Labotemp Laboratory Digestion Unit LMD-301 provides controlled high-temperature sample digestion for multi-sample laboratory preparation, with 20 sample holes, a 450°C designed temperature, ±1°C temperature control accuracy, approximately 6–15°C/min heating rate, and 4 kW heating power. Its 5.5-inch color touchscreen, 9 programmable recipe groups, and 1–999 minute timer support repeatable digestion workflows. The system supports analytical procedures in which samples are heated with strong acids and catalysts to break down organic matter and convert organically bound nitrogen into ammonium ions (NH₄⁺) in the digestion medium; this ammonium is later released as ammonia during a subsequent distillation step for quantification. This digestion approach is part of a standard laboratory method used to determine total nitrogen content in organic and inorganic samples. Over-temperature protection helps provide safer operation during prolonged heating.
The LMD-301 can be paired with a Waste Gas Collection Hood to manage acid mist and fumes generated during digestion. The hood provides 20 collection ports and 2 extraction openings, while PTFE sealing caps offer high-temperature and acid resistance. Its welded stainless-steel construction provides corrosion resistance when handling acidic digestion fumes, with collected gases directed toward a suitable neutralization or exhaust system. This combination provides a practical setup for laboratories performing nitrogen determination, environmental testing, food and agricultural analysis, pharmaceutical research, and other acid digestion-based sample preparation procedures.
