  • Publication number: 20080290048
    Abstract: A device and method thereof for at least partially fractioning or separating fluid from higher density and/or solid particles contained in liquid samples are disclosed. The present invention provides a movable or drivable device having a flow path defined by inner and outer wall surfaces and arranged such that the flow velocity of the liquid sample along the outer wall surface is higher than the flow velocity along the opposite inner wall surface. The flow path provides elements to at least delay the flow of the liquid sample along the outer wall surface. The device is, e.g., suitable for the separation of blood, e.g., of plasma from at least red blood cells, and from red and white blood cells to achieve blood plasma with high purity for analytical reasons.
