Digestion Furnace - The Best Guarantee of Kjeldahl

The digester, as its name suggests, is used to digest objects, and is often used in the classic Kjeldahl analyzer. Today, digesters on the market can be divided into two categories: split digital digestion ovens and gradient liquid crystal digestion ovens. Gradient liquid crystal digestion furnace uses temperature gradient timing control to make up for the lack of fixed temperature timing control. Zhejiang Tops KDN-20C Digester This instrument can be arbitrarily set temperature and time, truly realized the purpose of automatic digestion without a person, to ensure the safety of experimental operators.

Zhejiang Top Instrument Co., Ltd. not only produces digester, of course, there are many models of Kjeldahl, ZDDN-II, KDN-08C, KDN-08B, KDN-08A, KDN-04B and other models. Different types of Kjeldahl analyzers correspond to different functional characteristics. However, they can all be applied to experiments in the classic Kjeldahl nitrogen analyzer.

KDN-20C digester, also known as gradient liquid crystal digester, is an instrument that can control the temperature manually, and displays the temperature in real time, now on the microcomputer screen. KDN-20C digestion furnace uses digital display temperature control, set temperature and actual temperature dual display, heating using far-infrared heating, heating speed, and more stable. When the KDN-20C digestion furnace is digested, harmful gases such as SO2 overflowed from the digestive canal without the use of fume hoods, and are discharged into the sewer through an air pump to avoid the pollution of the exhaust gas to the environment and ensure the safety of operators. . The principle of the classical Kjeldahl method is: The protein is a nitrogen-containing organic compound. The food is heated and digested with sulfuric acid and a catalyst to decompose the protein, and the decomposed ammonia is combined with sulfuric acid to produce ammonium sulfate. Then alkalized distillation to ammonia free, absorbed with boric acid and then titrated with sulfuric acid or hydrochloric acid standard solution, according to the consumption of acid multiplied by the conversion factor, which is the protein content. Digestion furnace is the role of digestion in the Kjeldahl method. It is widely used in food, food, feed, soil, fertilizer, water, sediment, chemical dairy products, brewing, sugar, and drugs. , coal, rubber and other substances dissolved.
