Microwave digestion instrument

Product Description:

The YT-WB20 high-throughput intelligent microwave digestion instrument provides a fast, safe, and automated solution for samples, accelerating the speed of sample digestion reaction under high pressure conditions. It is widely used in fields such as food, environmental protection, disease control, quality supervision, commodity inspection, and scientific research institutions.

Product features:

The instrument adopts microwave non pulse continuous automatic frequency conversion control, which extends the service life of the instrument and the uniformity of electromagnetic waves. The chamber is made of 52L large volume 316L stainless steel chamber material, with a self-locking buffer explosion-proof furnace door. When the reaction is abnormal, the buffer structure ensures the personal safety of operators and the furnace door structure is intact and undamaged. The furnace door and chamber are tightly combined, and microwave leakage meets national standards. The instrument adopts a temperature and pressure dual control system to control the pressure and temperature of the digestion experiment, with real-time display. 360 ° continuous rotation in the same direction, uniform microwave, ensuring the same microwave environment for each sample, and improving the consistency of experimental results. When the pressure inside the tank exceeds the set protection value, the microwave will automatically stop heating. The safety explosion-proof film has a dual safety function. When the pressure inside the tank exceeds the pressure that the explosion-proof film can withstand, the explosion-proof film will rupture first, causing gas to escape, preventing damage to the tank and harm to the human body.
