ABSTRACT:
A spin filter for removing substantially cell-free medium from a stirred suspension culture vessel, wherein a stationary baffle is arranged in the interior space of the spin filter to disrupt liquid flow therein and minimize the tendency of cells to collect on and foul the inner-facing filter surfaces, the filter surface being sized to substantially exclude materials greater than about 8 to 10 microns, and the spin filter being rotatable independent of, and in a rotational direction opposite to, the vessel stirring device.
