  • Patent number: 11067487
    Abstract: This disclosure is directed to an apparatus, system and method for retrieving a target material from a suspension. A system includes a plurality of processing vessels and a collector. The collector funnels portions of the target material from the suspension through a cannula and into the processing vessels. Sequential density fractionation is the division of a sample into fractions or of a fraction of a sample into sub-fractions by a step-wise or sequential process, such that each step or sequence results in the collection or separation of a different fraction or sub-fraction from the preceding and successive steps or sequences. In other words, sequential density fractionation provides individual sub-populations of a population or individual sub-sub-populations of a sub-population of a population through a series of steps.
