Described herein are methods, systems, and apparatus for separating components of a sample; as well as methods of using compositions prepared by same. In one aspect, the apparatus can comprise a tubular body for receiving sample, a thixotropic material, and a float. The system comprising the apparatus can be configured to separate the component of the sample using centrifugation. The float can have a specific gravity less than or equal to the specific gravity of the thixotropic material. The thixotropic material can be positioned along a bottom inner surface of the tubular body, and a portion of the float can be embedded in the thixotropic material. The float can be made of a single, integral piece or a plurality of pieces that are configured to be fixed and immobile relative to each other during centrifugation. The float can be solid, nonporous and without any aperture.
