    Abstract: Filtration device suited for concentration of liquid samples, particularly biomolecules, and a method of concentrating, desalting, purifying and/or fractionating liquid samples. In certain embodiments the device includes a housing having a sample reservoir, and two substantially vertically oriented and spaced apart membranes disposed in the housing. An underdrain is associated with each membrane such that fluid passing through each membrane flows through a respective underdrain into a filtrate collection chamber. The fluid that does not pass through the membrane is collected in the retentate collection chamber, and can be recovered such as by a reverse spinning step, achieving recoveries greater than about 90%. The substantially vertical orientation of the membranes increases the available membrane area by at least 2.7 times the area available in a conventional filter device. The two-panel configuration also maintains more available membrane area in use during the last stages of filtration than a one-panel configuration.

    Abstract: Sample preparation device that allows for a complete bind, wash, elute, buffer-exchange and concentration process to be carried out without sample transfer between multiple devices. The device includes a reservoir, a column for holding chromatography media, a holder region for holding a filtration device, and an outlet. The filtration device plugs into the holder region of the centrifugal device, and the assembly can be placed in an optional holder. The assembly, with or without the optional holder, can be placed in a conventional centrifuge tube for centrifugation. The entire bind, wash, elute, buffer exchange and concentration steps can be carried out with the apparatus without any pipette transfers (and the associated sample losses. The sample preparation device also can be used for binding and washing steps, in which case the filtration device is not needed, and for buffer exchange and concentration steps, in which case the media is not needed.
