Abstract:
A container for carrying a fluid sample therein, and being adaptable for use with a centrifuge which separates components of the fluid sample by density into component layers, the container comprising:a fill well section defining at least one fill well therein, adaptable to receive the fluid sample;a cavity section, defining a plurality of fluid expansion cavities therein, such that each of the fluid expansion cavities is adaptable to receive a portion of the fluid sample therein, and includes a respective fluid receiving area having a first cross-sectional area and a respective fluid expansion area viewable from outside the container and having a second cross-sectional area smaller than the first cross-sectional area, the fluid expansion areas each expanding a viewable surface of at least one of the component layers of its respective portion of the fluid sample when the fluid sample carried in the container is centrifuged, and the fluid expansion areas of at least two of the fluid expansion cavities are disposed at different distances from a respective end of their respective fluid expansion cavity; anda channel section, defining a channel system which provides communication between said at least one fill well and the fluid expansion cavities.
