Abstract:
A filter assembly includes a casing having of a polymeric film and bounding a compartment, the casing having an inlet opening communicating with the compartment and a first outlet opening communicating with the compartment. A first filter includes a porous filter body through which gas can pass and has a pore size smaller than 1 µm, the first filter being coupled with the casing so that the filter body is at least partially disposed within compartment of the casing and so that gas passing through the compartment of the casing from the inlet opening to the first outlet opening must pass through the filter body.

Abstract:
A method for filtering a gas includes sparging a gas through a liquid within a compartment of a container. In one embodiment the container can comprise a flexible bag. The sparged gas is passed from the container through a gas filter of a filter assembly. A partial vacuum is applied to the gas filter so that the partial vacuum assists in drawing the gas through the gas filter.

Abstract:
A method and system for achieving a gas-liquid mass transfer includes delivering into a compartment of a container a liquid, the liquid having an exposed top surface disposed within the compartment. A stream produces turbulence on the top surface that is sufficient to achieve the gas of a gas is passed over the top surface of the liquid so that the stream of gas liquid mass transfer. In one embodiment the liquid is a culture that includes cells or microorganisms and the mass transfer functions to oxygenate the culture sufficient to sustain the cells or microorganisms.
Abstract:
A sample purification system includes a container assembly bounding a sample purification compartment and having an upper end and an opposing lower end, the sample purification compartment comprising mixing zones and settling zones. A plurality of shielding elements are positioned within the sample purification compartment so as to at least partially separate adjacent mixing zones and settling zones or separate adjacent mixing zones, the mixing zones being in fluid communication with the settling zones. A mixing element is disposed within each mixing zone. An acoustic wave settler is aligned with a portion of the container assembly, the acoustic wave settler being configured to emit an acoustic wave through the portion of the container assembly and a mixture disposed therein, the acoustic wave coalescing fluid phase droplets disposed in the mixture to increase the buoyancy or density of the fluid phase droplets.
