Automatic kjeldahl analyzer Kjeldahl protein analyzer
NB2000 Kjeldahl Auto Analyzer with auto feeder / auto sampler is our independent research and development,product with 100% independent intellectual property rights. It is based on the basic theory research and development of Kjeldahl method.
It's namely that sample digestion process is still using the traditional "Kjeldahl" heat, digestion method; The sample separation still heating, distillation and volatile under conventional alkalifying conditions; sample collection is still using a weak acid solution absorption, but the sample analysis process is accomplished under "standard curve". After long-term multi-sample comparison (different standard substances, samples in different industries, different content of the sample), analysis results with traditional methods but the same analytical precision 6 times higher than traditional methods, up to 0.05mg N. Therefore, the series of products are consistent with national and international standards which relevant to Kjeldahl nitrogen (except for certain industries.
This technology won a number of national patents and also passed the national scientific and technological achievements identification, appraisal, the conclusion is "Leading to the International Level". This product also won the Golden Medal in 2011 which issued by the "China Association for Instrumental Analysis BCEIA", won the Innovation Silver Award in the 10th China International instruments and laboratory equipment exhibition ", it gained the fund in 2011 which issued by Ministry of Science and Innovation Fund Projects and technological achievements, it won the 2011 Shandong Province Science and Technology Progress Award 3, and etc.
This series is an unattended and 100% automatic Kjeldahl Analyzer, 60 samples can be placed for analysis, and the whole process without care. The analyzer power is 200w, energy saving 80% than traditional instruments. The whole process of analysis without tap water for cooling, water saving is 99% than traditional instruments. Samples of each reagent consumption is 60% less than traditional products, all accessories for the analyzer are market general-use ones, therefore it's easy for forming a complete set (42 Φ digestive tube).
Performance Advantages
- New appearance design. Shaping one time and cambered in design and manufacture ensuring the appearance artistic, clean and modernistic.
- Maintenance-Free Structure. Through a hardware upgrade by replacing the original Peristaltic pump injection to metering pump injection, the analyzer without having to be replaced regularly to maintain the pump tube.
- Full-Automatic Operation System. Auto sampling, reagents adding, sample heating, separation, sample absorption analysis and calculation, data storage, waste discharge of waste can be easily accomplished by just a "Click" on button; and advance to the next sample program automatically.
- Screen / Display. 7 inches color touch screen, bilingual operating system (Chinese & English Free Switch).
- Patented Technology Application
- Sub-boiling distillation separation technology is able to save 80% energy than the traditional instruments which meets the energy-saving requirements, thus reducing expenses for customers. Air-cooling technology makes the entire analysis process with no water (for cooling purpose) being involved, it may save 99% water than the traditional instruments, that meets national and international tendency of water resources saving.
- A sample of each reagent consumption is less 40% than traditional instruments, which not only reduces the secondary pollution, but corresponds to environmental requirements as well.
- Appliance of standard curve analysis technology, makes the accuracy is 6 times higher than the traditional instruments, thus the precision reaches 0.05mg N, which corresponding to trend of high-precision and high-tech.
- Subvert the traditional technology of oversea patent application which corresponding to the orientation of innovation which advocated by Nation, and provide technical support for the future establishment of relevant national standards, therefore accumulate precious experiences for the upcoming Chinese technical-based drafting products' standards.
- Patented Technology. Japan-Based Omron PLC board application adequately ensures the instrument's reliability and stability in operation.
- Adopt the US company CPC quick intubation liquid supply system to ensure no leakage and extend instrument life.
- All pipes are the US-Based modified silicon gal tubes, therefore the headache of leakage and corrosion which caused by pipe-aging have been completely eliminated.
- System Clean-Up. To prevent cross-contamination, the instrument is with its own a cleaning system for customers to ease work.
Safety & Protection System
- Leakage Protection. It's able to prevent leakage due to system damage caused by user and / or any unexpected, thus protect user's safety of body at utmost.
- Over temperature protection system. The over temperature protection system is composed of temperature sensor and CPU, which is able to prevent overheating phenomena due to system failure or other issues effectively, then ensure that user easy to work with.
