Abstract:

A specimen container of generally tubular construction and formed with a base tube defining a specimenreceiving chamber for receipt of a fecal specimen or the like and which is flared outwardly at its upper extremity for receipt of the open lower end of a tubular top member formed in its lower extremity with inwardly flared walls for frictionally engaging the outward flare of the base tube. The top member is formed interiorally with a conical wall which is open in its upper extremity to define an access orifice for analysis of a specimen contained therein. A cap is provided for covering the top member whereby a specimen may be placed in the base tube and the top member mounted on such base with the cap in position overlying the access orifice. The container may then have a fluid added thereto and the entire container then spun in a centrifuge with the base disposed radially outwardly in such centrifuge to cause the high density material in such specimen to seek the bottom of such base and the low density material, such as parasite eggs, to be forced upwardly in the container to be disposed in such orifice for easy access thereto when the cap is removed.
