Abstract: A wash system for cleaning the exposed surfaces of a contaminant collection device that includes a source of pressurized cleaning solution and a rinse appliance. The rinse appliance includes a first flow path that is adapted to direct the pressurized cleaning solution against a plurality of interior surfaces of a sampling head of the contaminant collection device and a vacuum tube that couples the sampling head to a collection chamber of the contaminant collection device. The rinse appliance may also include a second flow path that is adapted to direct the pressurized cleaning solution against a plurality of interior surfaces of the collection chamber and a separator filter installed therein. The rinse appliance further includes a dipping tank adapted to receive the cleaning solution after passing through one of the first and second flow paths.

Abstract: A system is disclosed for sampling contaminants from a soft test surface that includes a vacuum sampling device. The vacuum sampling device includes a spray port that is in fluid communication with source of sterilized sampling fluid, and which delivers a quantity of sampling fluid onto the soft test surface, a suction head having an outer casing surrounding an open-faced suction cavity that is in communication with a vacuum source and which retrieves the sampling fluid from the test surface, and a storage container for holding the retrieved sampling fluid. The system further includes a retention screen positioned between the test surface and the suction head, and which prevents the soft test surface from substantially occluding suction and reducing mobility of the suction head when engaging the soft test surface.
