　　1、 Product Introduction of Dry Nitrogen Blowout Instrument:

　　Dry nitrogen blowing apparatus is mainly used for concentration or preparation of large quantities of samples (such as drug screening, liquid phase, and sample preparation in mass spectrometry analysis). Through microcomputer control technology, high-purity aluminum material is used as the heating medium to achieve more accurate temperature control and a wide temperature control range. Its working principle is to blow nitrogen into the surface of the heated sample, causing the solvent in the sample to evaporate and separate quickly, thereby achieving the goal of oxygen free concentration of the sample and keeping it purer.

　　2、 Application fields of dry nitrogen blowing instrument:

　　1. Pesticide analysis: vegetables, fruits, grains, plant tissues, etc

　　2. Pharmaceutical drug testing: Traditional Chinese medicine pharmaceuticals and drug testing

　　3. Environmental analysis: drinking water, groundwater, polluted water, etc

　　4. Bioanalysis: Serum, plasma, blood, urine

　　5. Product inspection: Testing for dioxins, Croats, etc

　　6. Food and beverages: milk, alcohol, liquid beverages

　　3、 Main features of dry nitrogen blower:

　　1. The blowing needles are independent of each other to avoid cross contamination. Optimize gas path control, enhance airtightness, and reduce potential air leakage hazards; Easy to operate, simply lift/press the air needle to achieve channel switching; The switch status of each channel is clear at a glance.

　　2. The height of the air chamber can be adjusted to accommodate different test tubes.

　　3. There are 12 airway control switches that do not waste gas.

　　4. When concentrating toxic solvents, the entire system can be placed in a fume hood.

　　5. Built in over temperature protection device, automatic fault detection and alarm function.

　　6. LED display screen, temperature synchronous display, time decreasing display, easy and convenient operation.

　　7. The heater rapidly heats the sample to the evaporation temperature, while the gas is blown onto the surface of the solution through a gas needle, promoting rapid evaporation of the solution and concentration of the sample.
