DHN200-2
Dry Nitrogen Blower
Temperature control range is from room temperature +5℃ to 150℃, with 24 airway control switches.

Dry Nitrogen Blower, also known as nitrogen blowing concentrator or nitrogen evaporator, is mainly used for the concentration or preparation of large quantities of samples under anaerobic conditions. It is widely used in pesticide residue analysis, commodity inspection, food, environmental, pharmaceutical, and biological product industries. The nitrogen concentrator adopts microcomputer control technology, and the heating is achieved by using high-purity aluminum material as the heating medium, which provides fast heating and more accurate temperature control with a wide range. DHN200 can handle 12 sets of samples simultaneously, and the manufacturer also offers various types of nitrogen concentrators such as water bath nitrogen concentrator, circular nitrogen concentrator, and visible nitrogen concentrator for customers to choose from.

Background
"Multiresidue Rapid Screening Method (MRSM) for Pesticides in Agricultural Products and Environment" is an international advanced agricultural science and technology project introduced and implemented by the Institute of Environment and Sustainable Development in Agriculture of the Ministry of Agriculture and the General Station of Agricultural Environment Monitoring of the Ministry of Agriculture. The "Detection Method of Melamine in Raw Milk and Milk Products" GB/T 22388-2008 issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Standardization Administration of China on 2008-10-07 requires the use of a nitrogen blow-drying instrument for the pretreatment of melamine in milk and other dairy products: see section 3.3 of this detection method for the instruments and equipment used.

Product Features
1. Each blowing needle can be controlled independently to avoid cross-contamination.
2. The height of the instrument's air chamber can be adjusted, and it is equipped with a standard gas needle with a length of 15cm.
3. DHN200 nitrogen blower has 12 airway control switches to save gas. The position of each blowing needle can be independently changed to adapt to different sample containers and sample positions.
4. When concentrating toxic solvents, the entire system can be placed in a fume hood to reduce danger.
5. Built-in over-temperature protection device, automatic fault detection and alarm function, convenient and practical.
6. The instrument has an LED display screen, which synchronously displays temperature and time decrement, allowing real-time observation of temperature changes.
7. The dry nitrogen blower has more uniform temperature and faster heating speed.
8. This product can also be used as a general dry constant temperature device.
9. DHN200 is a dry nitrogen blower, which is easier to use and can achieve a temperature of up to 150°C, making it better for sample concentration.

Application areas
Analysis of pesticide residues: such as vegetables, fruits, grains, and plant tissues;
Environmental analysis: such as drinking water, groundwater, and polluted water samples;
Biological analysis: such as hormone analysis, sample preparation in liquid, gas and mass spectrometry analysis;
Food and beverage analysis: such as milk, wine, beer, etc;
Pharmaceutical testing: such as traditional Chinese medicine, drug screening.
