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.

The device of claim 7, wherein the center of mass is offset from a center of the through-hole. 9. The device of claim 7, wherein the center of mass is offset from the through-hole. 10. The device of claim 7, wherein a center of volume is located within the through-hole, and is offset from the center of mass. 11. The device of claim 7, wherein at least a portion of the separator has a spheroid shape. 12. The device of claim 7, wherein the through-hole is defined within the float. 13. The device of claim 7, wherein the float is adapted for deformation in a direction substantially perpendicular to the through-axis upon applied rotational force to at least one of the device and the separator. 14. A device for separating a fluid sample within a collection container, comprising: a separator having a through-hole defined therethrough along a through-axis, the through-hole allowing fluid to pass therethrough, the separator comprising:a float, having a first density; anda ballast, having a second density greater than the first density, wherein a portion of the float is connected to a portion of the ballast, wherein the separator has a center of volume that is located within the through-hole,wherein the separator has a first diameter taken along a first side of the through-hole which is different than a second diameter taken about a second opposite side of the through-hole, and wherein the first and second diameters are parallel with the through-hole. 15. The device of claim 14, wherein the center of volume is located on a through-axis of the through-hole. 16. The device of claim 14, wherein the center of volume is offset from a center of mass of the separator. 17. The device of claim 16, wherein the center of mass is offset from a through-axis of the through-hole. 18. The device of claim 16, wherein at least a portion of the separator has a spheroid shape. 19. The device of claim 16, wherein the through-hole is defined in part by the float and in part by the ballast. 20. The device of claim 16, wherein the float is adapted for deformation in a direction substantially perpendicular to a through-axis of the through-hole upon applied rotational force to the separator.
