Rotor and method for automatically processing liquids for laboratory and bioanalysis purposes.

摘要

A rotor assembly (160) for processing a liquid comprises: a rotor body (52) which can be rotated about an axis of rotation (5), said rotor body (162) comprising a discrete chamber (197) within which is processing step is performed and a passageway communicating with said discrete chamber (197); a transfer means (164) movably positioned within said passageway for transporting a substance along said passageway to said discrete chamber (197), said transfer means (164) comprising a magnetically-attractable material (218); and moving means (168) for moving said transfer means (164) along said passageway toward said discrete chamber (197). The moving means (168) comprises a magnetic field-generating means for generating a magnetic field adjacent to said transfer means (164) so that a magnetic field acting upon said magnetically-attractable material (218) moves said transfer means (164) along said passageway.
