    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 container for storing a biological sample for molecular diagnostic testing and/or histological testing is provided. The container includes a first chamber for receiving a sample holder therein, a second chamber, and a closure for enclosing the container. A breakable membrane, such as a piercable foil, extends within the container and separates the two chambers. When the breakable membrane is broken, fluid can pass between the first and second chambers. The membrane may be broken through an activator on the closure, such as a depressible member or a rotatable carrier, causing the sample holder to break through the membrane.
