Abstract
A bio-reactive container and filter assembly to improve flow rates and mass transfer without increased pressure. An inlet filter membrane secured to the container defines a container chamber in combination with the container. An inlet filter membrane element may also be secured to the container to provide structural support to the membrane. An outlet membrane secured to the container defines a container chamber in combination with the container. An outlet filter membrane element may also be secured to the container to provide structural support to the outlet membrane. Inlet and/or outlet filters and/or filter elements are constructed to significantly increase surface area available for fluid and/or gas ingress and/or egress. Single and double layer membranes with mixtures of hydrophobic and hydrophilic characteristics are used to maximize perfusion and gasification/degasification of bio-reactive containers.
