The present disclosure is directed to a method and apparatus for removing a small sized sample from a very large tanker container. The tank is closed, a valve is mounted in the deck which closes the tank, and the present apparatus attaches to that valve. This defines an open and close passage into the tank. A sample container on a measured steel tape is lowered through the passage into the tank and retrieves a measured sample. Sample container is removed outside the tank in a sample transfer mechanism. The sample transfer mechanism incorporates a container filling head or assembly which features a pair of needles which penetrate the septum on the mouth of a half liter or liter container which can be carried to a test facility after filling. Two needles are used, one to introduce the liquid into the container and the other to vent the container fumes or any over flow, and the vented fumes and over flow are directed to a charcoal carbon filled filter.
