ABSTRACT:
A fluid flow control device useful for liquid chromatography includes a radial distribution plate having a patterned aperture therethrough which pattern is designed to ensure that every annulus of the distribution plate having a given area has the same uniform pressure when fluid flows therethrough. The radial distribution of a fluid throughout the aperture is created by a backpressure means adjacent the downstream surface of the radial distribution plate.
