A PREPRIMED FILTER DEVICE AND ITS METHOD OF MANUFACTURE

摘要

A filter device (10) has a porous material (17) which has been wetted without the use of any substance which would spontaneously wet the material. In one embodiment, the device includes a hydrophobic filter material (27) which has been wetted solely by subjecting the material to a pressurized stream of an aqueous solution (26). The solution (26) can remain associated with the filter material (27), resulting in a prewetted and preprimed device (10).
