Laboratory Automatic kjeldahl nitrogen analyzer for protein anaysis
Auto Kjeldahl Nitrogen Analyzer is perfessional instrument which used to analysis protein content and nitrogenious compounds in nature.It widely used fast protein analysis in filed of Food,Milk,Meat,Drink,Medicine,Soil and feed.
LKN9830 Kjeldahl semi-auto analyzer is an auto analyzer which with characters including auto reagent addition, auto distillation and separation of sample, auto collection of samples and auto termination of distillation; the separation methods which adopted by the LKN9830 is 100% corresponds to the National and International standards.
* 6 inch LCD display.
* Manual/automatic mode can be switched freely.
* Siemens control system, with high precision and stability.
* 10 groups of programs, meet the demand of different customers.
* Automatic control of adding alkali and boric acid solution, dilution and elution.
* Multi-protection function,such as safety door, overpressure protection, water shortage protection,etc.
Features:
1. Manual/auto double-mode switch and automatically adding quantitative alkali liquor and boric acid absorbent solution
2. 10 experimental procedures can be stored to meet users' different requirements. Distillation time can be set at will. After distillation completion, it will give an alarm automatically.
3. Automatic cleaning system realizes intelligent pipeline cleaning function which make measuring accuracy higher.
4. Perfect safety protection system can measure and protect over-temperature and over pressure of distiller and pipeline.
