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.
A device and method for the concentration of parasite eggs and larvae consisting of separable upper and lower chambers connected by a mid-piece which incorporates a filter of stainless steel gauze. The sample is emulsified in the upper chamber and is filtered into the lower chamber. Ether is added through the upper chamber and the mid-piece and upper chamber are removed. The lower chamber is shaken and centrifuged, the mid-plug of debris is removed, and the tube is drained and swabbed clean leaving a small sediment containing the parasite eggs and larvae. The sediment is removed by extraction with Lugol's iodine or saline to dilute the sediment.
A container for holding a small quantity of liquid. The container comprises an elongated housing having a fluid receptacle disposed in the upper end thereof. The dimensions of the receptacle are substantially less than the overall dimensions of the housing, thereby facilitating the handling of the container and inhibiting evaporation of the liquid therein.
The invention provides a biological sampling and storage container which is easy and sanitary to use, may be shipped through regular mail, and includes a drying material or desiccant for drying feces samples that are stored therein. The sampling and storage container consists of a body having a sampling chamber and a drying chamber which are in gaseous communication with each other. Preferably, a sampling wand is frictionally retained in the sampling chamber and the drying material is disposed in the drying chamber.
