Abstract
A method for making a hollow fiber separation device including the steps of forming an integral structure which comprises at least one tubular housing portion and an elongated chamber portion extending in elongated relation to the tubular housing portion and communicating with the housing portion adjacent opposed ends thereof. One provides an aperture in a central area of the elongated chamber and inserts hollow fibers for diffusion into the housing portion. One then provides closed ends to the housing portion and spins the structure on an axis between the ends, adding potting compound to the chamber portion through the aperture. Accordingly, the potting compound migrates radially outwardly through the chamber to the closed ends of the housing portion, to encase the ends of the hollow fibers in the potting compound. After curing of the potting compound, the ends of the tubular housing portion may be transversely cut to expose open bores of the hollow fibers, and flow manifold end cap members applied to the cut tubular housing ends.
