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.

Abstract: A label and labeling system for identifying the volume of a specimen within a specimen collection container are disclosed. The system includes providing a specimen collection container having an open top end, a closed bottom end, and a sidewall extending therebetween forming an interior adapted for receiving a specimen therein. The specimen collection container also includes a label having a label body disposed over at least a portion of the sidewall, in visual alignment with a colored background. At least one of the sidewall of the specimen collection container and the label body have printing disposed thereon having a color that is substantially identical to the colored background against which the specimen collection container will be viewed. At least one of the sidewall of the specimen collection container and the label body may have colorless indicia having a surface enhancement feature for providing visual distinction.

Abstract: A label and labeling system for identifying the volume of a specimen within a specimen collection container are disclosed. The system includes providing a specimen collection container having an open top end, a closed bottom end, and a sidewall extending therebetween forming an interior adapted for receiving a specimen therein. The specimen collection container also includes a label having a label body disposed over at least a portion of the sidewall, in visual alignment with a colored background. At least one of the sidewall of the specimen collection container and the label body have printing disposed thereon having a color that is substantially identical to the colored background against which the specimen collection container will be viewed. At least one of the sidewall of the specimen collection container and the label body may have colorless indicia having a surface enhancement feature for providing visual distinction.
