The circular nitrogen blowing instrument uses purge and trapping technology to control the temperature of the sample at the same time, and achieve rapid anaerobic concentration of the sample solution by blowing inert gases such as nitrogen to the surface of the sample quickly, controllably and continuously. This method is time-saving, convenient and accurate. It is widely used in food safety, medicine, pesticide residue testing, clinical pharmacy, and other fields.
Product Specification
Product Features：
- It is suitable for different specifications of test tubes, conical flasks, centrifuge tubes and other containers.
- Number of sample bits: 12 bits /24 digits, the sample holder of the spring test tube clamp is fixed and positioned, and each sample has a numerical number.
- The tube is fixed by a spring-loaded tube clamp and a support disc, and the height direction can be adjusted arbitrarily.
- The freely lifting needle valve tube can be lifted to a suitable height independently according to the size of the test tube and the amount of solvent, and the adjustable needle valve can control the gas flow.
- The circular structure is easy to rotate, which is convenient for the sample holder to enter and exit the water bath, and is easy to operate.
- Intelligent digital thermostat, which can be timed with dual digital displays, and the adjustment adopts PID technology and can realize over-temperature alarm and anti-dry burning.
- All components of the circular nitrogen blower are made of uniform high-quality stainless steel, which can resist organic solvents such as acid and alkali.
- Control valve: Inlet control valve, ensure good air tightness, durable.
- When concentrating toxic solvents, the entire system can be placed in a fume hood.
Applications：
- Pesticide residue analysis: vegetables, fruits, grains, plant tissues, etc
- Pharmaceutical drug testing: traditional Chinese medicine pharmaceutical and drug testing
- Environmental analysis: drinking water, groundwater, polluted water, etc
- Bioanalysis: serum, plasma, blood, urine
- Commodity inspection: test for dioxins, crofts, etc
- Food and beverage: milk, wine, liquid drinks
