Digester for the food industry LMD-01

for environmental analysislaboratoryfor the pharmaceutical industry

Overview
Labotemp Microwave Digestion System LMD-01 is a high-throughput laboratory microwave digester for controlled acid digestion of samples at elevated temperature and pressure. The unit accepts 16 reaction vessels and features a 66 L corrosion-resistant 316L stainless-steel cavity. Continuous frequency-conversion microwave control (0–1800 W) combined with a 360° continuous-rotation turntable ensures uniform heating and reproducible digestion results.

Design & Safety

• Self-locking explosion-proof door with multi-level interlocks and automatic fault protection
• Automatic pressure relief (operational up to 10 MPa, control up to 15 MPa) and over-pressure protection
• 66 L 316L stainless-steel cavity, efficient exhaust air cooling and PID-controlled temperature ramping
