product description:

The visible 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 quickly, continuously and controllably to the surface of the heated sample, according to the concentrated solvent The evaporation speed and boiling point of the product, the heating temperature is set, and the rapid concentration of a large number of samples is realized.

Features:

The visible 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 evaporation speed of the concentrated solvent And the boiling point, set the heating temperature to achieve 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. Each test tube hole has a slot, which is convenient for users to observe the sample concentration status in real time. 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.
