MECHANICAL SEPARATOR FOR SEPARATION OF A FLUID SAMPLE, SEPARATION SET TO ENABLE THE SEPARATION OF A FLUID SAMPLE AND METHOD OF ASSEMBLY OF A MECHANICAL SEPARATOR

摘要

density separation device. it is a mechanical separator for separating a fluid sample in the first and second phases. the mechanical separator includes a floating element that has a passage that extends between the first and the second end of the same, with a pierceable head that encloses the first end of the floating element, a ballast longitudinally movable in relation to the floating element and a bellows that extends between a part of the floating element and a part of the ballast. the bellows is adapted for deformation under the longitudinal movement of the floating element and the ballast, with the bellows isolated from the pierceable head. the floating element has a first density and the ballast has a second density higher than the first density. the bellows is structured for the sealing coupling with a cylindrical wall of a tube and the drillable head is structured for the application of a drilling tip through it. the separation device is suitable for use with a standard medical collection tube.
