Product name: Water bath nitrogen blowing instrument
Product model: DN series
Product Details
product manual:
Water bath nitrogen blowing instrument is used for sample preparation in gas phase, liquid phase and mass spectrometry analysis. It uses internationally recognized technology to concentrate the sample by blowing nitrogen into the surface of the heated sample. This method has the characteristics of time-saving, convenient operation, easy control, etc., and the expected result can be obtained quickly. This technology uses solid-phase extraction pre-treatment technology to replace traditional liquid-phase extraction and chromatography technology, so that samples can be quickly separated and purified. Using nitrogen blowing instead of a common rotary evaporator for concentration, greatly shortens the analysis time.
Use field
Main application areas of nitrogen blowing instrument:
★ Pesticide residue analysis: such as vegetables, fruits, grains, plant tissues
★ Environmental analysis: such as drinking water, groundwater and polluted water samples
★ Biological analysis: such as sample preparation in hormone analysis, liquid phase, gas phase and mass spectrometry analysis
★ Food and beverages: such as milk, wine, beer, etc.
★ Pharmaceutical drug testing: such as traditional Chinese medicine, drug screening
Main features:
●The height of the nitrogen blowing box is adjustable and easy to operate.
●The front drain valve is convenient to replace the medium.
●The test tube rack with nitrogen blowing in the water bath can easily move the test tube out or into the water tank.
●Accurate temperature control, digital display, automatic temperature control.
