  • the separator Under the action of the centrifugal force, the separator separates from its original position and moves to a sealing position. Because the density of the entire separating body is in a range of values between the density of the blood serum and the density of the blood cake, the separating body automatically positions itself exactly at the phase boundary between blood serum and blood cake. This position is also called sealing position, because the separating body in this position sition with its sealing edge circumferentially sealing against the inside of the tubular sample tube and thus cleanly separates the blood serum from the blood cake. The separating body maintains this sealing position even after the end of the centrifuging, so that the blood serum and the blood cake are separately available for a laboratory examination.

Under the action of a force, in particular the centrifugal force, the separating body is to be released from its starting position and migrate into the sealing position described above.
  • this release from the starting position should only take place when the force on the separating body is greater than the predetermined force threshold; in particular, the release from the starting position should not take place at the wrong time, for example, not when the tubular container with the separating body therein experiences a shock during transport in the starting position.

This makes it possible to flow around the separating body with the liquid inside the tubular container. Because the sealing edge is typically not attached to the ballast body, this elasticity is not required by the ballast body; this can therefore be less elastic.

Le corps de séparation comporte un corps flottant (110) réalisé dans un matériau élastique et présentant un bord d'étanchéité périphérique (112), et au moins un corps de lestage (120) fixé sur la face inférieure du corps flottant (110). La densité du corps de lestage (120) est supérieure à la densité du corps flottant (110) et la densité de l'ensemble du corps flottant (100) se situe dans une plage de valeurs entre la densité de la première phase et la densité de la deuxième phase du liquide. L'invention vise à garantir qu'un détachement du corps de séparation à partir d'une position de départ dans le récipient n'ait lieu que de manière contrôlée sous l'effet d'une force prédéterminée. A cet effet, le corps de lestage (120) présente selon l'invention, à son extrémité opposée au corps flottant (110), un coefficient de frottement statique prédéfini sur sa surface ou comporte au moins un élément adhésif (122) qui présente sur sa surface le coefficient de frottement statique prédéfini.
