background   Â
For many chemical laboratories, there are more or less traces of chemical leakage and poor ventilation. This directly leads to high laboratory odor and high VOC concentration, which can be equipped at indoor volatile sources. The movable universal exhaust hood will greatly improve the indoor environment, restore clean air in the laboratory, and protect the physical and mental safety of chemical laboratory workers.

Principle and schematic
The inside of the cabinet is equipped with a fan and a filter. The fan draws the wind at the volatilization source into the filter device of the tank through the suction hood and the pipeline, and the clean air after the filtration is directly discharged into the room.
Application range
All volatile sources with local volatility, such as chemical operation, volatilization during the working process of the instrument, soldering, etc.
Dissolution, mixing, stirring, pipetting, sampling, pH testing, Kjeldahl, HPLC, GC-MS, LC-MS...
The filter has strong adsorption capacity for organic solvents, acids, bases, perfumes, pesticides and the like.

Antigen Extraction Tube
Antigen extraction cells refer to a class of cells that can take up, process antigens and present antigen information to T lymphocytes, also known as helper cells. In the process of thymus-dependent antigen inducing B lymphocytes to produce antibodies, not only the synergistic effect of T and B lymphocytes is required, but also the assistance of another type of cells, so this type of cells is called helper cells. It plays an important role in the body's immune recognition, immune response and immune regulation.
