Laboratory Sample Homogenizers
A homogenizer is a very important piece of equipment among the components of a laboratory, because it allows to carry out the homogenization process of different types of materials; such as tissues, food, plants and other biological or chemical elements.
How does a homogenizer work?
The homogenizer is laboratory equipment that is used for the homogenization of a variety of materials, such as tissues, plants, food, soil, and many others.
What is the importance of homogenizers in the laboratory?
In most laboratories, one of the initial steps in the process of analyzing a sample is the homogenization of the same. In some cases, the material that is received in the laboratory can be immediately sent for culture or any other analysis. In other circumstances, the material has different characteristics that can interfere with the analysis and promote the obtaining of erroneous results. These qualities of the sample are due to its physical or chemical properties, such as hardness, sugar content, fat or moisture.
What are the procedures of Microwave Digestion in environmental samples for the agricultural sector?
Microwave digestion is a technique used to convert specific solid samples into suitable solutions for further analysis in spectrophotometry or polarography. It is based on the chemical digestion of the solid sample by using a liquid reagent, which is usually a mineral acid, then the sample together with the acid are capped in a closed container. When heating the closed container, the temperature increases rapidly, well above the boiling point of the acids, this allows the digestion process to accelerate and finish very quickly, in fact, a typical digestion lasts between 20 and 40 minutes, making this technique a very powerful tool.
Microwave digester: in which scientific sectors is it used?
The use of this equipment for different scientific processes is proven thanks to the scientific researchers in the areas of chemistry and engineering, where the use of microwaves for NTK analysis and oxygen demand is validated, due to the effective system of temperature that these processes require, thanks to the microwave digester samples and tests reach a necessary temperature in a shorter time and without thermal degradation.
Microwave Digestion System in Tumor Samples to Detect Cancer
Microwave digestion is a technique used to break down the materials in a test sample. By adding strong acids and even bases and heating, the sample homogenization process is accelerated. This results in a solution in which there are highly solubilized organic materials and metal ions, suitable to perform a spectrophotometry analysis and know the components that make up the resulting solution.
How to ensure food quality with Microwave Digester
Microwave digesters are equipment that perform sample digestion in order to obtain information about its components at the elementary level, they are used in many fields, from biology, chemistry, medicine, textile industry to the cosmetics industry. Microwave digestion is used hand in hand with the spectrophotometry technique, since in the latter it is necessary that the sample is in liquid state to be able to analyze it.
What is a microwave digester used for?
The applications of this equipment are wide in different areas, generally used to mineralize solid samples from which information is obtained at elemental level through spectroscopic technique, so it is necessary that the sample is in liquid state, this apparatus is present in laboratories dedicated to the Environment, agriculture, food, plastics, petrochemical industry, geochemical industry, metals, ceramics.
Microwave Digester: how does it work?
This equipment guarantees the preparation of samples for elemental analysis in analytical chemistry, performs a procedure where electromagnetic radiation is produced at a frequency of 2450 MHz; this makes it warm, where radiation penetrates glass, ceramic and plastic materials, while metals reflect this wavelength.
How is a Sample Digested?
The digestion of samples is carried out through standard procedures for the preparation, by heating them, in transparent airtight containers, together with the acids necessary for the studies. For this, the Microwave Digestion equipment is used, where it applies usual parameters, such as temperature, which range between 220-240ºC, depending on the sample that requires to be subjected to heat, generating partial or complete degradation of the sample.
