ABSTRACT:
The present invention is a deformable liquid handling member, having an inner region circumscribed and hermetically sealed by a wall region, which comprises a membrane assembly to separate a first zone outside of the member from a second zone within the inner region of the member. Thereby, the second zone is connected to a suction source capable of receiving liquid, and the first zone is positioned in liquid communication with a liquid releasing source during its intended use. The membrane assembly is capable of maintaining a pressure differential between the second zone and the first zone without permitting air to penetrate from said first zone to said second zone. Further, the inner region comprises an inner material, which has a volume expansion factor of more than 3, preferably 5, more preferably 10, and can have a creep recovery of more than 60%, preferably more than 90%.
