16 . The cap of claim 1 , wherein the fluid transfer device comprises a plastic pipette tip.

17 . The cap of claim 16 , wherein the pipette tip has a generally conical portion.

18 . A collection device comprising the cap of claim 1 in fixed association with a fluid-holding vessel.

19 . The collection device of claim 18 , wherein the vessel contains a biological specimen.

20 . The collection device of claim 19 , wherein the collection device contains a specimen retrieval device spaced-apart from the axis of the collection device.

21 . The collection device of claim 19 , wherein the collection device further contains a lubricant.

22 . The collection device of claim 21 , wherein the lubricant is a detergent.
