This product is used to collect all kinds of micro physical evidence on site. When the vacuum cleaner is turned on, the micro-physical evidence enters the collection box from the suction head with the airflow, and the air permeable filter paper is left on the white filter paper. The collection case is transparent, and the tiny physical evidence in the box can be clearly observed. After the collection, you can use tweezers to pick up the small physical evidence in the box and put it into the physical evidence bottle.
