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! Package options Cost (including VAT): Digestor, Distiller, Water jet pump 379,400 rubles; Digestor, Distiller, Water jet pump, Scrubber 434,700 rubles; Digestor, Distiller, Water jet pump, Manual titration unit 396,900 rubles; Digestor, Distiller, Water jet pump, Scrubber, Manual titration unit 452,200 rubles; Digestor, Distiller, Water jet pump, Kit «Titrion-pH» (c2) 605,400 rubles; Digestor, Distiller, Water jet pump, Scrubber, «Titrion-pH» kit (c2) 660,700 rubles.

The principle of operation of the magnetization device: The device consists of two compact blocks made of non-magnetic material connected by a flexible magnetic circuit. In each block there is a permanent magnet made of neodymium-iron-boron alloy (Ne-Fe-B). When installing the blocks on the surface of the part, a closed magnetic circuit is formed with the direction of the magnetizing field from one pole to the other. Above the defect scattering fields, magnetic powder particles are deposited to form an indicator pattern. Design features and advantages of the device for magnetic particle control UN-5 The delivery package with the device includes a portable case, an inter-pole jumper installed during transportation, and a liner for fixing blocks with permanent magnets. The UN-5 portable device does not require electrical power and therefore can be used where the supply of stationary power is difficult or impossible under regulatory documents: in the field, when working at height, for inspection of capacitive equipment operating under pressure, etc. - The device is easy to use, lightweight and small-sized, working with it does not require special physical and technical training from the operator; - Flexible magnetic core allows you to use the device to control parts of complex shape; - The UN-5 magnetizing device is distinguished by an increased quality of the indicator pattern and an increased control zone due to a reduced uncontrolled zone near the poles and an improved ratio of the normal and tangential components of the magnetic field (Russian patent No. 60732); - The technical characteristics of the device comply with Russian and foreign regulatory documents, this being the reason of its widespread use in more than 40 countries, including Germany, France, Brazil and Norway. When monitoring, the controlled area is the central part of the area located between the magnetic poles of the device. The width of the monitored area is determined by the width of the magnetic poles of the device and is approximately 60 mm. The length of the monitored section depends on the inter-pole distance. the dimensions of the controlled area are given depending on the device's inter-pole distance: Inter-pole distance, mm 95: 75 55 Controlled area between the working poles, mm: 60x60 40x60 25x55 The length of the defect detection zone depends on the distance established between the working poles of the magnet on the controlled product. Defects are not detected in the areas adjacent to the poles of the magnet. The length of these sections is 18 mm with an interpolar distance of 95 and 75 mm. With an interpolar distance of 55 mm these sections are 13 mm long. Scope of application: Magnetizing devices for magnetic powder flaw detection are used in many industries, including railway, water and aviation transport, in the construction and operation of pipelines, in chemical and petrochemical production. The flexible link between the magnetic blocks allows the control of products of complex shape, for example, cylindrical tanks, high-pressure apparatuses, main pipelines, etc. When checking for defects, the device can be used together with other auxiliary equipment for: - preliminary and subsequent demagnetization; - application of a magnetic indicator (which can be dry or in the form of an emulsion); - magnetoluminescent control (with ultraviolet lamps).
