Introduction: The DC150-2 nitrogen blowing instrument is a high-precision temperature control instrument formed by the combination of microcomputer processing and PID control. Its working principle is to rapidly, continuously and controlly blow nitrogen gas onto the surface of the heated sample according to the evaporation rate of the concentrated solvent. And boiling point, set the heating temperature to achieve rapid concentration of a large number of samples. The instrument adopts aluminum heating module, which has good heat transfer and uniform heat transfer, which is convenient for rapid heating and rapid temperature control. Nitrogen gas is blown onto the surface of the sample to achieve anaerobic concentration of the liquid sample. Features: 1. The gas needles are independent of each other and will not cause cross-contamination. 2, each gas needle flow size can be adjusted separately 3. Each blowpipe channel can be used in combination or separately. 4. Each gas needle flow regulating valve and the module hole position are vertically corresponding, and the adjustment is intuitive and convenient. 5, system temperature control accuracy, temperature control range, temperature calibration is convenient 6. The lifting mechanism has safety protection devices and is safe to use. 7. The lifting mechanism is displayed with a scale, and the positioning is accurate and clear. Technical Parameters: Product model: DC150-2 nitrogen blowing instrument Temperature range: room temperature +5 ° C - 150 ° C Heating time: ≤30min (from 20°C to 150°C) Temperature stability @40: ≤±0.3°C Temperature stability @100: ≤±0.5°C Temperature stability @120°C: ≤±1°C Number of modules placed: 2 Timing time setting: 0-99h59min Nitrogen flow rate: 0-12L/min Nitrogen pressure: ≤0.2MPa Maximum power: 400W Dimensions: 220x290x540mm
