The Kjeldahl method is one of the most accurate methods for determining nitrogen and protein in a wide group of products, but, unfortunately, it has a number of significant drawbacks - these are low speed, a large number of possible losses during the analysis, bulky equipment, and the use of aggressive reagents. Sibagropribor Holding presents KELTRUN (KELTRUN) - a set of equipment for carrying out a complete analytical cycle according to the Kjeldahl method, which will allow: • to increase the speed of analyzes (high speed of distillation and ashing, simultaneous processing of several samples); • ensure the safety of personnel (high quality of reaction vessels, effective absorption of acid vapors by the exhaust system, additional protection of personnel in emergency situations); • reduce possible losses in the analysis process; • improve the reproducibility of results. «KELTRAN» (KELTRUN) will allow you to determine nitrogen / protein in the widest list of substances: • food products: dairy, cereals, meat, cereals, etc.; • feed and compound feed; • fertilizers; • water, drinks, beer; • soil, bottom sediments, sediment samples, activated sludge; • crude oil, lubricants; • various chemicals; • alcohol content in wines, musts and spirits; • etc. The set of equipment «KELTRAN» (KELTRUN) allows you to analyze according to GOST and determine the nitrogen content in the range of 0.02 - 99.00%. Composition of the complex «KELTRAN» (KELTRUN): - Digestor; - Distiller; - Scrubber (*not included in the price of the complex); - Titration unit: manual, semi-automatic or automatic (*not included in the price of the complex); Warranty - 1 year. Important feature! In many distillers (made in China and others), when used, alkali passes through a valve-type pump, with a low production resource (sometimes the resource is enough for only 3 months). In the distiller of our production, the alkali passes through a RELIABLE PERISTALTIC PUMP, this ensures a long service life of the distiller!
