The present invention is a Liquid transport member with significantly improved liquid handling properties, having at least one bulk region completely circumscribed by a wall region, and which comprises at least one port region, where the product of the bubble point pressure of the port region multiplied with the bulk region permeability is higher than half of the product of the porosity of the member multiplied by the surface tension of the transported liquid.
L'invention concerne un élément de transport de liquides présentant des propriétés de traitement de liquides sensiblement améliorées. Cet élément comporte au moins une zone centrale complètement entourée par une zone périphérique et comportant au moins une zone d'orifice. Dans cet élément, le produit de la pression de point de bulle par la perméabilité de la zone centrale est plus élevé que la moitié du produit de la porosité de l'élément par la tension superficielle du liquide transporté.
