Fully Automated Protein and Nitrogen Analysis with the Automatic Kjeldahl Nitrogen Distillation and Digestion Analyzer DKDN-16
Streamline and standardize your total nitrogen and protein testing with the Automatic Kjeldahl Nitrogen Distillation and Digestion Analyzer DKDN-16—an integrated, high-throughput system engineered for food, feed, agricultural, environmental, and pharmaceutical laboratories. Compliant with AOAC, ISO 5983, EPA 351.2, and DIN 32747, the DKDN-16 automates both digestion and distillation in a single workflow, delivering accurate, reproducible results for protein content, ammonium, and total Kjeldahl nitrogen (TKN) with minimal operator intervention.
Engineered for Throughput, Safety, and Regulatory Compliance
The DKDN-16 features 16-position simultaneous digestion with programmable temperature ramps (up to 450°C) and fume extraction, followed by fully automated distillation with precise reagent dosing (NaOH, boric acid, H₃BO₃), steam generation, and titration-ready distillate collection. Its closed-system design minimizes acid fume exposure, while real-time monitoring and auto-diagnostic alerts ensure process integrity and safety.
- Integrated Digestion + Distillation – 16 samples processed in parallel; no manual transfer between steps.
- Compliant with AOAC, ISO 5983, EPA 351.2 – Validated for food, feed, soil, wastewater, and pharmaceuticals.
- Precise Reagent Dosing & Steam Control – Ensures complete liberation and capture of ammonia for high recovery (>99.5%).
- Touchscreen Interface with Method Storage – Save 100+ user-defined protocols; supports titration integration.
- Advanced Safety Features – Fume exhaust, overheat protection, leak detection, and acid-resistant components.
- Data Logging & 21 CFR Part 11 Ready – Export results with audit trail, user ID, and calibration records.
Trusted in High-Throughput and Regulated Laboratories
From quantifying protein in dairy and meat products to measuring TKN in wastewater or nitrogen in fertilizers, the DKDN-16 eliminates manual errors, reduces hazardous exposure, and accelerates turnaround time. Its automation ensures compliance with ISO 17025 and GMP requirements, making it ideal for QC labs in food safety, environmental monitoring, and agricultural research.
Whether you’re validating nutritional labeling or monitoring effluent discharge, the Automatic Kjeldahl Analyzer DKDN-16 delivers the accuracy, efficiency, and traceability your nitrogen analysis demands.
