<p>A system is provided for proceeding with automated filtration of liquids in a manner which allows for quantitative collection of desired filtrates or permeates. The system, as well as its associated method, monitors various parameters which are fed to a processor-controlled pump unit. This pump unit has several alternative modes of operation, including controlling the rate of flow through the pump unit. Data are received from one or more pressure sensors and preferably also from a scale. The processor-controlled pump unit operates on these data to control flow velocity and/or filter back pressure within the system.</p> |
