<p>A fluid sampling tool for sampling fluid from a container. The tool has a fluid collecting portion (2) which is drilled into the container wall, thereby affixing it to the wall. The tool may have a fluid extracting section (82) which withdraws fluid collected by the fluid collecting section (2). The fluid collecting section has a fluted shank (46) with an end (54) configured to drill a hole into a container wall. The shank (46) is threadably engaged to a cylindrical housing (4) having an inner axial passageway (12) sealed at one end (8) by a septum (22). A flexible member (56) having a cylindrical portion (60) and a bulbous portion (62) is provided. The housing (4) can be slid into an inner axial passageway (68) in the cylindrical portion (60) and sealed to the flexible member. The bulbous portion has an outer lip (74) defining an opening. The housing (4) is clamped into the chuck of a drill, the lip (74) of the bulbous portion (62) is pressed against a container wall until the shank (46) touches the wall, and the user operates the drill. Wall shavings (kerf) are confined in a chamber (78) formed in the bulbous section (62) as it folds when the shank (46) advances inside the container. After sufficient advancement of the shank, an o-ring (38) makes a seal with the container wall.</p> |
