Designed to do fast, precise and flexible protein and nitrogen analysis in the lab, Auto Kjeldahl Analyzer can finish distillation, titration and calculation automatically in 8 minutes and the results will be stored and displayed or printed automatically. The method of color comparison is adopted in the titration system to determine the end point according to the national/international standards (such as AOAC, EPA, DIN, GB) to avoid the complexity of frequent change and calibration of electrodes. It is automatic, stable and dependable, and can ensure safety of lab workers and preciseness of results. The multi-language operation interface makes it easy to learn how to operate the instrument. With a supplemental digestion system and a waste gas absorption system, Hanon is a complete solution of Kjeldahl nitrogen autoanalysis. Features: Officially approved colorimetric titration system (AOAC, EPA, DIN, ISO, GB etc) simplify validation Automatic process including addition of solutions, distillation, titration, calculation, reporting and printing Plunger titration system with precision of 2.4μ L/step. Modern design following ergonomic principles: Assurance of personal safety with a series of security sensors; Completely sealed pipe system to ensure no leakage in distillation; Placement of inclined container to ensure complete assimilation of solution; Intelligent cooling water control system to adjust water flow and reduce costs.
