<p>A device (10) for reducing the amount of particulate contaminant in a liquid is provided which includes a hollow elongate member (12) having first and second openings (14,16) and filter means (18), preferably depth filter means, positioned in the elongate member, the filter means in combination with the elongate member defining a reservoir (24) between the filter means and the first opening. The device is intended to be used with means (26) associated with the first opening for generating a pressure differential between the interior of the elongate member and the exterior thereof whereby a liquid containing particulate contaminant may be introduced into the reservoir (24) in the elongate member through the second opening, particulate contaminant being trapped within the filter means and a liquid with a reduced particulate contaminant may be removed from the elongate member through the second opening.</p> |
