ABSTRACT:
Venting means for venting gas from the transfer line of a liquid delivery system comprising a housing, a first, liquid-wettable, microporous membrane carried in said housing so as to be in communication with the transfer line, a second, non-liquid-wettable, gas permeable microporous membrane superimposed on said microporous membrane to the outward side of the housing. Gas in the delivery system is vented from the system so long as the first microporous membrane remains unwetted by the delivery liquid.
