The role of the nitrogen blower is to promote rapid solution evaporation and sample concentration
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 wasting gas3 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 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 display, time decreasing display performance indicators of visible nitrogen blower: 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: 0 ~ 10L / min 11. Nitrogen pressure: ≤0.1MPa 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.
The company actively introduces new technologies, new processes, and uses branded raw materials and components to design, manufacture and produce a series of environmentally friendly and energy-saving laboratory instruments in accordance with industry standards. In the future, we will continuously improve the management level, scientific innovation, excellence and the optimization of the talent team to provide more high-quality new products for the majority of users.
50X100mm 3D Wire Mesh Fence is also known as 3D bending fence curvy welded fencing, triangle mesh fence,, etc. Triangle bend fence is pretty light yet durable
Wire mesh fence is a type of fencing made from wire mesh that is commonly used for security and containment purposes. It is made up of a series of wires that are woven or welded together to create a mesh pattern.
Wire mesh fence is often used for perimeter security, as it provides a strong barrier that is difficult to climb or cut through. It is also commonly used for animal containment, such as in agricultural settings. Wire mesh fence can be installed in a variety of configurations, including as a standalone fence or as a component of a larger security system.
