Auto Kjeldahl Distillation Unit DW-K9840
DW-K9840 Auto Distiller adopts globally accepted Kjeldahl nitrogen determination method to determine nitrogen content of sample. All intelligent software design makes the sample distillation complete within minutes. The distillation and condensation automatic cleaning system makes the measurement precision further improved.
It is widely used in food processing, feed production, tobacco, livestock, soil fertility, environmental monitoring, medicine, agriculture, scientific research, teaching, quality control and other fields for the test of nitrogen or protein content, can also be used for the test of ammonium, volatile fatty acid/alkali, and so on.
Features
- Adding solutions automatically: automatic adding NaOH solution, acid solution, distillation water.
