The fluid handling apparatus (100) has a displaceable piston (116) that is arranged with a piston stopper (118,120) in a receptacle. A fluid receiving reservoir (160) is formed between the piston stopper, receptacle wall and a receptacle bottom, in which a fluid opening (114) is formed. A sealing device (152) is attached to the receptacle and the piston, where the piston is surrounded by the sealing device. The piston plug of the piston is displaced in a portion (153) of the receptacle adjacent to a portion of the receptacle wall, in which a filter (158) is installed through an opening (156).
