ABSTRACT:
An apparatus for sieve filtration, and in particular ultrafiltration using a membrane as the filter, is particularly useful for filtering extremely small initial volumes, in particular of blood plasma or serum, in a pressurized cell with alternating flow direction of the liquid to be filtered, thus preventing concentration polarization, and preventing contact of the liquid to be filtered with any foreign substance such as a pressure gas.
