They are equipment that has a digestion system, which is used to mineralize solid samples from which we want to obtain reliable information at elemental level, a spectroscopic technique is used, and requires that the sample to be examined is in liquid state, so if the requirements of the analyzes require preparing the sample for analysis of food, textiles, plastics, wastewater treatments, cosmetics and other applications, you need a microwave digester, and certainly the best and most reliable are the YR KALSTEIN series.
Microwave digestion equipment is capable of performing the complete process in multiple samples simultaneously in a reduced, fast and effective time, its usefulness goes beyond, also digest samples of varied nature and with different acid mixtures in the same cycle, to perform this procedure are required reagents, such as nitric acid, hydrochloric acid and hydrogen peroxide, the choice of one of them will depend on the sample with which you will work.
How does a Microwave Digester work?
Since the microwave digester is a procedure for the preparation of the samples, it works as follows: the sample is heated in transparent, closed vessels next to the acids required for the test, under a temperature for this process between 220-240ºC depending on the sample. These equipment generate electromagnetic radiation at a frequency of 2450 MHz. The molecular movement of the radiated material causes it to heat up. Radiation penetrates into glass, ceramic and plastic materials, while metals reflect this wavelength.
Microwaves are equipped with a unique reaction chamber, where you have total control of the conditions in which digestion is being generated, allowing all samples to be in a common space; In addition the amount of sample and acid required are smaller, saving time and resources to the laboratory, working with smaller volumes.
Microwave applications in the laboratory
- In medicine: heating contrast media and blood plasma.
- In biology: enzyme assays, tissue fixation, sample preparation, careful heating of agar in bottles, drying.
- In chemistry: food analysis, synthesis, preparation and heating of samples, concentration and evaporation of solutions, drying substances.
- In the industries: agriculture, environment, plastics, petrochemical, geochemical, metals and ceramics among others.
KALSTEIN Models of Microwave Digesters
Here are the best existing equipment on the market, the KALSTEIN microwave digesters, YR series, we tell you some of the most relevant features, however, if you want to know them in more detail, enter HERE
- Microwave Digestion System YR04959 // YR04960: Temperature and pressure monitoring system without contact. The advanced non-contact IR sensor could measure the real-time temperature of sample solutions in each digestion vessel. Each value of real-time temperature and pressure is displayed throughout the digestion process, allowing clear verification of digestion conditions.
- Microwave digestion system YR04957 // YR04958: Special design sample digestion container. Automatic ventilation and self-closing structure that ensures digestion vessels can automatically release pressure and instantly reclose when a sudden squeeze situation occurs.
- Microwave Digestion System YR04953 // YR04956: It is a new microwave digestion system designed, has a new design and is completely updated with higher performance and a safer protection system. Smart design and perfect performance make it very well received by users worldwide.
