Microwave digestion instrument

Functional features:
Microwave digestion instrumentBy adopting microwave non pulse continuous automatic frequency conversion control, the service life of the instrument and the uniformity of electromagnetic waves are extended. The chamber is made of 66L large volume 316L stainless steel chamber material specially designed, and the self-locking buffer explosion-proof furnace door ensures the personal safety of the operator and the integrity of the furnace door structure when the reaction is abnormal. The furnace door and chamber are tightly combined, and microwave leakage meets the standard. The instrument adopts a temperature and pressure dual control system to control the pressure and temperature of the digestion experiment, and displays them in real time. 360 ° round-trip continuous rotation, uniform microwave, ensuring the same microwave environment for each sample and improving the accuracy of experimental results. When the pressure inside the tank exceeds the set protection value, the microwave will automatically stop heating. The safety explosion-proof membrane has a dual safety function. When the pressure inside the tank exceeds the pressure that the explosion-proof membrane can withstand, the explosion-proof membrane will rupture first, and gas will leak out, preventing damage to the tank body and harm to the human body.
