Abstract
The present disclosure provides a cell harvesting method and device for the efficient sedimentation and retention of cells from liquid samples onto a solid support with low cell losses and low impact on cell morphology. The device has two configurations, one being for use in a centrifuge to centrifuge the sample, a second for controlled release of the liquid post centrifugation. The device includes a base to hold a solid support that receives cells on a top surface thereof that releasably holds a fluid chamber which has a first opening with a gasket surrounding the opening with that bears against a top surface of the support. An opening receives the liquid sample and the gasket defines an area into which the targeted cells deposit. A first cap closes the second opening during centrifugation. Post centrifugation the first cap is removed and a fluid absorbing element and cap, designed to provide controlled removal of the liquid and to prevent positioning of a tip of the absorbing element to a distance from the solid support shorter than a predefined distance is inserted into the fluid chamber.
