Abstract
A filtration unit containing a filtering membrane, a cover upstream of the membrane, and a base downstream of the membrane, and joined together, characterized in that the filtering membrane has an elliptical shape. This elliptical shape facilitates the use for filtration and allows the unit to be reused without the formation of an air lock when the filtering membrane is partially hydrophobic.
