ABSTRACT:
A device for extracting and fragmenting substances, especially infectious or malodorous substances, in a laboratory test vessel (3) is provided. The device includes a processing tool (11) and a stirrer element (33). An interior of the laboratory test vessel (3) is subdivided by a sieve (59) into a collection chamber and a processing chamber. The sieve (59) prevents parts of the substances having a defined rain size from reaching the collection chamber (73). A sample can be taken from the collection chamber using a pipette (45) which is passed through the stirrer element (33) and the sieve (59).
