Introduction: The KD200 visual nitrogen blower is mainly used for the concentration preparation of large batches of samples, such as sample preparation in drug screening, hormone analysis, liquid phase, gas phase and mass spectrometry analysis. Working principle: By blowing nitrogen into the surface of the heated sample, the solvent in the sample is quickly evaporated and separated, so as to achieve the purpose of anaerobic concentration of the sample and keep the sample more pure. Using a nitrogen blower to replace the commonly used rotary evaporator for concentration can concentrate dozens of samples at the same time, greatly shortening the sample preparation time, and has the characteristics of time saving, easy operation and fast. Features 1. The heater enables the sample to be quickly and efficiently heated to the evaporation temperature, and at the same time the gas is blown from the gas chamber to the surface of the solution through the gas needle to promote rapid solution evaporation and sample concentration 2. Each purge needle can be controlled independently, can be purged separately, and the flow rate can be adjusted independently without wasting gas 3. The position of the gas needle in the gas chamber can be changed to make it suitable for different test tubes. The standard gas needle length is 150mm 4. The height of the air cavity can be adjusted, this product has unique characteristics: the liquid level of the concentrated sample can be observed at any time when the sample is concentrated 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 Technical Parameters: 1. Temperature control range: room temperature + 5 ℃ ~ 150 ℃ 2. Temperature stability: ≤ ± 1 ℃ (room temperature + 5 ℃ -100 ℃) ≤ ± 1.5 ℃ (100 ℃ -150 ℃) 3. Heating time (from 40 ℃ to 150 ℃): ≤30min 4. Time setting: 1min-99h59min 5. Power supply: 400W 6. Temperature control accuracy: 0.1 ℃ 7. Gas needle length: 150mm 8. Sample capacity: 12 9. Dimensions (L × W × H): 280 × 240 × 500mm
