ABSTRACT:
The invention provides a specimen collection and sampling device, particularly useful for urine samples, for collecting a liquid sample and segregating an aliquot of the sample away from contact with the remaining portion of the sample. This segregation is accomplished as the lid is closed on the container. In one embodiment, the aliquot sample is transferred to an evacuated tube held within the container. In another embodiment, the aliquot is held within a sample chamber that is built into the container. In a preferred embodiment, the aliquot is mixed with a treating agent to maintain the microbiological integrity of the aliquot, or to provide an appropriate reagent or buffer for drug analysis.
