A separator tank for separating and retaining a liquid phase from a liquid-gas fluid mixture is suitable for use with cryogenic as well as non-cryogenic liquids, in space experiments or other applications under weightless conditions. The separator tank has liquid storage members of porous, sponge-like metal foam arranged in a tank vessel. The total pore volume and porosity characteristics of the metal foam are selected to provide capillary uptake greater than the total volume of the liquid to be retained. In a preferred example, the liquid storage members are coaxially arranged, radially spaced, annular cylindrical members, with flow passage notches at alternating opposite ends thereof, to form a meandering fluid flow path therebetween. A gas extraction device is provided at the center of the tank. The separator tank and an upstream connected fluid supply tank can be arranged within a cryostat.
