Description

Kjeldahl Distillation Unit

The Automatic Kjeldahl Distillation Unit is designed to determine the nitrogen content of samples based on the Kjeldahl nitrogen determination method. Fully intelligent software is able to complete sample distillation within minutes, with automatic regent quantification and filling, and automatic test functions. The distillation and condensation automatic cleaning system further enhances measurement precision, and the explicit interface is easy for operation. 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, and can also be used for the test of ammonium, volatile fatty acid/alkali, and so on.
