Description

Technical Field

[0001] The utility model relates to the technical field of chemical experiments, in particular to a microwave digestion instrument for accelerating dissolution. Background Art

[0002] Microwave digestion technology uses the penetrating and reactive activation capabilities of microwaves to heat reagents and samples in sealed containers, which can increase the pressure in the sample preparation container and raise the reaction temperature, thereby greatly improving the reaction rate and shortening the sample preparation time. A microwave digestion instrument is an instrument that uses microwaves.

[0003] Among them, a microwave digestion instrument with a rapid dissolution function disclosed in application number CN202021526399.4 is also an increasingly mature technology. Through the coordinated use of an eccentric wheel, a second motor, a limit groove, a fixed seat, a ball, a support plate, a first motor, a placement groove, a threaded groove and a fastening bolt, it has the advantage of rapid dissolution, which solves the problem that the existing microwave digestion instrument does not have the function of rapid dissolution, and the sample in the sample preparation container cannot be quickly dissolved during use, thereby reducing the sample preparation effect.

[0004] A microwave digester for accelerating dissolution disclosed in CN202222327252.8 is also an increasingly mature technology. By placing the storage cup on top of the table, and then placing the table in the microwave digester, and then starting the microwave digester, the liquid in the storage cup can be processed. The liquid in the storage cup can be stirred up and down by the stirring mechanism, thereby effectively preventing the liquid in the storage cup from precipitating and accelerating the dissolution of the liquid in the storage cup.

[0005] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0006] The two microwave digestion instruments can dissolve liquid quickly, but will expand when the temperature rises. If the hot gas in the digestion tank and storage cup is not discharged in time, there is a risk of explosion. Utility Model Content
