Claims23
A device for separating a fluid into constituent components comprising:
- an inner container forming a sedimentation compartment for receiving a sample of the fluid, the inner container having an inlet port and a first aperture;
- an outer container for receiving the inner container and having a second aperture;
- a breachable diluent reservoir, wherein upon breach the internal volume of the diluent reservoir is in fluid communication with the sedimentation compartment;
- and
- at least one of the inner container and the outer container being movable between a first configuration where the outer container seals the first aperture and a second configuration wherein the first aperture and the second aperture align to form an outlet for a separated component of the sample fluid.
