Automatic Kjeldahl Nitrogen Analyzer JK9830, 0.1-200 mg N (CAT#: STEM-AL2-4125-ZJF)

The JK9830 automatic Kjeldahl nitrogen analyzer is an analytical instrument for determining nitrogen in digested samples. It is intended for Kjeldahl-based nitrogen analysis in laboratory testing workflows. The system manages reagent handling and steam distillation as part of the analytical sequence. Sample ammonia is separated during distillation and transferred to the receiving stage for measurement or titration. Integrated control functions coordinate the analytical steps and reduce manual intervention. The fluid path is configured for repeated exposure to acidic and alkaline reagents used in Kjeldahl analysis. Protection functions monitor operating conditions and help prevent unsafe or incomplete analytical cycles. The instrument is suited to repetitive nitrogen testing where standardized operation and data consistency are required.
