The equipment has high-throughput sample processing capability, combined with 360 ° continuous rotation technology in the same direction, ensuring the uniformity and repeatability of sample processing within the batch. The control system adopts non-contact infrared precise temperature control, and can intuitively monitor the entire temperature curve through a large-sized touch screen, with intelligent and easy operation.

The whole machine adopts a corrosion-resistant chamber and high-quality PEEK/PTFE digestion tank components, with a sturdy and durable structure. This instrument is an ideal choice for efficient and safe sample digestion in industries such as food, environment, geology, metallurgy, etc. due to its reliable core performance, comprehensive safety guarantee, efficient batch processing capability, and friendly intelligent operation.

2、 Instrument principle

microwave digestion systemWorking based on the principle of combining microwave heating with high-pressure chemical reactions. The microwave emitted by the core magnetron is absorbed by polar molecules (such as water and acid) inside the digestion tank, causing high-speed oscillation and friction of the molecules, achieving rapid and uniform heating from the inside of the sample, greatly reducing the pre-treatment time.

To ensure precise and controllable process, the instrument adopts non-contact infrared temperature sensing technology to monitor the temperature changes of each reaction tank throughout the process. The unique 360 ° continuous rotation design ensures uniform heating of all samples and good consistency of results. The system has multiple built-in safety mechanisms. Once abnormal temperature or pressure is detected, the microwave emission will be automatically stopped and pressure relief protection will be activated, achieving the unity of efficiency and safety.
