Product Introduction
Kjeldahl nitrogen distillation apparatus
Suitable for steam distillation of calcium propionate, cation exchange capacity and other items in food, soil and other samples.
Applicable units and testing items:
Environmental monitoring stations at all levels, physical and chemical departments of disease control centers, and hydrological and water resources. Urban water supply and drainage monitoring, research institutes, universities and other water quality testing laboratories at all levels.
Testing items:Volatile phenols, cyanides, ammonia nitrogen, and Kjeldahl nitrogen in water. Distillation pretreatment project for fatty acids and other substances,Distillation pretreatment of items such as oxides and cation exchange capacity in soil.
Main technical advantages:
● Design of built-in cooling water circulation system
Built in compressor with automatic internal circulation, no need for external cooling water, can save a lot of urban freshwater resources, especially for water scarce cities in the central and western regions, which is in line with the development of energy-saving and consumption reducing environmental instruments in China
