Cell recovery method and device

A cell recovery device for sedimentation and retention of target cells from a fluid sample onto a solid support by centrifugation, comprising:

• a base configured to releasably hold the solid support, the solid support having a surface to receive the target cells;
• a fluid chamber having a first opening arranged to be sealed against the solid support when the solid support is held by the base, and a second opening opposite to the first opening for receiving the fluid sample, and
• a separate fluid absorbing element positionable within the fluid chamber post-centrifugation for removal of fluid from the fluid chamber, the fluid absorbing element providing a controlled flow rate of the fluid being absorbed by the fluid absorbing element such that the sedimented cells are not detached from the surface of the solid support.

A fluid absorbing element of a cell recovery device for sedimentation and retention of target cells from a fluid sample onto a solid support by centrifugation, the absorbing element comprising:

• a body of porous material having a tip, and
• an enclosure surrounding the body of porous material, the enclosure having an opening at the tip of the body of porous material through which fluid can enter the body of porous material,
• wherein the fluid absorbing element is mountable inside a fluid chamber of the cell recovery device post centrifugation such that the tip of the body of porous material is spaced from a surface of the solid support by a predetermined distance and fluid is absorbed by the fluid absorbing element at a controlled rate such that the sedimented cells are not detached from the surface of the solid support.
