Abstract
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.
Claims20
A system comprising:
- a tube comprising
- a first end,
- a second end comprising an aperture,
- a biological suspension comprising a target material, and
- a collection segment between the first and second ends, the collection segment comprising
- 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 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, and
- wherein the cannula extends through the closed end of the processing vessel.

A method comprising the steps of:
- providing a tube comprising
- a first end,
- a second end comprising an aperture,
- a biological suspension comprising a target material, and
- a collection segment between the first and second ends, the collection segment comprising
- 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;
- inserting a processing vessel comprising a closed end into the cavity of the tube, wherein the cannula extends through the closed end of the processing vessel;
- adding a displacement fluid having a density greater than a density of the target material to the processing vessel;
- and
- centrifuging the tube, the displacement fluid, and the processing vessel, wherein during centrifuging, the displacement fluid flows into the tube via the cannula to displace the target material from the tube which flows into the processing vessel through the cannula.
