Figure 6: Schematic overview of the CULTEX system for exposing cultivated cells to particles at the air-liquid interface. Components of the exposure station: (a) particle generator according to Wright (CULTEX Dust Generator); (b) elutriator: glass tube with vertical upward flow, where large particles are removed from the aerosol due to sedimentation; (c) CULTEX RFS modules for exposure to particles and synthetic air. The sampling points (1–3) for the test aerosols in the overall stream are marked.
