Shanghai Xinzhuang Instrument Co., Ltd. is a professional enterprise engaged in research, development, production, sales and service of scientific instruments. The main products are nitrogen blowing instrument, water bath nitrogen blowing instrument, visible nitrogen blowing instrument, low temperature constant temperature series, shaker, incubator and other laboratory instruments. The nitrogen blowing instrument produced by our company adopts the purging and trapping technology, and uses the inert gas of nitrogen to blow to the surface of the sample quickly, controllly and continuously to reach the sample containing unknown and multi-class, and quickly obtain separation, purification and anaerobic concentration. This method is time-saving, convenient and accurate. Visible nitrogen blowing instruments are mainly used for concentrated preparation of large quantities of samples, such as drug screening, hormone analysis, liquid phase, and sample preparation in mass spectrometry. 
Visible Nitrogen Blowing Apparatus: 1. The heater heats the sample to the evaporating temperature quickly and efficiently, and the gas is blown from the gas chamber to the surface of the solution through the gas needle to promote rapid evaporation of the solution and concentration of the sample. 2. Each purging needle can be independently Control, can be separately purged, flow adjustment alone, no waste of gas 3. The position of the gas needle in the air chamber can be changed to make it suitable for different test tubes. The standard gas needle length is 150mm 4. The air chamber height can be adjusted, This product has a unique feature: the liquid level of the concentrated sample can be observed at any time when the sample is concentrated. 5. When the toxic solvent is concentrated, the whole system can be placed in the fume hood. 6. Automatic fault detection and alarm function 7. Standard gas Cavity and special adjustable bracket 8. Built-in over-temperature protection device 9. Instant temperature display, time decrement display performance index of visible nitrogen blowing instrument: 1. Temperature range: room temperature +5 °C ~ 150 °C 2.2 Heating time: ≤ 30min ( From 40 ° C to 150 ° C) 3. Temperature accuracy @ 40 ~ 100 ° C: ± 1 ° C 4. Temperature accuracy @ 100 ~ 150 ° C: ± 1.5 ° C 5. Temperature stability @ 100: ± 1 ° C 6. Number of modules: 1 piece 7. Display accuracy: 0.1 8. Time setting is the longest: 99h59min 9. LED display 10 Nitrogen flow rate: 0~10L/min 11. Nitrogen pressure: ≤0.1MPa Nitrogen blowing instrument uses inert gas to purify the heating sample, so that the sample to be treated is quickly concentrated to achieve rapid separation and purification. The method is easy to operate, in particular, it can process multiple samples at the same time, which greatly shortens the detection time. It is widely used in batch processing of pesticide residues, pharmaceutical industry and general research.
The role of nitrogen blowing instrument: 1. Analysis of pesticide residue: vegetables, fruits, grains, plant tissues, etc. 2. Pharmaceutical drug testing: Chinese medicine pharmaceutical and drug testing 3. Environmental analysis: drinking water, groundwater, polluted water, etc. 4. Biological analysis: serum, Plasma, blood, urine 5. Commodity inspection: testing dioxins, Croft, etc. 6. Food and beverage: milk, wine, liquid beverages.
