An apparatus for separating fluids is formed essentially of three pieces which may be nested together to form a stacked array. The three pieces are a cap, an extraction cartridge housing a separating column, and a primary recovery cup. A secondary recovery cup may also be nested onto the lower end of the waste cup. The primary recovery cup has interior flanges for positioning and protecting the bottom end of the column against damage. Each of the elements has an enlarged upper portion forming an exterior step which facilitates mounting in the swinging bucket of a centrifuge. The column itself may comprise particles of a suitable separatory material with the top and the bottom of the particles retained by porous supports.

Apparatus for processing fluids comprising, in combination, an extraction cartridge having an enlarged middle portion, tapered inward toward its lower end, adapted to receive said fluids and a tubular lower portion communicating with said middle portion, separating column material disposed in said lower portion, the bottom end of said lower portion defining a nozzle for fluids passing through said lower portion, a first container, the interior lower end of said container defining longitudinal interiorly extending radial guides for positioning said lower portion of said extraction cartridge and protecting said nozzle, the top portion of each of said extraction cartridge and said first container defining enlarged sections of equal inside diameter, a closure member insertable into the top end of either said extraction cartridge or said first container, said extraction cartridge middle portion and said first container each formed to have a mating taper to permit the nesting and sealing of said cartridge in said container, whereby said separating column material and said nozzle are protected and sealed when said closure member is inserted in said cartridge and said cartridge is nested in said first container.
