Abstract:
A liquid dispensing method and system for dispensing from a container including an outer container and an inner container, a portion of the inner container occupied by the liquid, a remainder of the inner container occupied by a headspace gas. The system includes a probe having a flow passage therein and a gas passage communicating between the interior of the inner container and an exterior of the outer container. Fluid (such as air or nitrogen) is caused to flow under pressure into a space between inner walls of the outer container and the inner container to force the headspace gas out of the inner container via the gas passage and to force liquid out of the inner container through the flow passage in the probe to a manufactuaring process.
Abstract:
A method for testing the integrity of a filter comprising porous filter material having a bubble point, the filter having an expected specific liquid flow value, the method comprising: providing a filter fixture with an inlet for fluid flow and outlet for fluid flow; installing said porous filter in the filter fixture between the inlet and the outlet; wetting the porous filter material to fill the pores of the material with a wetting liquid; filling the filter fixture between the porous filter media and the fluid outlet with a liquid, pressurizing the filter fixture by providing gas at the fluid inlet of the filter fixture at a pressure lower than the bubble point of the filter, measuring the liquid flow out of the filter fixture.
