Shanghai Haozhuang brand nitrogen blower adopts purge and trap technology

Shanghai Haozhuang Instrument Co., Ltd. develops the LNB brand nitrogen blower, which is energy-saving and environmentally friendly, leading the country. Shanghai Haozhuang Instrument Co., Ltd. is an enterprise specializing in scientific instrument R & D, production, sales and service. The main products are laboratory instruments such as nitrogen blowing instrument, water bath nitrogen blowing instrument, visible nitrogen blowing instrument, low temperature constant temperature series, shaker, incubator and so on. The nitrogen blower produced by our company adopts purge and trap technology, and uses the inert gas of nitrogen to blow to the surface of the sample quickly, controllably and continuously to achieve the rapid separation, purification and anaerobic concentration of samples containing unknown and various types. This method is time-saving, convenient and accurate. The visible nitrogen blower is mainly used for the concentration preparation of large-scale samples, such as sample preparation in drug screening, hormone analysis, liquid phase, and mass spectrometry analysis.

The role of nitrogen blowing instrument: 1. Pesticide analysis: vegetables, fruits, grains, plant tissues, etc. 2. Pharmaceutical drug testing: Chinese medicine pharmacy and drug testing 3. Environmental analysis: drinking water, groundwater, contaminated water, etc. 4. Biological analysis: serum, Plasma, blood, urine 5. Commodity inspection: inspection of dioxin, croft, etc. 6. Food and beverage: milk, wine, liquid beverages visible nitrogen blower features: 1. The heater makes the sample heated quickly and effectively To the evaporation temperature, at the same time, the gas is blown from the gas chamber to the surface of the solution through the gas needle, which promotes the rapid evaporation of the solution and the concentration of the sample 2. Each purge needle can be independently controlled, and the purge can be carried out independently, and the flow rate can be adjusted independently without gas waste. The position of the air needle in the air cavity can be changed to make it suitable for different test tubes. The standard air needle length is 150mm 4. The height of the air cavity can be adjusted, this product has unique characteristics: the concentrated sample can be observed at any time when the sample is concentrated The liquid level position 5. When concentrating toxic solvents, the entire system can be placed in a fume hood 6. Automatic fault detection and alarm function 7. Standard equipped with air cavity and special adjustable bracket 8. Built-in over-temperature protection device 9. Instant temperature Obvious The performance index of the visible nitrogen blower is shown in the display and time decreasing: 1. Temperature range: room temperature + 5 ℃ ~ 150 ℃ 2. Heating time: ≤30min (from 40 ℃ to 150 ℃) 3. Temperature accuracy @ 40 ~ 100 ℃: ± 1 ℃ 4. Temperature accuracy @ 100 ~ 150 ℃: ± 1.5 ℃ 5. Temperature stability @ 100: ± 1 ℃ 6. Number of modules: 1 piece 7. Display accuracy: 0.1 8. Longest time setting: 99h59min 9. LED display 10. Nitrogen flow rate: 0 ~ 10L / min 11. Nitrogen pressure: ≤0.1MPa The nitrogen blower uses inert gas to purge the heated sample liquid, so that the sample to be processed can be quickly concentrated to achieve the effect of rapid separation and purification. This method is easy to operate, especially can process multiple samples at the same time, greatly reducing the detection time. It is widely used in pesticide residue testing, batch processing of samples in the pharmaceutical industry and general research.

Welcome customers!

LED (Light Emissions Device) Letters are very common and popular advertising methods in the recent years. LED Letters can be customized in any font or color you want to attract more customers for your shop/company.                            

Usually, we use good quality LED in [Strip & Module" and LED can be used both Inside and outside of the Led Letters to make it glow.

Generally Structure of the LED Letter signage is made up with 1mm-2mm thick galvanized, Stainless Steel, or Aluminium,  dually coated with primer to avoid rusting. The sides of frame are covered with same sheet with the support between the frames depends on size of the frame. The front side can be of Acrylic or any other media.


We-Smart Sign, with the help of Experienced & skill workers & modern machine, are committed to customer`s  satisfaction with the most economical cost of LED Letters.
