FIELD: liquids filtration. SUBSTANCE: polymeric filter for microfiltration has membrane, located between two draining bases inside chamber, formed by upper and lower lids with couplings. Lids are made with matching each other grooves and bulges along perimeter and stream distributing members in the form of radial ribs with increasing toward center height. Ribs are in symmetry located on inner surfaces of lids.
