Automatic Kjeldahl Analyser BKN-986
An Automatic Kjeldahl Analyser is a specialized laboratory instrument used for rapid, precise determination of nitrogen and protein content in organic materials. It fully automates digestion, distillation, and titration—reducing human error, labor, and time. It is widely used in food, feed, agricultural, and environmental industries.
Key Uses and Applications
Protein Determination: Used extensively to measure protein content in food processing (meat, dairy, nuts, grains) and raw materials.
Nitrogen Analysis: Used for testing fertilizer composition, animal feed, soil fertility, plant tissue, and beer/beverage QC.
Environmental Monitoring: Determines nitrogen levels in wastewater, sediment, and chemical samples.
Industrial Applications: Used in tobacco research, rubber, and latex analysis.
Key Features of Automatic Analyzers
Automated Processes: Includes automatic reagent dosing (water, acid, alkali), distillation, titration, data storage, and cleaning.
High Efficiency: Features high-speed titration (approx. 40 ml/min) and rapid distillation (5-15 mins per sample).
Safety & Data Management: Equipped with safety shields, automatic cleaning to prevent sample cross-contamination, and storage for thousands of test records.
Cloud Connectivity: Some models allow remote monitoring and data management.
