LT-840 Aging water bath

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!

The mixer operates in a speed range from 50 to 1500 rpm, the maximum heating temperature of the working surface is 500 °C. The heating plate includes a base made of stainless steel and a working surface made of fire-resistant glass (glass ceramics). At temperatures above +550 °C, automatic overheating protection is triggered and turns off the heating. The device is equipped with an LCD screen to display set and actual temperatures, rotation speeds and additional animated icons. There is a timer for the specified operating time of the mixer; its maximum value is 990 minutes. There is a function for automatic detection of armature rotation failure. When the device detects an armature failure, the rotation stops. Then rotation resumes, but the speed is reduced by 10%, followed by restoration of the rotation speed to the user-specified parameters. A stall occurs if the armature becomes disengaged with the stirrer magnet and stops rotating. Disruption can occur for various reasons: the rotation speed is too high, the viscosity of the medium has changed during the mixing process, etc. When the power of the device is turned off, the set values of temperature, speed, timer time and the mode of detection (determination) of failure of armature rotation are stored in non-volatile memory. The armature rotation speed and heating temperature are set using two rotating knobs.

The UNM-1000 AC flaw detectors allow monitoring of products by the applied field method using various magnetization techniques. To do this, the alternating electric current generated by the flaw detector can be passed through a magnetizing cable or directly through a controlled product connected to the flaw detector using electrical contacts.
