1. A method of separating a component of a multiple component material, comprising:

  • separating, within a container system, at least a portion of a solid portion from a liquid portion of a multicomponent material at least by retaining the portion of the solid portion of the multiple component material in a first section of the container system with a filtration system having a first filter media portion positioned between the first section and a second section of the container system, wherein a buoy is slidably received within the second section, the buoy having a first buoy member and a second buoy member;

    forming at least a first fraction and a second fraction of the liquid portion after the liquid portion has moved from the first section to the second section, wherein the buoy moves within the second section to isolate the first fraction at least from the second fraction;

    removing the first section from the second section following fractionation such that the first filter media portion is removed from the second section, wherein the first filter media portion retains the portion of the solid portion of the multiple component material in the first section during fractionation; and

    extracting the first fraction from the second section.
