The water bath nitrogen purging instrument independently developed, designed and produced by Shanghai Yuncao adopts the purging and trapping technology, and can control the temperature and heat the sample at the same time. Inert gases such as nitrogen are used to rapidly, controllably and continuously blow to the sample surface to achieve rapid oxygen free concentration of the sample solution. This method is time-saving, convenient and accurate. It is widely used in food safety, medicine, pesticide residue detection, clinical pharmacy and other fields.

Shanghai round water bath nitrogen blowing instrument and dry bath nitrogen blowing instrument are two common nitrogen blowing instruments. The differences between them are reflected in the heating module, temperature range, application range, etc.

The circular electric lifting nitrogen purging instrument YCYN-DCY-12SL, independently developed, designed and produced by Shanghai Yuncao, adopts the approved technology, and uses the purging and trapping technology. At the same time, it can control the temperature and heat the sample, and achieve rapid oxygen free concentration of sample solution by rapidly, controllable and continuously blowing inert gases such as nitrogen to the sample surface. This method is time-saving, convenient and accurate. It is widely used in food safety, medicine, pesticide residue detection, clinical pharmacy and other fields. 1. Pesticide residue analysis: vegetables, fruits, grains, plant tissues, etc 2. Pharmaceutical and drug inspection: traditional Chinese medicine and drug inspection 3. Environmental analysis: drinking water

The concentration method adopted by Yuncao full-automatic nitrogen blowing instrument has greatly improved the concentration rate in a large amount of analysis work, especially in the field of environmental pollutants and food safety analysis. At the same time, the equipment uses its own exhaust fan to discharge the evaporated waste gas directionally from the exhaust pipe, so that the nitrogen blowing concentration device that must be placed in the ventilation kitchen can be safely installed on the general experimental platform. It is not only easy to move and save laboratory costs, but also greatly reduces the harm of toxic and harmful solvents to operators. It is the sample pretreatment device of the laboratory.

Application field of visible nitrogen blowing instrument ★ Pesticide residue analysis: such as vegetables, fruits, grains and plant tissues ★ Environmental analysis: drinking water, groundwater and polluted water samples ★ Biological analysis: such as sample preparation in hormone analysis, liquid phase, gas phase and mass spectrometry ★ Food and beverage: such as milk, wine, beer, etc ★ Pharmaceutical and drug inspection: such as traditional Chinese medicine and drug screening
