Abstract: A fecal parasite concentrator which has a cylindrical body (20) with connections for a sample vial (24) on one end and a centrifuge tube (28) on the other. An integral filter (36) is disposed within the body at right angles coaxially covering the cross sectional area of the hollow body. The filter contains a series of closely spaced square openings for filtration of a liquid diluted fecal specimen. A hollow stem (40) with truncated end (44) extends upwardly from the filter and a number of geometrically shaped orifices (46) permit air to pass therethrough when the diluant specimen flows through the filter.
