<p>A filter wetting or flushing apparatus (10) according to one aspect of the invention comprises a syringe (11) having a cylinder (13) and a piston (14), a liquid inlet (15) and a liquid outlet (16), and a valve assembly (20, 21). The liquid inlet and the liquid outlet are in fluid communication with the barrel space (17) of the cylinder. The valve assembly allows liquid flow from the liquid inlet to the cylinder but blocks reverse liquid flow, and allows liquid flow from the cylinder to the liquid outlet but blocks reverse liquid flow. The liquid inlet is adapted to be connectable to a port (2) of a filter (1) to draw a liquid (3) through the filter into the suction port. An apparatus (80) for wetting or flushing a filter (85) according to another aspect of the invention comprises a pump (81) that includes a suction port (82) and a pressure port (83). The suction port is adapted to be connectable to a port (84) of a filter (85) to draw a liquid (86) through the filter into the suction port.</p> |
