Abstract
An air sampler device has a top plate and a bottom plate, and receives a Petri dish between the top plate and the bottom plate. The top plate includes 283 substantially small holes. The bottom plate has a deepened center well formed in the top surface. Elongated slots are formed in the top surface which extend out from the well. The slots have distal ends which extend beyond the Petri dish. Air is drawn into the sampler by a vacuum tube through an air port which communicates with the center well. Air is pulled into the 283 holes in the top plate and strikes the capture material in the Petri dish. The air then travels up over the sides of the dish, into the distal ends, through the slots, and into the center well, where it exits out of the vacuum air port.
