Let's take a look at the water bath nitrogen blowing instrument

The water bath nitrogen blowing instrument adopts the combination of microcomputer control technology and PID control mode to form a high-precision control instrument, and its working principle is to quickly, continuously and controllably blow nitrogen to the surface of the heated sample, and set the heating temperature according to the evaporation speed and boiling point of the concentrated solvent to achieve rapid anaerobic concentration of a large number of samples
.

Water bath nitrogen blowers include base and bracket units, sample holders, and gas distribution systems
.

The test tube is fixed by means of a spring-loaded test tube clamp and a support disc
.

Each sample bit has a numeric number; The gas passes through the flow meter to the gas distribution system, and the flexible guide tube directs the gas into valves and stainless steel needles at each location, blowing the gas to the sample surface, allowing the solvent to evaporate
quickly.

Depending on the size of the tube and the amount of solvent, each gas duct can be raised and lowered to the appropriate height
.

Before the nitrogen blower is used, carefully check the contents of the box to confirm whether the contents of the box are consistent with the packing list and confirm whether the transportation process is damaged.

Keep the boxes and packaging materials until all parts and instrument installation tests have been inspected
.

Fully automatic control of the dual gas path configuration, can be connected to the nitrogen source and air source at the same time, you can also choose one of them, the air path automatically opens when the boot purges, and the gas circuit automatically closes when the purging is completed, saving the consumption of gas; When the nitrogen blower air source is selected as the gas source, the control system can automatically control the switch of the nitrogen blower air source, eliminating the need for cumbersome manual operation
