Microwave digestion apparatus

Product description:

HM-WB4 Microwave Digestor provides fast, safe and automatic solutions for samples, accelerates sample digestion reaction under high pressure, and is widely used in food, environmental protection, disease control, quality supervision, commodity inspection, scientific research institutes and other fields.

Product features:

Microwave non-pulse continuous automatic frequency conversion control is adopted for the instrument, which prolongs the service life of the instrument and the uniformity of electromagnetic wave. The cavity is made of 52L large-volume 316L stainless steel cavity material. Self-locking buffer explosion-proof furnace door is adopted. In case of abnormal reaction, the buffer structure ensures the personal safety of the operator and the completeness of the furnace door structure. The furnace door and the cavity are closely combined, and the microwave leakage complies with the national standard.). The instrument adopts temperature and pressure dual control system to control the pressure and temperature of digestion experiment and display them in real time. Continuous rotation of 360 ° in the same direction and uniform microwave can ensure the microwave environment of each sample is the same and 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 rupture disk has double safety function. When the pressure in the tank exceeds the pressure that the rupture disk can withstand, the rupture disk will rupture first and the gas will escape to prevent the tank from being damaged and damaging the human body.
