ABSTRACT:
The unitary device includes a generally tubular container having a generally central specimen collection space communicating with the open upper end of the container, and a microscope slide member below and integral with the container and having transparent flat front and rear walls throughout at least a portion thereof, and a central cavity therebetween communicating with the container space through the lower end of the container. The container is adapted to serve as a centrifugation tube and a permanent handle for manipulation of the microscope slide member. The back of the device is generally flat and the front and sides of the collection tube are generally rounded. In one embodiment, the device is of thermoformed plastic and may include a flexible front wall in the microscope slide member, overlaid by a removable flexible support strip attached thereto by spaced ribs of adhesive so that such front wall ripples and flexes during removal of the strip to uniformly mix sediment collected in the cavity. The depth of the microscope slide member may be decreased by a stepped portion in the back thereof.
