product description

JXDC-400The series nitrogen purging instrument adopts microcomputer processing andPIDHigh precision temperature control instrument formed by combining control methods,Its working principle is to rapidly, continuously, and controllably blow nitrogen gas onto the surface of the heated sample, set the heating temperature according to the evaporation rate and boiling point of the concentrated solvent, and achieve rapid concentration of a large number of samples.

This instrument adopts an aluminum plate heating module, which has good heat transfer and uniform heat transfer, which is conducive to rapid heating and temperature control. Blow nitrogen onto the surface of the sample to achieve anaerobic concentration of the liquid sample. Blow pipes are independent of each other and will not cause cross contamination. The gas needle channels on the gas distribution component can be used in combination or separately. The system has high temperature control accuracy, wide temperature control range, temperature numerical control digital display, and convenient temperature calibration. The product has a beautiful and elegant appearance, simple operation, safe and reliable use.

Product features:

The air needles are independent of each other and will not cause cross contamination.

Each needle flow rate can be adjusted individually

Each blowing tube channel can be used in combination or separately.

Each air needle flow control valve corresponds vertically to the module hole position, making adjustment intuitive and convenient.

The system has high temperature control accuracy, wide temperature control range, and convenient temperature calibration

The lifting component is equipped with an independent positioning safety bolt, which is safe for long-term use.
