A device comprising:
- a sintered porous polymeric medium;
- a solution-coated phase inversion porous membrane;
- a housing with a single lumen defined by an inner wall and an outer wall, an open first end and an open second distal end;
- wherein the sintered porous polymeric medium is located at the open second distal end of the single lumen of the housing and the solution-coated phase inversion porous membrane at least partially covers the sintered porous polymeric medium and a portion of the adjacent outer wall of the housing, forming a seal over the open second distal end.
