The instrument adopts microwave non-pulse continuous automatic frequency conversion control, which prolongs the service life of the instrument and the uniformity of electromagnetic waves.
The cavity is specially made of 66L large-volume 316L stainless steel cavity material, and the self-locking buffer explosion-proof furnace door. When the reaction is abnormal, the buffer structure ensures the personal safety of the operator and the integrity of the furnace door structure.
The furnace door and the cavity are closely combined, and the microwave leakage meets the national standard.
The instrument uses a temperature and pressure dual control system to control the pressure and temperature of the digestion experiment and display it in real time.
360 ° continuous rotation in the same direction, uniform microwave, to ensure the same microwave environment for each sample, improve the consistency of experimental results.
When the pressure in the tank exceeds the set protection value, the microwave will automatically stop heating.
The safety explosion-proof film has a double insurance function.
