Kjeldahl Nitrogen/Protein Analyzer

The Instrument:

Kjeldahl method was specifically developed by Danish chemist, Johan G.C.T. Kjeldahl, in 1883 to determine the nitrogen contents in organic and inorganic substances (like foodstuffs, plants, fertilizers, wastewater, soil, feed, grain, and many other substances). This method is also used for estimating the protein content in food.

Make: Velp Scientifica
