Abstract
A device for collecting cellular material from a fluid sample comprises first and second chambers that are releasably connected and which define a fluid flow path from the first chamber to the second chamber. A porous membrane is between the chambers when they are connected to each other, in the fluid flow path. An absorbent body is positioned in close proximity to the downstream surface of the porous membrane, and a resilient member is arranged to urge the absorbent body towards the porous membrane. In use, a sample introduced into the first chamber contacts the upstream surface of the porous membrane and fluid is drawn through the porous membrane and is absorbed by the absorbent body. Cellular material is retained upon the upstream surface of the porous membrane. After separation of the chambers, the porous membrane can be removed from the device for analysis of the deposited cellular material.
