ABSTRACT:
A device for obtaining a relatively particle-free sample of liquid is disclosed. The device comprises a rotatable member having a planar fluid wettable collection surface. The rotating member is disposed within a trough through which a portion of the liquid to be tested passes, thereby resulting in the formation of a thin film of the liquid on the collection surface of the rotating member as it emerges from the liquid. A blade which bears against the collection surface is used to remove the liquid. In accordance with the preferred embodiment, a baffle is provided for deflecting particles floating on the surface of the liquid inside the trough away from the collection surface of the rotating member.
