This disclosure is directed to an apparatus, system and method for retrieving target material from a suspension. A system includes a processing vessel, a displacement fluid, and a tube. The tube includes a funnel, a cannula, and a cavity. The cannula allows for fluid communication between the funnel and the cavity, such that the processing vessel is inserted into the cavity, and the cannula extends into the processing vessel. 1. A system comprising: a first end,', 'a second end comprising an aperture,', 'a biological suspension comprising a target material, and', a funnel comprising a mouth proximal to the first end and an apex distal to the first end,', 'a cavity extending from the aperture in the second end towards the apex of the funnel, and', 'a cannula extending from the apex of the funnel into the cavity; and, 'a collection segment between the first and second ends, the collection segment comprising'}], 'a tube comprising'}a processing vessel comprising a closed end and a displacement fluid having a density greater than a density of the target material,wherein at least a portion of the processing vessel is located within the cavity of the tube, andwherein the cannula extends through the closed end of the processing vessel.2. The system of claim 1 , wherein the displacement fluid is selected from the group consisting of: a solution of colloidal silica particles coated with polyvinylpyrrolidone claim 1 , a polysaccharide solution claim 1 , iodixanol claim 1 , an organic solvent claim 1 , a liquid wax claim 1 , an oil claim 1 , a gas claim 1 , olive oil claim 1 , mineral oil claim 1 , silicone oil claim 1 , immersion oil claim 1 , mineral oil claim 1 , paraffin oil claim 1 , silicon oil claim 1 , fluorosilicone claim 1 , perfluorodecalin claim 1 , perfluoroperhydrophenanthrene claim 1 , perfluorooctylbromide claim 1 , organic solvents claim 1 , 1 claim 1 ,4-Dioxane claim 1 , acetonitrile claim 1 , ethyl acetate claim 1 , tert-butanol claim 1 , cyclohexanone claim ...
