ABSTRACT:
An apparatus and method for aerosol testing of experimental animals is provided. In one form, a modular testing chamber includes a fluidized bed generator of aerosol particles as a more reliable method and apparatus for evaluating the effects of environmental aerosols. A particular hexagonal geometry is employed in a tubular testing chamber to provide the most advantageous volume to surface ratios in transporting the aerosols through the chamber. The hexagonal chamber is readily stackable thereby enabling flexibility at the site of the researcher to meet his particular needs.
