Nitrogen purging instrument JN300-1
The nitrogen purging instrument adopts the microcomputer control technology, uses the high purity aluminum material as the heat conduction medium, instead of the traditional water bath device. Its working principle is to nitrogen or air fast, continuous and controllable blowing to the heating of the sample surface, and according to the concentration of solvent evaporation rate and the boiling point

 

The nitrogen purging instrument adopts the microcomputer control technology, uses the high purity aluminum material as the heat conduction medium, instead of the traditional water bath device. Its working principle is to nitrogen or air fast, continuous and controllable blowing to the heating of the sample surface, and according to the concentration of solvent evaporation rate and the boiling point, set the heating temperature, concentration or for preparation of bulk samples (such as drug screening, hormone analysis, liquid chromatography, and mass spectrometry in sample preparation) concentration, rotary evaporation instrument to replace the commonly used nitrogen blowing instrument, can also concentrate dozens of samples, time saving and high efficiency.
