ABSTRACT:
A method for removing liquid from a gel matrix including the steps of providing a hydrophobic water vapor-permeable membrane adapted to transmit water vapor and to resist passage of liquid water by capillary diffusion. The membrane and gel matrix are contacted together and subjected to a vacuum to remove water vapor from the gel matrix through the membrane. Liquid is removed from the gel matrix, and the gel matrix simultaneously adheres to the membrane.
