Provided is a centrifugal separation container for separating a material from tissue and body fluids by using a centrifugal force, including: a first container; a second container; a first piston positioned in the inside of the first container and configured to be movable up and down in the inside of the first container; an elastic body positioned below the first piston in the inside of the first container and configured to elastically bias the first piston upward; a first connecting duct having one end connected to the first container and the other end connected to the second container; and a first control valve operating by a centrifugal force and configured to open and close the first connecting duct.

Centrifuge rotor comprising a rotor assembly adapted for centrifugal rotation around a rotation centre axis, with a plurality of centrifuge tube beds, each with a longitudinal axis, wherein each centrifuge tube bed comprises a tubular cavity which is defined by a cavity sidewall and a cavity bottom which together act as a bearing surface for the outer surface of a centrifuge tube when received in said centrifuge tube bed, wherein at least one of the plurality of cavity bottoms comprises at least one extraction aperture, which connects the tubular cavity to the exterior of the rotor assembly, preferably wherein at least one closure device is removably fastened to the rotor assembly to seal each of the at least one extraction apertures in an airtight manner.

A centrifugal separator includes a cylindrical bowl, a core tube assembly, and an annular piston disposed around the core tube assembly and inside the inner surface of the bowl. Feed liquid is injected down the core tube assembly into the lower portion of the bowl, raising the annular piston. During a separation mode, the bowl rotates at high speed, separating solids from the feed liquid to accumulate along the inner surface of the bowl, while collecting clarified centrate as it exits the top of the bowl and through the core tube assembly. Following solids accumulation, bowl rotation is stopped and residual liquid is pumped from the bowl. In a solids discharge mode, the annular piston is urged downward along a vertical axis in response to compressed gas. The downward movement of the piston forces accumulated solids from the bowl via an opening in the lower end thereof.

In a centrifugal machine, collecting chambers, which are in a rotary bowl allocated to centrifugal separation of at least two phases, include a discharge port that can be opened or closed as desired by pistons, movement of which is controlled from outside by a reduced-friction system. Drawing volume is adjustable and proportional to volume of a transverse aperture in the pistons, the ports and the openings of the collecting chambers being offset. The machine enables pseudo-continuous drawing which makes it possible to maintain a continuous supply. The drawing volume, composition of the drawn product, and compactness thereof, in a case of a near-solid phase, are controlled.
