Apparatus and method for separating and concentrating fluids containing multiple components

A system for separating and extracting selected fractions from a container, the system comprising:

• a separation system, including:
• a connection member extending a length between a first end and a second end;
• a first separation member having a first density and moveable along said length of said connection member;
• a second separation member having a second density different than said first density and fixed near said second end of said connection member;
• wherein said first separation member is operable to move relative to said second separation member along said length of said connection member;
• a collection volume defined between a first collection face of said first separation member and a second collection face of said second separation member;
• wherein a first selected fraction of the selected fractions is operable to be collected from said collection volume.

A system for separating and extracting selected fractions from a container, the system comprising:

• a first separation member and a second separation member interconnected with a connection member having a throughbore through the connection member;
• a collection volume formed between the first separation member and the second separation member within the container;
• a tube connected to a connection portion of the connection member an extraction system operably connectable to the tube to extract at least one of the selected fractions from the collection volume;
• and
• an extraction port extending through a wall of the container to connect the extraction system to form a passage to the collection volume through the connection member;
• wherein at least a portion of at least one of the selected fractions is contained within the collection volume after a centrifugation of said first separation member, said second separation member, and said connection member within the container;
• wherein the tube is substantially permanently connected to said connection portion to allow access to the collection area between the first separation member and the second separation member;
• wherein said first separation member has a first density and said second separation member has a second density that is higher than said first density;
• wherein the first separation member has a first collection face and the second separation member has a second collection face;
• wherein the first collection face is a convex surface having a first angle and the second collection face is a concave surface having a second angle, where the first angle and the second angle are substantially complementary.
