The vial is particularly designed to retrieve urine specimens from a jar or other container provided by a patient. The vial itself is in the form of a bellows biased to its expanded position. A straw is provided axially in the bellows such that the bellows can be manually collapsed and then released so that the specimen is sucked up through the straw into the bellows. The bellows itself has a bottom shaped to be received in a centrifuge and is also provided with a cap which replaces the straw prior to centrifuging. The cap itself can be removed after centrifuging and defines a fixed volume for collecting a given amount of sediment and liquid for ultimate analysis on a slide. The straw serves the dual function of axially supporting the bellows arrangement during collapsing by guiding the bellows walls and also as a conduit or passage for transferring urine into the bellows.
