Smart Microwave Digestion System

  • Product Number:LD-WB6
  • Product Difference:High-pressure digestion vessels process ≥6 samples per batch, accelerating sample digestion reactions under high-pressure conditions

Product Introduction

The intelligent microwave digestion system provides a rapid, safe, and automated solution for accelerating sample digestion reactions under high-pressure conditions. It is widely used in food science, environmental protection, disease control, quality supervision, commodity inspection, research institutes, and other fields.

Product Features

  • Features continuous automatic frequency conversion control without microwave pulses, extending instrument lifespan and ensuring uniform electromagnetic wave distribution.

  • 360° continuous rotation in the same direction guarantees uniform microwave distribution, ensuring identical microwave environments for all samples and enhancing experimental consistency.

  • The 52L large-capacity chamber is constructed from 316L stainless steel. Its self-locking, buffer-equipped explosion-proof door ensures operator safety and structural integrity during abnormal reactions. The door-chamber seal meets national standards for microwave containment.

  • The safety explosion-proof membrane provides dual protection. When pressure inside the vessel exceeds the membrane's tolerance, it ruptures first to vent gases, preventing vessel damage and personal injury.

  • A dual temperature-pressure control system regulates digestion parameters with real-time display.

  • Microwave heating automatically stops when the pressure inside the vessel exceeds the preset safety threshold.
