The ends of bundles of microporous tubing may be potted in otherwise conventional manner for assembly as a diffusion device for oxygenation of blood, blood plasmapheresis, or the like. In accordance with this invention, prior to impregnating the bundle ends in sealant, the micropores of the capillary tubing are filled with a liquid capable of entering the micropores, with the result that air in the bores of the tubing cannot migrate outwardly through the micropores as the sealant impregnates the bundle ends. This, in turn, prevents the sealant from advancing into the bores of the tubing to the level occupied by the sealant outside of the bores of the tubing, so that the ends of the potted bundle may be transversely cut within the block of cured sealant to expose open bores of the tubing.

The method of potting the ends of capillary tubing having microporous walls, which comprises impregnating the ends of said tubing with a curable, fluid sealant, curing said sealant, and thereafter transversely cutting through the sealant-impregnated ends of said tubing to expose an open bore of said tubing surrounded on its exterior by cured sealant, the improvement comprising, in combination: prior to impregnating said tubing ends in sealant, filling the micropores in the walls of said tubing with a liquid capable of entering said micropores, whereby air in the bore of said tubing cannot migrate outwardly through said micropores in the walls as the sealant impregnates the tubing ends.
