A filter assembly for separating microcarriers from a fluid medium includes a collapsible container bounding a sterile compartment adapted to hold a fluid. An inlet port is attached to the container through which fluid flows into the compartment. An outlet port is attached to the container through which fluid flows out of the compartment. A filter is disposed within the compartment, the filter dividing the compartment into an inlet chamber that is fluidly coupled with the inlet port and an outlet chamber that is fluidly coupled with the outlet port, the filter allowing a medium to pass therethrough but preventing microcarriers disposed in the medium from passing therethrough.

1. A filter system for separating microcarriers from a fluid medium, the filter system comprising: a substantially rigid support housing having a floor with a side wall upstanding therefrom, the floor and the side wall bounding a chamber; anda filter assembly being removably disposable within the chamber of the support housing, the filter assembly comprising: a container bounding a sterile compartment adapted to hold a fluid;an inlet port through which fluid flows into the compartment, the inlet port being removably attachable to the support housing;an outlet port through which fluid flows out of the compartment; anda filter disposed within the compartment, the filter dividing the compartment into an inlet chamber that is fluidly coupled with the inlet port and an outlet chamber that is fluidly coupled with the outlet port, the filter allowing a medium to pass therethrough but preventing microcarriers disposed in the medium from passing therethrough, the filter comprising a porous bag or sock that bounds the inlet chamber, the porous bag or sock being coupled with the inlet port either directly or through a tube. 2. The filter system as recited in claim 1, wherein the container comprises a flexible bag. 3. The filter system as recited in claim 1, wherein the porous bag or sock is coupled with the inlet port by the tube. 4. The filter system as recited in claim 1, wherein the filter is expandable. 5. The filter system as recited in claim 1, wherein the filter is flexible. 6. The filter system as recited in claim 1, wherein the filter is comprised of a mesh material or a perforated polymeric sheet. 7. The filter system as recited in claim 1, wherein the filter is coupled with the inlet port so that any fluid medium passing through the inlet port passes through the filter. 8. The filter system as recited in claim 1, wherein the filter comprises: a plurality of sheets, at least one of the sheets being comprised of a porous material, the plurality of sheets being bounded together at their peripheries to form the inlet chamber; anda filter inlet port through which fluid flows into the inlet chamber, the filter inlet port extending through at least one of the plurality of sheets, the filter inlet port being fluidly coupled with the inlet port. 9. The filter system as recited in claim 1, wherein the container has a floor and the filter is suspended above the floor. 10. The filter system as recited in claim 1, wherein the container is removably attachable to an upper end of the support housing. 11. A filter system for separating microcarriers from a medium in which the microcarriers have been added to aid in cell culture development, the filter system comprising: a support housing having a floor with a side wall upstanding therefrom, the floor and the side wall bounding a chamber; anda filter assembly being removably disposable within the chamber of the support housing, the filter assembly comprising: a container bounding a sterile compartment adapted to hold a fluid;a filter port attached to the container, the filter port having a fluid passageway extending therethrough such that a cultured solution having microcarriers therein can pass therethrough; anda filter disposed within the sterile compartment and coupled to the filter port so as to fluidly communicate with the fluid passageway of the filter port, the filter comprising a porous bag or sock that bounds an inlet chamber and is being comprised of a porous material configured to allow a cultured solution that includes cells to pass therethrough while preventing microcarriers from passing therethrough; andan inlet port attached to the porous bag or sock, the inlet port being fluid coupled with the filter port and being removably attached to the support housing. 12. The filter system as recited in claim 11, further comprising an outlet port attached to the container, the outlet port having a fluid passageway extending therethrough such that the cultured solution can exit the sterile compartment therethrough. 13. The filter system as recited in claim 11, wherein the filter comprises: a plurality of sheets, at least one of the sheets being comprised of a porous material, the plurality of sheets being bounded together at their peripheries to form the inlet chamber; anda filter inlet port through which fluid flows into the inlet chamber, the filter inlet port extending through at least one of the plurality of sheets, the filter inlet port being fluidly coupled with the filter port. 14. The filter system as recited in claim 13, wherein the filter inlet port is fluidly coupled with the filter port by a tube. 15. The filter system as recited in claim 13, wherein the plurality of sheets comprises a first sheet and a second sheet bounded together at their peripheries, the second sheet being comprised of the porous material, the first and second sheets bounding the inlet chamber. 16. The filter system as recited in claim 15, wherein the plurality of sheets further comprises a third sheet having an opening extending therethrough, the third sheet being bounded to the first and second sheets at the periphery of the third sheet such that the second sheet is sandwiched between the first and third sheets at the periphery of the second sheet. 17. The filter system as recited in claim 15, wherein the first sheet has an opening extending therethrough, and the plurality of sheets further comprises a third sheet, the third sheet being comprised of the porous material, the third sheet being bounded to the first sheet to cover the opening therein, the third sheet also bounding the inlet chamber. 18. The filter system as recited in claim 15, wherein the perimeter edges of the first sheet are wrapped around the perimeter edges of the second sheet and bounded thereto. 19. A filter system for separating microcarriers from a medium in which the microcarriers have been added to aid in cell culture development, the filter system comprising: a support housing having a floor with a side wall upstanding therefrom, the floor and the side wall bounding a chamber; anda filter assembly being removably disposable within the chamber of the support housing, the filter assembly comprising: a flexible bag bounding a sterile compartment adapted to hold a fluid;a filter comprising a porous bag or sock comprised of a porous sheet of flexible material, the porous bag or sock bounding an inlet chamber;an inlet port coupled with the flexible bag and being removably attached to the support housing;a tube extending from the inlet port to the porous bag or sock so as to communicate with the inlet chamber; andan outlet port coupled with the flexible bag so as to communicate with the sterile compartment. 20. The filter system as recited in claim 11, further comprising a tube extending from the filter port to the inlet port.
