How to deal with overheating of microwave digester

Microwave digester adopts unique and fashionable touch sensitive intelligent panel, intelligent sensing button, non-contact touch technology, high sensitivity, quick response, safe and reliable against acid gas corrosion The digestion rotor rotates continuously in one direction in the furnace cavity, avoiding the uneven heating of micro slope caused by the rotor stop collar, reducing the impact on the motor and prolonging the service life Microwave digesters have been developed for more than 20 years, and about 20000 domestic microwave digesters are distributed in the north and south of China Microwave digester has developed rapidly from a single modified household microwave oven device to an advanced laboratory dedicated microwave digestion workstation / system At present, there are many kinds of domestic microwave digesters with different performance and application Main functions and application fields: microwave digestion of samples in high-temperature, closed containers for acid digestion, not only greatly reduces the sample processing time, but also realizes the advantages of traditional sample processing methods, such as Zui less acid consumption, Zui low background value and complete recovery rate The microwave digester may overheat (i.e higher than the boiling point temperature) When the electric furnace is heated, the heat is transmitted to the sample from the outside to the inside through the wall, and bubbles are easily formed on the surface of the wall, so it is not easy to overheat The temperature is kept at the boiling point, because the gasification needs to absorb a lot of heat In the microwave field, the way of "heating" is totally different, and the energy is directly transformed in the system Due to the lack of "core" of forming gas "bubble" in the system, it is easy to overheat some reagents with low boiling point in the closed container It can be seen that the reagents in the closed sample dissolving tank can provide higher temperature, which is conducive to sample digestion The technical index of the microwave digester is the design of the top explosion-proof furnace chamber door, which can protect the operator from microwave radiation and improve the service life and safety of the furnace chamber to a large extent The unique "on-off" type quantitative pressure relief function of digestion tank ensures the safety of digestion process and eliminates the need for conventional consumables such as explosion-proof membrane Full touch screen operation, real-time display of temperature and pressure change curve, keep abreast of the reaction
