Use: a sampling device for the study of bacterial aerosols and intended for sanitary control of the air environment, is used in veterinary and human medicine. SUMMARY OF THE INVENTION: A device for investigation of bacterial aerosols comprises a housing with the retrieval and the suction nozzles are mounted in the housing scheleobrazuyu- conductive septum mounted in guide plume rectangular substrate feeding device for moving the substrate in the transverse direction, and slits formed in the housing and partitions the grooves to eliminate the erase precipitate aerosol, the substrate is formed as a tray with webs between which is filled with nutrient medium, the width and length of the webs are equal to bs and not the length of the bottom surfaces of the housing walls, contiguous with the substrate, and the height of the webs is 1.3 mm and does not exceed the thickness of the substrate. This device allows to extend the received information about the investigated bacterial aerosol except determining physical parameters of aerosols permits further consider the size distribution and concentration of viable microorganisms and their affiliation to a particular taksinomicheskoy group that is essential during sanitary bacteriological air control in industrial premises livestock and poultry host operatio ns for purposes of ecology and environmental protection from harmful ae ozolnyh emissions. 2 yl., 1 tab.
