Abstract:
1. A separation assembly for enabling separation of a fluid sample into first and second phases, comprising: a collection container having a first end, a second end, and a sidewall extending therebetween, the collection container defining a longitudinal axis between the first end and the second end; and a mechanical separator comprising a separator body having a through-hole defined therein, and at least one sealing perimeter, the separator body adapted to transition from a first initial position in which the through-hole is oriented in an open position for allowing fluid to pass therethrough, to a second sealing position in which the through-hole is oriented in a closed position for preventing fluid from being received therethrough, upon applied centrifugal force, wherein, in the second position, the at least one sealing perimeter sealingly engages a portion of the sidewall of the collection container to prevent fluid from passing between the separator and the sidewall and to prevent fluid from passing through the through-hole, wherein at least a portion of the through-hole is oriented along the longitudinal axis of the collection container in the first initial position, and wherein at least a portion of the through-hole is oriented perpendicular to the longitudinal axis of the collection container in the second sealing position.
