The nitrogen blow dryer is used for sample preparation in liquid phase, gas phase, and mass spectrometry analysis. It adopts internationally recognized technology, usually blowing nitrogen into the surface of heated samples for sample concentration. This method has the characteristics of time-saving, easy operation, and easy control, and can quickly obtain the expected results.

QF-3800Structural characteristics of nitrogen blowing concentration device:

1. The QF-3800 nitrogen blowing device has good heat transfer performance, uniform heat transfer, and is conducive to rapid heating and temperature control.

2. Blow nitrogen onto the surface of the sample to achieve anaerobic concentration of the liquid sample. Blow pipes are independent of each other and will not cause cross contamination.

3. QF-3800 has multiple hole numbers and corresponding blowing needles to choose from.

4. The QF-3800 is specially designed with a water receiving box to prevent accidental spillage of liquid during operation, in order to prevent damage to the internal circuit.

5. The overall temperature is more uniform and accurate, and the temperature will also be directly detected by sensors.

6. Four sets of digital displays respectively show the set temperature and actual temperature of the device.

7. A well-designed internal structure of the instrument allows it to operate at a relatively high constant temperature for a long time
