Sampling cup for microbiological suspension particles in an atmosphere and sampling device for said cup

摘要

A sampling cup for microbiological suspension particles in an atmosphere and portable sampling device provided with one such cup. The sampling cup for microbiological particles in a suspension in an atmosphere comprises a rotary cup body provided with a bottom ( 30 ) and a peripheral wall ( 32 ) which is generally cylindrical, extending from said bottom and defining with said bottom a volume filled with a trapping medium for the suspension particles. The body of the cup also comprises a crown ( 34 ) partially closing the outer section of the peripheral wall of the body and defining a passage ( 36 ) for the particles. The crown is provided with channels ( 38 ) extending in an externally outer radial manner in the direction of the periphery of the body and adapted in such a way that it produces an air flow towards the receiving medium filling the body via said passage when the body is rotated in a housing.
