Abstract

A novel method of fabricating capillary hollow fibre bundles on a labor atory scale is described. This technique involves the use of the membrane support plate of a Kiil flat-plate dialyser. The fibres can be placed, either individually or collectively, in the V-grooves of the support plate, and then encapsulated using a silicone rubber elastomer to yield fibre tube sheets. These tube sheets are wound up together to form fibre bundles, and then encased in a Perspex shell to yield a capillary fibre mass-exchanger. Our results indicate that this convoluted tube sheet technique can be employed to characterise membrane permeability and permits reproducible results to be obtained.
