Sample preparation device for receiving in sealing relation one or more filter assemblies and one or more sample containers, each container uniquely positioned within the device to receive filtered sample from a designated filter. The device includes a body, a lid disposed on the body, a container tray, a base, an integrated seal on the body, a valve and a valve actuator. The tray can be disposed in a vacuum chamber defined by the lid and the body, and one or more sample containers can be disposed in the tray. When properly positioned in the tray in the vacuum chamber, each container is in fluid communication with a single respective filter assembly disposed in sealing relation in a respective aperture in the lid. A single actuation of a valve to place the vacuum chamber under vacuum causes the lid to seal to the base and drives the simultaneous filtration of a plurality of samples.
A filter, comprising a sample reservoir defined by a fluid impervious wall, a membrane, a membrane support supporting said membrane and comprising concentric circumferential slits and a plurality of spokes which traverse said concentric circumferential slits, and an axially disposed elongated member in fluid communication with said sample reservoir through said membrane, said elongated member having a fluid outlet.
A plurality of interconnected filters, each filter comprising a sample reservoir defined by a fluid impervious wall, a membrane, a membrane support supporting said membrane and comprising concentric circumferential slits and a plurality of spokes which traverse said concentric circumferential slits, and an axially disposed elongated member in fluid communication with said sample reservoir through said membrane, said elongated member having a fluid outlet;
