| 摘要 |
The present invention concerns a device and a method for filtering molecules that is precise, efficient, reliable, and rapid; it has a low rate of molecular loss, it can be upgraded, and it provides for the automated filtration of molecules according to one or more predefined parameters. The device ( 10 ) for filtration of molecules ( 3 ) comprises three filtration zones ( 11 a- 11 c), each equipped with filtration reservoirs ( 1 ) in which a solution containing molecules ( 3 ) to be filtered is placed. The filtration reservoirs ( 1 ) are separated into two chambers by an isoelectric filter ( 4 ) which allows only selective passage of molecules ( 3 ) according to their isoelectric point (pI) when they are subjected to an electrical field generated by electrodes ( 5 ). This filtration device ( 10 ) comprises a mechanized tool holder ( 20 ) specifically for supporting one or more pairs of electrodes ( 5 ) in order to perform isoelectric filtration in one or more filtration reservoirs ( 1 ) simultaneously.
