ABSTRACT:
A pressure filtration cell includes a reservoir for liquid to be filtered, a filter at the bottom of the reservoir, and a manually actuable pump for supplying compressed air. The pump is detachable from the reservoir. The air is introduced near the bottom of the reservoir closely adjacent the filter so as to create turbulence in the liquid and across the filter. The turbulence is of a pulsating nature due to the intermittent operation of the pump. Thus, the pump is easily portable for use anywhere and creates a "dynamic" filtration process even without a mechanical stirrer. If used in a laboratory, the cell can be provided with a rotary, magnetically operated stirrer mounted on a relatively short axle.
