurements in volume, the important thing about this instrument is that it must be made of material that allows to visualize the liquid content, they can be made of glass or transparent plastic, this must allow to measure the aliquot of a liquid with extreme precision, It must also have certain basic characteristics such as being a transparent tube, having one of its conical tips, has a graduation with which it marks the different measures in volumes.
What does homogenized mean?
A homogenate refers to something that has been subjected to a homogenization process. Homogenization refers to the processing of a sample or solution so that it becomes uniform, it is generally used with components that are not soluble in each other, that are barely miscible or that are not miscible at all.
What are the characteristics of an ion meter?
An ion meter is an electrochemical analytical device that is used to measure ion concentration in a solution. It is used with several ion electrodes (ISE).
Spectrophotometer, types and parts
A spectrophotometer is a laboratory instrument used to measure the absorbance of a sample as a function of the wavelength of electromagnetic radiation and thus to determine the concentration of substances in a solution. In other words, it makes it possible to know the concentration of substances in a solution and thus to analyze them from a quantitative point of view.
