Safety evaluation of cell exposure in vitro

In view of the EU and the United States' advocacy of the 3R principles of experimental animals and the upsurge of alternative methods for animal experiments, Hui Ronghe technology in Beijing has developed an in vitro cell aerosol exposure system, which can be used to carry out in vitro fine cell exposure test of gas, volatile substances, liquid aerosols and dust aerosols. A unique air - liquid exposure technique was used to simulate the human lung environment, to realize the cell dynamics in vitro, to expose the aerosol exposure, and to complete the study on the exposure safety of the subjects at the cell level in vitro.
