ABSTRACT A method of assembling a hollow fibre mass transfer device by centrifugally potting both ends of a bundle of open-ended hollow fibres in a casing, wherein the casing is fitted with at least one such bundle of open-ended fibres, each fibre of which has each end projecting at least approximately 5 millimeters beyond the desired outer face of the potted assembly in the device, and wherein the method comprises the steps of mounting the casing with the projecting fibres in a centrifugal potting apparatus for simultaneous centrifugation of both ends of the fibre-carrying cas?ng, centrifuging the mounted fibre- carrying casing and delivering a liquid settable potting composition substantially simultaneously to both ends of the centrifuging casing to cause that composition to enter the casing ends and the fibre ends but to move into the fibre ends a distance less than the length of said projecting end and after the potting composition is set cutting off the projecting masses of fibre ends to provide the desired outer faces having cut fibre potted in the casing ends with the cut ends of the fibres open.
