Claim 0:
1. A self-sealing venting fluidic system comprising:
a fluid conduit comprising an inner serface;
a fluid check-valve for venting gas from the fluidic system, the fluid check-valve comprising:
a retention body defining a fluid aperture having an upstream side and a downstream side;
a hydrophilic porous material held by the retention body and disposed to cover the fluid aperture;
a hydrophobic porous material held by the retention body and disposed to cover the fluid aperture and adjacent the hydrophilic porous material,

wherein one face of the hydrophilic porous material is in fluid communication with the upstream side of the aperture, and one face of the hydrophobic porous material is in fluid communication with the downstream side of the aperture,
wherein the hydrophilic porous material is configured to retain liquid from the upstream side to hinder passage of gas from the downstream side to the upstream side, and the hydrophobic porous material is configured to hinder passage of liquid from the upstream side to the downstream side, and
wherein the fluid check-valve is fitted within the fluid conduit and forms a fluidic seal with the inner surface of the fluid conduit to separate the fluid conduit into an upstream side to contain a gas and a liquid, and a downstream side to receive the gas; and
a plunger adapted to fit within the fluid conduit, wherein the plunger comprises the fluid check-valve.
