A low pressure sample collection apparatus includes a double-ended cap member having similarly sized plug members extending from opposite sides, a vacuum connection nipple on one side and a shaft connection portion one the opposite, a passage extending through the cap from the nipple to the shaft connection portion, a tubular shaft connected to the shaft connection portion and having a sample collection swab member secured to an outer end thereof, and a container member having one end closed and an opposite end open. The cap member is reversibly plugged into the container either to use the container as a handle or to position the swab within the container for protection. A vacuum source may be connected to the assembly to draw air through the swab. The shaft may have a barrel telescoped thereon for separation of the swab from the shaft without contacting the swab. |
