Nitrogen blower

Dry-Type Nitrogen Sample Concentrator DHN200-2 is the abbreviation of nitrogen concentration device and nitrogen purging instrument, which is mainly used for the concentration or preparation of large quantities of samples in the absence of oxygen.

It is widely used in pesticide residue analysis, commodity inspection, food, environment, pharmaceutical, biological products and other industries. The nitrogen blower is controlled by microcomputer technology, and the heating is made of high-purity aluminum material as the heating medium. The heating speed is fast and the temperature control is more accurate. , Wide temperature control range, DHN200 can process 24 groups of samples at the same time, the manufacturer also provides various types of nitrogen blower, such as water bath nitrogen blower, circular nitrogen blower, visual nitrogen blower, etc. Customers can choose by themselves.

1. Each blowing needle can be independently controlled to avoid cross-contamination.

2. The height of the air chamber of the instrument can be adjusted by itself, and the length of the standard air needle is 15 cm.

3. The DHN200 nitrogen blowing instrument has 24 airway control switches to save gas. The position of each blowing needle can be changed independently to make it suitable for different sample containers and different sample positions.

4. When concentrating toxic solvents, the whole system can be placed in a fume hood to reduce the risk.

5. Built-in over-temperature protection device, automatic fault detection and alarm function, convenient and practical.

6. The instrument has an LED display, the temperature is displayed synchronously, and the time is displayed gradually, so that the temperature change can be observed from time to time.

7. The dry nitrogen blower has a more uniform overall temperature and fast heating speed.

8. This product can also be used as an ordinary dry thermostat.

9. DHN200 is a dry nitrogen blowing instrument, which is easier to use, and the temperature can reach 150 ℃, which can better concentrate the sample.

Application fields of Dry-Type Nitrogen Sample Concentrator:

Pesticide residue analysis: such as vegetables, fruits, grains, plant tissues; 

Environmental analysis: such as drinking water, groundwater and polluted water samples; 

Biological analysis: sample preparation in hormone analysis, liquid phase, gas phase and mass spectrometry; 

Food and beverages: such as milk, wine, beer, etc.; 

Pharmaceutical drug testing: such as traditional Chinese medicine, drug screening.
