Steam Distillation Unit for Kjeldahl Nitrogen

凯氏氮蒸汽蒸馏装置

Once digestion is done, this unit dispenses 0–100 mL alkali automatically, steam-distils ammonia into boric acid or standard acid and can titrate by potentiometric or colorimetric endpoint. Each sample takes 3–6 min, so expect 20–40 samples/h. Steam rate adjusts from 30 to 100 percent, and the range covers 0.1–200 mg N.
