PREEKEM M3 Microwave Digestion System
| Feature Category | Details |
|---|---|
| Working Principle | Uses 2450 MHz microwaves in a resonant cavity to uniformly heat sealed vessels, raising temperature and pressure to accelerate digestion. Sensors control full-vessel temperature and pressure for safety and efficient digestion. |
| Microwave Source | Dual magnetrons, 1200 W output power |
| Microwave Frequency | 2450 MHz, non-pulse continuous microwave emission |
| Cavity Material | High-strength 316L stainless steel with 5-layer PTFE spray coating |
| Cavity Design | Industry-standard resonant cavity, optimized waveguide, precisely calculated cavity volume |
| Temperature Control | Genuine full-vessel temperature control via upgraded “R-Temp” platinum thermal sensor |
| Pressure Control | Full-vessel pressure monitoring with safety dual monitor system |
| Cooling System | Twin ultra-fast air cooling with optimized duct design and intelligent auto air volume control |
| Safety Features | Individual float safety door for surge pressure release and self-checking system |
| Sample Capacity | Rotor holds up to 16 vessels (various volumes) |
| Temperature Range | 0 – 300 °C |
| Pressure Range | Up to 100 bar (via pressure sensors) |
| Applications | Acid digestion, solvent extraction, sample preparation for food, soil, pharmaceuticals, and environmental samples |
