Abstract
An automatic apparatus for the selective extraction of phases from a multiphase system in a receptacle distinguished by their opacity difference comprising a stirrup (1) moveable with respect to the receptacle (2) containing the multiphase system of different opacity (3) and (4), a control means (5) for moving the stirrup (1) which is sensitive to the change of opacity of the phases present in the receptacle (2) and a means (6) for effecting the extraction of the phase secured to the stirrup (1) which is especially suitable for extraction of biological fluids, particularly blood.

An automatic apparatus for the selective extraction of phases from a multiphase system in a receptacle distinguished by their opacity difference comprising a stirrup (1) moveable with respect to the receptacle (2) containing the multiphase system of different opacity (3) and (4), a control means (5) of moving the stirrup (1) which is sensitive to the change of opacity of the phases present in the receptacle (2) and a means (6) for effecting the extraction of the phase secured to the stirrup (1).
An automatic process for the selective extraction of one phase of a multiphase system in a receptacle with the phases having different opacities comprising displacing along the axis of the receptacle (2) a stirrup (1) with a means (5) sensitive to the change of opacity of the phases and a means (6) for effecting extraction of a phase until means (6) penetrates the phase (3) to be removed, extracting the phase (3) with means (6) until means (5) detects the phase (4) of different opacity and then stopping the said extraction.
