ABSTRACT:
A biological specimen collection and transport apparatus is provided which is especially useful for collection of sputum. The system includes a hollow specimen collection receptacle which is readily centrifuged. A funnel which has a discharge tube extending into the specimen receptacle is provided for ease of collection of the specimen. The funnel and receptacle are supported by a base. There is also provided an outer protective covering which is flexible and transparent and which coaxially encloses the specimen receptacle and is attached to the funnel. The flexible outer protective covering maintains the exterior of the hollow specimen receptacle free from contamination from the specimen during the specimen collection process. A screw cap is additionally provided and is removably attached to the specimen receptacle for sealing the specimen receptacle.
