  • Methods for filtering fluids
    Patent number: 7166225
    Abstract: A fluid filtering device includes a plurality of filtering wells and an angling mechanism which adjusts the angle of the membranes within the filtering wells relative to a line of a centrifuge where the line is perpendicular to the axis of rotation of a centrifuge and passes through the center of a major plane of the filtering device. The angling mechanism can include a wedge located between the center of rotation of a centrifuge and a swinging bucket of the centrifuge. The angling mechanism can also be located within each filtering well and can provide individually specified angles for each membrane, relative to the line of the centrifuge.
    Type: Grant

  • Method of forming well(s) containing filtration devices
    Patent number: 6764653
    Abstract: A single or multiwell plate using membrane, preferably an ultrafiltration membrane to filter selected solutes from a liquid is disclosed. In particular, a preferred construction and method of sealing the membrane to the interior of the well so as to form an integral seal between the top portion of the well and the bottom portion is disclosed. The preferred method is to use a heat seal device which secures the filter to the underdrain portion of the device.
