Abstract:
A method for culturing a microbial or cellular seed culture includes positioning a first flexible bag (68) within a chamber (40) of a first retainer (14), the first retainer (14) being secured to a mixer table (12). A culture (82) is produced within a compartment (80) of the flexible bag (68), the culture (82) comprising a growth media and a microbial or cellular starter culture added thereto. The mixer table (12) is activated so that the culture (82) is mixed within the compartment (80) of the first flexible bag (68) while the microbes or cells of the culture grow, the culture (82) having a maximum volume of less than 10 liters.
Abstract:
A mixing system for mixing a liquid includes a first impeller segment (170A) having a first mount (172A) and a first mixing blade (174A) secured to the first mount (172A) and a second impeller segment (170B) having a second mount (172B) and a first mixing blade (174B) secured to the second mount (172B), the second impeller segment (170B) being separate and discrete from the first impeller segment (170A). One or more drive members are secured to the first impeller segment (170A) and the second impeller segment (170B) for concurrently rotating the first impeller segment (170A) and the second impeller segment (170B) about a rotational axis (171). The first impeller segment (170A) and the second impeller segment (170B) are secured to the one or more drive members so that a plane (210) extending normal to the axis (171) of rotation intersects with the first mixing blade (174A) of the first impeller segment (170A) and the first mixing blade (174A) of the second impeller segment (170B).
Abstract:
A foam sensor system includes a flexible bag comprised of a polymeric material and bounding a compartment. A foam sensor assembly is mounted on the flexible bag and includes a foam contact disposed within the compartment of the flexible bag. A ground assembly is mounted on the flexible bag and includes a ground contact disposed within the compartment of the flexible bag, the foam sensor assembly and the ground assembly being configured so that an electrical potential can be applied between the foam contact and the ground contact.
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 condenser bag includes a body bounding a channel that extends between an inlet opening at a first end and an outlet opening and an opposing second end, the body being comprised of a polymeric film. An intake port is secured to the body at the inlet opening and bounds an port opening that extends therethrough and communicates with the channel. A tubular transfer line has a first end coupled with the body so as to communicate with the channel at a first location located between the inlet opening and the outlet opening and an opposing second end coupled with either the intake port so as to communicate with the port opening therein or with the body so as to communicate with the channel at a second location located between the intake port and the first location.

Abstract:
A system for mixing a liquid solution or suspension, comprising a container assembly and a condenser bag (102). The container assembly comprises a collapsible bag (12) bounding a compartment, the collapsible bag being comprised of polymeric film and adapted to hold a fluid; a sparger at a lower end of the collapsible bag for delivering gas into the compartment; an exhaust port secured to an upper end of the collapsible bag and bounding a port opening that communicates with the compartment. The condenser bag comprises: a body (164) bounding a channel (178) that extends between an inlet opening (184) at a first end (179) and an outlet opening (185) at an opposing second end (181), the body being comprised of a polymeric film; and an intake port (166) secured to the body at the inlet opening and bounding a port opening that communicates with the channel. The intake port of the condenser bag is coupled with the exhaust port on the collapsible bag so that at least part of the body is disposed at an elevation above the upper end of the collapsible bag.
