Deskripsi Produk	TR-NDK300-1 Nitrogen Concentrator Application:  Analysis of pesticide residues: such as vegetables, fruits, grains, plant tissues. Environmental analysis: water, groundwater and polluted water samples. Bioanalysis: sample preparation in hormonal analysis, liquid phase, gas phase and mass spectrometry. Food and beverage: such as milk, wine, beer, etc. Pharmaceutical drug testing: such as pharmaceutical, drug screening.   Product description: nitrogen purging instrument is a high-precision temperature control instrument formed by the combination of microcomputer processing and PID control. Its working principle is to rapidly, continuously and controlly blow nitrogen gas onto the surface of the heated sample according to the evaporation rate of the concentrated solvent. And boiling point, set the heating temperature to achieve rapid concentration of a large number of samples. The instrument adopts aluminum block heating module, which has good heat transfer and uniform heat transfer, which is convenient for rapid heating and rapid temperature control. Nitrogen gas is blown onto the surface of the sample to achieve anaerobic concentration of the liquid sample. Product features: Synchronously working with heating by dry bath in the bottom and nitrogen blowing on the surface accelerates liquid evaporation and sample concentration. The position of gas needle in air cavity can be adjusted to suit for different types of tubes. The height of the air cavity can be adjusted. The length of a standard gas needle is 150mm. Gas needle is controlled independently. Separately blow of each needle and flow regulating of each needle are available to avoid gas waste. The entire equipment can be put into ventilation cabinet when the concentration sample in toxic solvents. Built in overheat protection, automatic fault detection and fault beep alarm devices. LED display immediate temperature and diminishing time. Operation is simple and convenient. Standard configured air cavity and adjustable bracket.
