Claim:
1. A centrifuge tube, comprising: a housing configured to mount in a centrifuge to rotate the housing about a rotation point spaced from the housing; and a mixing chamber disposed within the housing and configured to mix a first component and a second component during rotation of the housing, the mixing chamber including: a container configured to receive the first component and the second component; an obstacle structure contained within the container and configured to move relative to the container from a first position to a second position and mix the first component and the second component in the container in response to a change in centrifugal force imparted by rotating the housing between a first rotational speed and a second rotational speed; and a connection piece contained within the container and connected at one end to the container and at a second end to the obstacle structure, the connection piece formed integrally with one or more of the container and the obstacle structure, wherein: when the housing is rotated at the first rotational speed, a first centrifugal force is imparted on the obstacle structure and positions the obstacle structure at the first position, when the housing is rotated at the second rotational speed, a second centrifugal force is imparted on the obstacle structure and positions the obstacle structure at the second position, and the obstacle structure moves from the first position to the second position when the rotational speed of the housing is changed from the first rotational speed to the second rotational speed.
