TCWJ-6Type microwave digestion instrument

1、 Instrument Introduction

TCWJ-6The 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 institutes.

2、 Functional 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 cavity adopts52L large volume316LMade of stainless steel cavity material, 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 cavity are tightly combined, and microwave leakage meets the requirements. 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.360Continuous 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 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.
