Fully-automatic Kjeldahl Analyzer LD-LKA-C11 is a compact and fully automated unit, adopted with distillation and titration function based on classic Kjeldahl nitrogen determination method, offers measuring range of 0.1 to 200 mg N with 5 to 10 min/sample of analysis time. With 2.0 µl/step of burette volume, 5g of solid sample and 20 ml of liquid sample capacity, features pre-install functions of cleaning, i.e., receiving cup cleaning, alkali pipeline cleaning, boric acid pipeline cleaning, acid washing, and steam bottle evacuation. Designed with 4 KNF pumps work for dozing, measurement liquid volume, offers real time detected distilled liquid temperature and high titration accuracy. Equipped with external titration cup, integrated printer and latest core control system, it also has data storage capacity for 1000 groups.
