Beschreibung
Zusammenfassung:	A concentration device that concentrates a solution containing a biological substance includes: a first chamber into which the solution is to be introduced; a second chamber to be filled with a drawing agent; and a film that separates a space of the first chamber and a space of the second chamber. The film has a first region and a second region. The first region is semipermeable in that the first region is permeable to a solvent of the solution but impermeable to the biological substance and the drawing agent. The second region is impermeable to the solution, the biological substance, and the drawing agent. When the solution is introduced into the first chamber, the film is positioned to incline with respect to a surface of the solution. The second region is positioned below the first region with respect to the surface of the solution.
