Abstract
A device for separating heavier and lighter fractions of a fluid sample is provided, the device including a container and a unitary separator located therein, the separator having an overall density between the heavier and light fractions. The separator is capable of moving between the fractions upon centrifugation, and sealing the fractions from one another when centrifugation ends.
Claims9
A method for manufacturing a biological fluid collection container having therein a separator for separating components of a collected fluid sample, the method comprising:
- providing the biological fluid collection container;
- and
- placing the separator into the container, wherein the separator is manufactured by a method comprising the step of injecting one or more polymers into a mold to form a unitary component comprising at least one feature selected from the group consisting of at least two regions of differing densities and a density gradient, wherein at least a portion of the separator is adapted to deform upon application of rotational force.
