Abstract
The present invention relates to a method and device for separating and transferring container (1) contents by dynamical use of centrifuge force, transferring a specific volume of liquid (A) from a recipient (1) to another (2) without contact with any external element other than the initial container (1) itself. Therefore, the present invention is useful for transferring for example part of a blood sample (A) from a tube (1) without touching the blood sample, also dispensing with a disposable needle as is currently usual. The invention is also advantageous as it allows keeping in the original container (1) a predetermined portion of the sample (B). By rotating the container, with a sufficiently high speed, over an axis (x) located at the boundary of the parts (A, B), the sample is split at a predetermined position. A preferred embodiment comprises the container at an angle (V) to the rotation axis (x).
