introduction：jxdc-400 series nitrogen purging instrument is a high-precision temperature control instrument formed by the combination of microcomputer processing and pid control.
the jxdc-400 series 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 blow nitrogen to the surface of the heated sample quickly, continuously and controllably, according to the concentration of the solvent. evaporation speed and boiling point, set heating temperature, realize rapid concentration of a large number of samples.
this instrument uses an aluminum plate heating module, which has good heat transfer and uniform heat transfer, which is conducive to rapid heating and rapid temperature control. blow nitrogen to the surface of the sample to achieve oxygen-free concentration of the liquid sample. the blowpipes are independent of each other and will not cause cross-contamination. the air needle channels on the air distribution assembly can be used in combination or individually. the system has high temperature control accuracy, wide temperature control range, temperature numerical control digital display, and convenient temperature calibration. the product has beautiful appearance, simple operation, safe and reliable use.
the main application areas of this product:
★ 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
◆the gas needles are independent of each other and will not cause cross-contamination.
◆the flow rate of each gas needle can be adjusted individually
◆the blowpipe channels can be used in combination or individually.
◆each air needle flow control valve corresponds vertically to the module hole position, and the adjustment is intuitive and convenient.
◆the system has high temperature control accuracy, wide temperature control range, and convenient temperature calibration
◆the lifting components are equipped with independent positioning safety bolts, which are safe for long-term use.
