Claims

1-30. -30. (canceled)

31. A bioprocessing cartridge comprising:

a) at least one bioprocessing chamber configured to contain a solid support; and

b) a plurality of mesoscale and/or microscale process fluid channels in fluid communication with the bioprocessing chamber through at least one pump, wherein the at least one pump is included in or on the bioprocessing cartridge.

32. The cartridge of claim 31 wherein said cartridge comprises at least one access valve within a flow path defined by at least one of the plurality of process fluid channels.

33. The cartridge of claim 32, wherein each of said at least one access valves is located within a flow path between a process fluid connector and the at least one of the plurality of process fluid channels, each process fluid connector configured to fluidly connect the cartridge to one or more fluid containers.

34. The cartridge of claim 33, wherein said cartridge comprises more than one access valve, wherein each access valve is placed within a flow path between an independent process fluid connector and one of the plurality of process fluid channels, each independent process fluid connector configured to fluidly connect the cartridge to one or more fluid containers.

35. The cartridge of claim 33, wherein said process fluid connectors are configured to connect to said fluid containers via a manifold.
