Shanghai Xinjia Electronics Intelligent Nitrogen Fixing Device KDN-CZ

Product Description

1、The nitrogen fixing instrument for determining the protein content in the sample is designed and manufactured according to the Kjeldahl principle. The instrument mainly consists of two operating steps: digestion and distillation of the sample. The first half of the process is carried out by the digestion furnace, and the second half of the working process is completed by the distiller.； The cooled digestive tubes are placed one by one on the distillation meter, diluted with water, added absorbent liquid to the receiving bottle, added alkali and started distillation, and finally calculated the protein content of the sample being tested from the titration solution.

2、KDN-CZ Intelligent nitrogen fixing instrument product, C The temperature of the digester can be adjusted at will and displayed digitally. The built-in structure is classic, and the selection of materials with the best heat effect can make it obtain good digestion and detection results. When digesting the sample, weigh the sample (usually within 1 gram), add concentrated sulfuric acid and catalyst (adding the catalyst can accelerate the sample digestion and decomposition process and shorten the digestion time), and escape during the digestion process. CO2、SO2 The harmful gases are discharged into the sewage channel through the sewage pipe through the three-way exhaust flow water, which can effectively suppress the escape of harmful gases.

3、KDN-CZ The working water of the nitrogen fixing instrument (distiller) uses tap water. The instrument is turned on and is in intelligent humanized control (built-in flow-limiting control board) so that the instrument is in a working state in the shortest time. The sample is distilled by steam, so that the ammonium sulfate produced during the digestion process is converted into ammonia and reacted with boric acid to form ammonium biborate. The distillation process of one sample is 5 ~7The distillation process can be completed in about minutes. A timed receiving liquid receiving device is also installed inside to improve working efficiency, and the main working parts are ABS Anti-corrosion material.
（Note: Digestion furnace can be equipped with other models according to actual conditions)
