Nitrogen Protein Tester


Model: Heidolph

Nitrogen Protein Tester is used in many fields such as food products, animal feed production, and quality control in environmental analysis. The device uses the method of Kjeldahl as a working principle. This method is a standard method which is used for nitrogen fixation. First, nitrogen is transformed into ammonia when the sample is assimilated in sulphuric acid with the help of a catalyser. This ammonia is distilled in capturing solution and the amount of ammonia is determined through solution titration.
