ABSTRACT:
A sample injection device is provided, comprising a vented needle having a body, the body having an upper end and a lower end, a point on the lower end, an injection passageway running axially through the body and communicating between the upper end and the lower end, and a vent passageway, running through the body and communicating between the lower end and the exterior of the body. The upper end of the body is connectable to a valve, and the lower end is connectable to a receptacle for receiving samples. When equipped with a circulating system and combined with a wheeled transport tank such as a railroad tank car or highway tank trailer having a reservoir, or a marine transport tank such as a barge, the invention enables the user to accomplish representative emission-free sampling of such transport containers and comprises a suction line extending into the reservoir; a pump having a suction port and a discharge port, the suction port being connected to the suction line; a discharge line connected to the discharge port; a sampling unit, for removing a sample from the discharge line, connected to the discharge line; a return line, connected on one end to the discharge line terminating within the reservoir.
