XT-9912 closed intelligent microwave digestion / extraction instrument
Since the development of closed microwave-assisted digestion and extraction technology and related instruments, people have increasingly demanded for the safety and efficiency of sample processing. The existing single-tank high-pressure microwave digestion instruments have gradually been replaced by multi-tank instruments. However, since the composition of the sample processed in each digestion tank is different when multiple tanks are digested at the same time, the chemical reaction speed and the pressure on each sample will be greatly different; therefore, the existing single-point pressure measurement and measurement Microwave digestion device with temperature device (that is, the pressure of one of the digestion tanks represents the pressure and temperature of all other digestion tanks in the microwave cavity). When performing multi-tank digestion at the same time, not only the digestion steps are cumbersome, but the quality and safety of digestion are both There is no guarantee of reliability.
In order to further adapt to and meet the needs of users and the market, according to user suggestions and our long-term practice and summary, the company retains the excellent characteristics of the original XT-9912 intelligent microwave digestion / extraction system, in the appearance of the instrument, interface settings, and materials of the digestion tank, etc. Improvements and upgrades have been made, and the "XT-9912" closed intelligent microwave digestion / extraction instrument has been introduced to further improve the stability and safety of the product.
