Systems for analyzing target materials of a suspension include a tube and a float in which at least a portion of the float is porous. The at least one pore can allow for the flow of fluids and reagents out of the float and into a space between the outer surface of the float and the inner surface of the tube. The at least one pore can also prevent unwanted particles or material from flowing into the float. The introduction of additional fluids, such as fixing agents, washing agents, detergents, or labeling agents, may aid in further processing or detection of the target analyte. The porosity of the float may also allow for the target analyte to be extracted through the float by introducing a removal device, such as a vacuum, to draw the target analyte through the float and into the vacuum. |
