Product Description
The nitrogen purge instrument is a high-precision temperature control instrument controlled by a microcomputer. Its working principle is to blow nitrogen gas to the surface of the heated sample rapidly, continuously and controllably, and set the heating temperature according to the evaporation rate and boiling point of the concentrated solvent to achieve Rapid concentration of large samples.
The instrument adopts an aluminum plate heating module, which has good heat transfer and uniform heat transfer, which is conducive to rapid heating and rapid temperature control. Nitrogen gas is blown onto the sample surface to achieve oxygen-free concentration of liquid samples. The blowpipes are independent of each other and will not cause cross contamination. Each gas needle channel on the gas 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.
