This disclosure is directed to tube and float systems that can be used to detect target materials in a variety of different suspensions. The tube is filled with a suspension suspected of containing a target material. When the tube, a float, and suspension are centrifuged, and the various materials suspended in the suspension are separated into different material layers along the axial length of the tube according to associated specific gravities. The float includes an insert and a float exterior that can be combined so that the float is to be positions at approximately the same level as the layer containing the target material. The float is to be positioned in, and expand the axial length of, the target material layer so that nearly the entire quantity of target material is to be positioned between the float outer surface and the inner surface of the tube.
