product description:
JXDC-20 nitrogen purging instrument adopts microcomputer and PID fuzzy control technology, and uses high-purity aluminum material as the heat transfer medium to replace the traditional water bath device. It has the characteristics of convenient use, large temperature control range, and high precision. Its working principle is to blow nitrogen or air to the surface of the heated sample quickly, continuously and controllably, and set the heating temperature according to the evaporation speed and boiling point of the concentrated solvent to achieve rapid concentration of a large number of samples.
Features:
◆ The blowpipes are independent of each other and will not cause cross-contamination;
◆ Each air needle channel can be used in combination or alone;
◆ The system has high temperature control accuracy, wide temperature control range, temperature numerical control display, and temperature calibration is convenient;
◆ The product has beautiful appearance, simple operation, safe and reliable use;
