Abstract
The present invention is a Liquid transport member with significantly improved liquid handling capability, which has at least one bulk region and a wall region that completely circumscribes said bulk region, and which comprises a port region, whereby the bulk region has an average fluid permeability kb which is higher than the average fluid permeability kp of the port regions.
Claims48
Liquid transport member comprising at least one bulk region and a wall region that completely circumscribes said bulk region, said wall region further comprising at least one inlet port region and at least one outlet port region, wherein said bulk region has an average fluid permeability kb which is higher than the average fluid permeability kp of the port regions and said port regions have a ratio of fluid permeability to thickness in the direction of fluid transport, kg/dg of at least 3*10−15 m.
A liquid transport system comprising a liquid transport member according to any of the preceding claims and a source of liquid that is outside the liquid transport member, or a sink of liquid that is outside the liquid transport member, or both a source of liquid and a sink of liquid that are outside the liquid transport member.
