Abstract: Devices, systems and methods are disclosed which relate to a prefiltration device that can be used with the concentrating pipette instruments and other devices which draw a sample in through one opening and dispense a concentrated or eluted sample out through the same opening. The device allows the sample to be passed through a prefilter when entering the opening and then bypassed the prefilter when being dispensed through the same opening.
