A singulation assembly for a solid wall isolation, incubation and normalization (SWIIN) module comprising:
- a retentate member comprising;
- an upper surface and a lower surface and a first and second end,
- an upper portion of a serpentine channel defined by raised areas on the lower surface of the retentate member, wherein the upper portion of the serpentine channel traverses the lower surface of the retentate member for about 50% to about 90% of a length and width of the lower surface of the retentate member;
- and
- at least one retentate port fluidically connected to the serpentine channel;
- and
- a permeate member disposed under the retentate member comprising:
- an upper surface and a lower surface and a first and second end,
- a lower portion of the serpentine channel defined by raised areas on the upper surface of the permeate member, wherein the lower portion of the serpentine channel traverses the upper surface of the permeate member for about 50% to about 90% of a length and width of the upper surface of the permeate member, and wherein the lower portion of the serpentine channel is configured to mate with the upper portion of the serpentine channel to form the serpentine channel;
- and
- at least one permeate port fluidically connected to the serpentine channel;
- and
- a first gasket disposed under and adjacent to the retentate member and above and adjacent to the permeate member.

- a first gasket disposed under and adjacent to the retentate member and above and adjacent to the permeate member;
- first and second reservoirs at the first end of the permeate member, wherein the first reservoir is fluidically connected to the at least one permeate port in the permeate member and the second reservoir is fluidically connected to the at least one retentate port in the retentate member;
- a reservoir cover at the first end of the retentate member;
- and
- a second gasket disposed on top of the reservoir cover, wherein the second gasket comprises for each of the first and second reservoir a reservoir access aperture configured to provide fluid access to a reservoir and a pneumatic access aperture configured to provide pneumatic access to a reservoir.
