Digester for the food industry LMD-201

for environmental analysisfor quality controllaboratory

Product Overview
Labotemp Kjeldahl Digestion Unit LMD-201 is a block digestion system for rapid, uniform sample digestion prior to Kjeldahl nitrogen and protein analysis. It processes up to 20 samples per batch using 300 mL digestion tubes, with a temperature range from RT+5°C to 450°C and ±1°C control accuracy. Infrared graphite heating and PID temperature control enable fast ramp-up and consistent thermal distribution across samples, suitable for food, feed, fertilizer, soil, water, pharmaceutical and environmental laboratories.

Key Advantages

• High throughput: simultaneous processing of 20 samples with uniform graphite heating.
• Programmable operation: stores up to 500 digestion methods; 25 preloaded programs with linear and curved ramps.
• Enhanced safety and emissions control: triple-stage filtration with condensate recovery and multiple electrical and thermal protections.

Features

• Infrared heating combined with high-purity graphite conduction for rapid, uniform heating.
• PID temperature control delivering ±1°C accuracy.
• Air-duct and advanced ceramic insulation to improve thermal efficiency and reduce external surface temperature.
• Triple-stage filtration system that reduces acid fumes and recovers condensate.
• Dedicated water-jet vacuum pump for acid vapor extraction without lubrication or additional electrical drive.
• Adjustable negative suction pressure to prevent acid overflow during digestion.
• Corrosion-resistant acid collection system and components to extend service life.
• Integrated sample cooling rack to accelerate post-digestion handling and increase throughput.
• Multi-level safety protections: over-voltage, over-current, overheating and over-temperature alarms.
• 25 preloaded programs and memory for up to 500 custom digestion methods.

Applications

• Kjeldahl digestion of samples from food, feed, fertilizer, soil, water, pharmaceutical and environmental laboratories.
• Supports nitrogen and protein determination for QC, regulatory testing, research and routine analytical workflows requiring programmable, repeatable high-temperature digestion.
