The Nitrogen purging instrument is a high-precision temperature control instrument. Its working principle is to blow nitrogen quickly, continuously and controllably onto the surface of the heated sample. According to the evaporation speed and boiling point of the concentrated solvent, the heating temperature is set to achieve a large number of Quick concentration 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.
● Each purge needle can be controlled independently, with 12 airway control switches, no gas wasted.
● The heater enables the sample to be quickly and effectively heated to the evaporation temperature, and at the same time the gas is blown from the gas chamber to the surface of the solution through the gas needle, which promotes the rapid evaporation of the solution and the concentration of the sample.
● The whole working system is composed of adjustable gas chamber and heater.
● The position of the air needle in the air cavity can be changed to make it suitable for different positions. The standard air needle length is 150mm.
● The height of the air chamber can be adjusted according to the height of the liquid level of the solvent. When concentrating toxic solvents, the entire system can be placed in a fume hood.
● Automatic fault detection and alarm function, standard equipped with air cavity and special adjustable bracket.
