    Abstract: A mechanical separator for separating a fluid sample into first and second phases is disclosed. The mechanical separator includes a float having a first portion and a second portion, a ballast circumferentially disposed about a section of the float, and a deformable bellows defining an open passageway extending between a first end and a second end. The ballast is longitudinally moveable with respect to the float and engaged with the deformable bellows between the first end and the second end. At least a portion of the float is transitionable from a restraint position to a sealed position through the first end of the bellows. The first portion of the float can be positioned within the interior of the deformable bellows in the restraint position, and the first portion of the float can be positioned at an exterior location longitudinally displaced from the deformable bellows in the sealed position.

    Abstract: A method for detecting the presence of a microorganism in a fluid sample is disclosed. The method includes providing a fluid specimen within a specimen collection container having a sidewall defining an interior therein. The interior includes a mechanical separator adapted for separating the fluid sample into first and second phases within the specimen collection container and a sensing element capable of detecting the presence of a microorganism disposed therein. The method includes subjecting the specimen collection container to applied rotational force to isolate a concentrated microorganism region. The method also includes detecting by a sensing element the presence or absence of a microorganism within the concentrated microorganism region.

    Abstract: A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.

    Abstract: A mechanical separator for separating a fluid sample into first and second phases is disclosed. The mechanical separator includes a float having a passageway extending between first and second ends thereof with a pierceable head enclosing the first end of the float, a ballast longitudinally moveable with respect to the float, and a bellows extending between a portion of the float and a portion of the ballast. The bellows is adapted for deformation upon longitudinal movement of the float and the ballast, with the bellows isolated from the pierceable head. The float has a first density and the ballast has a second density greater than the first density. The bellows is structured for sealing engagement with a cylindrical wall of a tube, and the pierceable head is structured for application of a puncture tip therethrough. The separation device is suitable for use with a standard medical collection tube.
