Product overview

DW-K1160 Automatic Kjeldahl Protein/Nitrogen Analyzer is unique in its intelligence, efficiency, energy saving and data sharing, bringing more new experiences to users. The product can be widely used in the fields of food processing, feed production, tobacco, animal husbandry, soil fertility, environmental monitoring, medicine, agriculture, scientific research, teaching, quality supervision and other fields of nitrogen or protein determination.

The Drawell Kjeldahl Analyzer DW-K1160 supports research, pharmaceutical, environmental, food, industrial, and quality-control laboratories. Scientific China provides model selection, configuration review, export coordination, and formal quotations.

Key features

• Up to 24-position autosampler for high-throughput batch testing.
• Side-distillation and variable-speed titration reduce analysis time by approximately one-third.
• 10-inch HD touchscreen with Android OS for real-time process control and easy operation.
• Integrated titration module and real-time titration curves improve accuracy and method optimization.
• Real-time condensate temperature monitoring ensures complete condensation and reliable results.
• Separate cleaning and testing positions help prevent cross-contamination.
• Large-capacity reagent tank supports up to 500 analyses per filling.
• User-level management and data traceability support GMP and 21 CFR Part 11 requirements.
• Customizable reports can be exported as PDF or printed directly.
• Direct balance data transfer is available with specified balance models.
• Adjustable RGB color sensor supports AOAC, ISO, PA, and USP methods.
• The K1124 autosampler connects directly to the DW-K1160 without an additional power supply.
• Automatic models are equipped with automatic pH/potential end-point recognition, no visual observation required. Setting tips: Use 0.1mol/L hydrochloric acid as titrant, and set the end-point pH between 4.6 and 5.0. For samples high in fat and protein, extend the pre-distillation time by 30 seconds appropriately to prevent ammonia volatilization and low test results.
• ① Incomplete digestion and carbonization caking of samples; ② Insufficient addition of lye leading to incomplete release of ammonia; ③ Water leakage of condenser tube and insufficient steam pressure; ④ Leakage of burette and invalid concentration of standard acid solution; ⑤ Poor sealing of digestion tube causing ammonia leakage.

Applications

• Food and Agricultural Products Industry
• Detects protein content in grains, dairy products, meat, beverages, and soy products, as well as specific indicators such as ammonium salts in soy sauce and sulfur dioxide in daylilies; assesses the freshness of aquatic products and meat products (volatile basic nitrogen).
• Feed and Livestock Industry
• Accurately determines the crude protein content in feed ingredients and finished products to ensure compliant nutritional ratios in animal husbandry.
• Agriculture and Soil Science
• Analyzes total nitrogen or ammonium nitrogen in soil, plants, and fertilizers to assess soil fertility and plant nutrient status.
• Environmental Monitoring
• Detects pollution indicators such as ammonia nitrogen and total Kjeldahl nitrogen in water bodies, sludge, and sediments.
• Chemical and Pharmaceutical Industry
• Determines the nitrogen content or specific components (such as caprolactam volatile bases) in samples of chemicals, pharmaceuticals, natural rubber, and ores.
