Abstract:
1. A culture/exposure device for cell and bacteria cultures comprising: a plurality of modules including a base module, a sample receiving module on the base module, an aerosol guide module on the sample receptacle module and a preparation module on the aerosol guide module, wherein each of said plurality of modules are adapted to be selectively connected to one another, detachable from one another and exchangeable with one another; the sample receiving module having a plurality of receptacles, wherein each of said plurality of receptacles is adapted to receive an individual cultural container; the preparation module having an inlet and a flow guide wherein one end of said inlet is connected to a test atmosphere and another end connected to said flow guide which leads gaseous medium from the preparation module to the aerosol guide module; the aerosol guide module having a distribution chamber connected to said flow guide, wherein said distribution chamber has a plurality of flow passages wherein each of the flow passages communicates the test atmosphere to an individual cultural container for charging each cultural container in the plurality of receptacles, the plurality of flow passages are the same length so as to insure that the concentration of particles in the test atmosphere is not altered in a varying manner thus distorting measurement results.
